On the Nature of Edward Gordon Craig's Über-Marionette
Authors: Le Bœuf Patrick
Published: May 2010

There is no scholarly consensus about the precise meaning of the term ‘über-marionette’, as coined by Edward Gordon Craig. Is it a life-size marionette? A masked dancer? Or simply a metaphor for an actor who exerts perfect control over his body and emotions? The present article, based, among other sources, on recently discovered material in the Edward Gordon Craig Collection of the National Library of France, gives a brief overview of several perspectives regarding this issue before proposing another hypothesis – that the über-marionette may actually have been a full-body puppet. Patrick Le Bœuf is a library curator at the National Library of France, and was in charge of the Edward Gordon Craig Collection from 2006 to 2009.
Student Theatre in Poland: Vehicles of Revolt, 1954–57 and 1968–71
Authors: Tyszka Juliusz
Published: May 2010

Polish student theatre was a unique artistic movement in the Soviet post-war empire, with a liberty of expression unparalleled elsewhere in the Soviet bloc. As in every political system, in any country, its creators and its public were students and young intellectuals. These theatre-makers used the umbrella of the Polish Students' Union – a surprisingly democratic institution in a totalitarian political order – and all attempts at their repression were usually appeased by the activists of the student organization, often the friends and supporters of the theatre-makers. After the creation of the Socialist Union of Polish Students these activists became more dependent on the Communist Party, but the Party establishment decided, in the period of the ‘thaw’ (1954–57), that the student artistic movement would be maintained as a kind of artistic kindergarten for avant-gardists and supporters of artistic and political revolt, to let them manifest their beliefs within the well-guarded, limited territory of student cultural centres. However, the young rebels overcame these restrictions and created a focus of artistic opposition which had a wide social and artistic influence, especially during subsequent periods of political crisis. Juliusz Tyszka was himself an activist in the student theatre movement in the late 1970s and early 1980s. Now an NTQ advisory editor, he is head of the Unit of Performance Studies, Institute of Cultural Studies, Adam Mickiewicz University at Poznań, Poland.
Acts of Commitment: Activist Arts, the Rehearsed Reading, and Documentary Theatre
Authors: Paget Derek
Published: May 2010

The past two decades have seen a remarkable resurgence in documentary theatre in Britain and America, with a growing emphasis on verbatim material. In this article, Derek Paget examines a distinctively twenty-first-century contribution to the tradition of activist theatre grounded in the last century. Using verbatim material, supporting a specific current cause, and often produced in association with an NGO or charitable organization, the ‘rehearsed reading’ apparently offers little in terms of theatricality even if it is clearly worthy and a valuable resource for activists. Documentary theatre has always been heavily context-based, and so tends to come to the fore in troubled times. In the present conjuncture, work like that of the ‘Actors for Human Rights’ group, analyzed here, seeks to be a force for social change through a focus on single issues and a reliance on verbatim speech. Derek Paget's interest in documentary theatre has featured several times in NTQ and his early intervention on Verbatim Theatre featured in NTQ 12 (November 1987). Research for the article was conducted as part of University of Reading's 2007–2010 ‘Acting with Facts’ project (funded by the Arts and Humanities Research Council). Derek Paget is Principal Investigator of the project, and Reader in Theatre and Television in the Department of Film, Theatre, and Television, University of Reading. The second edition of No Other Way To Tell It, his book on screen docudrama, is due for publication this year.
Children's command of plural and possessive marking on Hebrew nouns: a comparison of obligatory versus optional inflections*
Authors: SCHIFF RACHEL , RAVID DORIT , LEVY-SHIMON SHANY
Published: May 2010

We compare learning of two inflection types – obligatory noun plurals and optional noun possessives. We tested 107 Hebrew-speaking children aged 6–7 on the same tasks at the beginning and end of first grade. Performance on both constructions improved during this short period, but plurals scored higher from the start, with improvement only in changing stems. The main remaining challenge in mastering noun plural marking in grade school is thus to learn the various types of stem changes. In contrast, possessives improved across the board in first grade, with higher success on non-changing stems and first person suffixes respectively. This intense gain in first grade occurs when children learn to read and write and turn to the written modality as their main source of linguistic input. The study thus testifies to the impact of the shift from spoken language to the ‘language of literacy’ on children's construal of Hebrew morphology.
Importance and impacts of intermediary boundary organizations in facilitating payment for environmental services in Vietnam
Authors: PHAM THU THUY , CAMPBELL BRUCE M. , GARNETT STEPHEN , ASLIN HEATHER , HOANG MINH HA
Published: May 2010

Intermediaries are seen as important actors in facilitating payments for environmental services (PES). However, few data exist on the adequacy of the services provided by intermediaries and the impacts of their interventions. Using four PES case studies in Vietnam, this paper analyses the roles of government agencies, non-government organizations, international agencies, local organizations and professional consulting firms as PES intermediaries. The findings indicate that these intermediaries are essential in supporting PES establishment. Their roles are as service and information providers, mediators, arbitrators, equalizers, representatives, watchdogs, developers of standards and bridge builders. Concerns have been raised about the quality of intermediaries’ participatory work, political influence on intermediaries’ activities and the neutral status of intermediaries. Although local organizations are strongly driven by the government, they are important channels for the poor to express their opinions. However, to act as environmental services (ES) sellers, local organizations need to overcome numerous challenges, particularly related to capacity for monitoring ES and enforcement of contracts. Relationships amongst intermediaries are complex and should be carefully examined by PES stakeholders to avoid negative impact on the poor. Each of the intermediaries may operate at a different level and can have different functions but a multi-sector approach is required for an effective PES implementation.
Assessing the quality of seagrass data collected by community volunteers in Moreton Bay Marine Park, Australia
Authors: FINN PAUL G. , UDY NICOLA S. , BALTAIS SIMON J. , PRICE KEIRA , COLES LOUISE
Published: May 2010

Volunteer-collected data have become widely used, largely because of a perception of cost efficiency, however, the quality of these data is often questioned. This paper analyses the quality of visual estimates of seagrass cover collected by trained volunteers in Moreton Bay (Australia) which has c. 25 000 ha of seagrass habitat. Seagrass was routinely monitored by trained volunteers at 51 sites (50 × 50 m area of intertidal flat) using standardized protocols. Volunteers walked three transects at low tide and assessed the percentage of substrate covered by seagrass within quadrats (50 × 50 cm in area) using photographic guides. Of 33 samples (quadrats) taken at each site, nine (27%) were photographed and later scored by coordinating scientists. The visual estimation of per cent seagrass cover by volunteers was highly correlated with that of scientists and can therefore be used as a reliable source of base-line information about seagrasses in Moreton Bay. The qualities of this successful community-based monitoring programme include expert scientific and multi-organizational involvement, simple methods and result dissemination.

Il n’existe pas de données sur l’offre de service en réadaptation pour les aînés ayant subi un accident vasculaire cérébral (AVC) selon le type de régions. Une enquête a permis de documenter l’offre des services de réadaptation proposés à la clientèle aînée de 65 ans et plus ayant subi un AVC. Au total, les répondants de 295 ressources localisées dans trois régions sociosanitaires du Québec ont complété un questionnaire postal décrivant les services offerts en termes de type d’interventions (associées à neuf aptitudes et à sept domaines de participation sociale) et de type de services (évaluation, réadaptation active, maintien). Les résultats indiquent que l’offre de services de réadaptation proposée par le plus grand nombre de ressources aux personnes âgées ayant subi un AVC concerne les aptitudes motrices et les déplacements. De façon inattendue, au niveau d’interventions associées à quatre aptitudes et à deux domaines de participation sociale, l’offre de services en réadaptation active apparaît plus élevée dans les régions incluant des zones rurales qu’en région métropolitaine.
A dynamic physical model for soil temperature and water in Taylor Valley, Antarctica
Authors: Hunt H.W. , Fountain A.G. , Doran P.T. , Basagic H.
Published: May 2010

We developed a simulation model for terrestrial sites including sensible heat exchange between the atmosphere and ground surface, inter- and intra-layer heat conduction by rock and soil, and shortwave and longwave radiation. Water fluxes included snowmelt, freezing/thawing of soil water, soil capillary flow, and vapour flows among atmosphere, soil, and snow. The model accounted for 96–99% of variation in soil temperature data. No long-term temporal trends in soil temperature were apparent. Soil water vapour concentration in thawed surface soil in summer often was higher than in frozen deeper soils, leading to downward vapour fluxes. Katabatic winds caused a reversal of the usual winter pattern of upward vapour fluxes. The model exhibited a steady state depth distribution of soil water due to vapour flows and in the absence of capillary flows below the top 0.5 cm soil layer. Beginning with a completely saturated soil profile, soil water was lost rapidly, and within a few hundred years approached a steady state characterized by dry soil (< 0.5% gravimetric) down to one metre depth and saturated soil below that. In contrast, it took 42 000 years to approach steady state beginning from a completely dry initial condition.
A review of the Santiago Purple Heron Ardea purpurea bournei, with a report of a new colony
Authors: Hazevoet C. J.
Published: May 2010

The Santiago Purple Heron Ardea (purpurea) bournei is endemic to the island of Santiago, Cape Verde Islands. In contrast to nominate purpurea, it nests high in the crowns of large trees. During the 1950s and 1960s, the total population was probably c. 75 pairs, mainly at the now defunct heronry at São Domingos. After the disappearance of that colony during the early 1970s, the only known nesting site was at Boa Entrada, Santa Catarina region, comprising less than 10 pairs. In January 1991, a new colony was discovered at Banana, Ribeira Montanha, with c. 20 recently used nests of which 2–3 had large young in January–February. The current population is thought not to exceed c. 20 pairs. Breeding occurs from late August to March. Apart from two old records in April, there are no records from the non-breeding season. Probably the birds disperse into the mountainous interior of the island after breeding and feed on the dry hillsides. The causes of the decline are unclear, but scarcity of suitable nest-sites and deteriorating climatic conditions may be significant. Because of the extremely small population, the birds and their nesting sites must be protected by law and the local people informed about the birds and their need for protection; educational materials are being developed.
The habitat and status of Spix's Macaw Cyanopsitta spixii
Authors: Juniper A. T. , Yamashita C.
Published: May 2010

Spix's Macaw Cyanopsitta spixii has always been a very poorly known species from the arid interior of north-east Brazil. Previous views that its habitat is buriti palm swamp appear mistaken, as the most recent field observations and the testimony of local people suggest that Tabebuia caraiba gallery woodland along seasonal creeks is a critical habitat component. Owing to widespread destruction of such woodland, during a survey in June/July 1990 only three good patches were found, all failing to regenerate; one held a single bird, and another held birds up to last year.

A Ararinha-azul Cyanopsitta spixii sempre foi uma espécie pouco conhecida no interior árido do nordeste do Brasil. Opiniōes anteriores que o seu habitat é buritizais parecem erradas porque as observações de campo mais recentes e o testimônio dos habitantes locais sugestem que matas de Tabebuia caraiba ao longo de riachos estacionais são um crítico componente do habitat. Devido à destruição extensa deste tipo de mata, durante um levantamento em junho/julho 1990 somente tres áreas boas foram achadas, todas sem regeneração; uma abrigava um único pássaro, e uma outra abrigava pássaros até o ano passado.
Habitat, distribution and status of the Azure-rumped Tanager Tangara cabanisi in Mexico
Authors: Heath Melanie , Long Adrian
Published: May 2010

The Azure-rumped Tanager Tangara cabanisi is a threatened species confined to the mountains of the Sierra Madre de Chiapas in Mexico and neighbouring Guatemala. It occurs on the Pacific and Gulf slopes of the mountain range, but most frequently on the former between 1,000 and 1,700 m. The Azure-rumped Tanager's habitat is a medium height (about 30 m tall) humid evergreen broadleaf forest formation containing elements of both mesophilous forest of higher altitudes and tropical forests of the lowlands. Information from field surveys and more general data from vegetation maps was combined using a geographical information system package to extrapolate and predict distribution of potential Azure-rumped Tanager habitat in the Sierra Madre de Chiapas. It is estimated that a maximum of 112,000 ha remain, although the total was probably never greater than 200,000 ha. Fortunately 43,660 ha (39%) of the maximum total is contained within the El Triunfo Biosphere Reserve, a newly decreed protected area that spans both the Pacific and Gulf slopes in the central portion of the mountain range. Most of the suitable habitat is found within the reserve's buffer zone, an area in which there are several small but expanding communities. The effective protection and future status of the species rests heavily on the conservation of this habitat within the reserve and essentially this depends on the collaboration in favour of conservation between the local people and the conservation managers and, ultimately, the development of viable land-use alternatives that are less damaging to the forest ecosystem.
The status and conservation of the endemic bird species of São Tomé and Príncipe, West Africa
Authors: Atkinson Phil , Peet Nic , Alexander James
Published: May 2010

Fieldwork on the distribution, status and ecology of the endemic bird species of São Tomé and Príncipe was conducted from June to September 1990. The results are here combined with other evidence, notably from recent ICBP-backed fieldwork. Findings largely support existing Red Data Book listings, althoughOriolus crassirostrisis now found only in remote undisturbed areas at low density, and deserves “Rare” status. Particular achievements of the 1990 fieldwork were the first observations since the 1920s ofBostrychia bocagei, Lanius newtoni and Amaurocichla bocagii, the first two being very rare (one seen of each) and the last patchily common (along streams), records of all three being from either Rio Xufexufe or Rio Ana Chaves or both. Primary forest, mature secondary forest and shade forest are all important to the security of the full avifauna of both islands.
The status of the Black CatbirdMelanoptila glabrirostrison Caye Caulker, Belize
Authors: Miller Bruce , Miller Carolyn
Published: May 2010

An evaluation of the relative abundance of the Black CatbirdMelanoptila glabrirostriswas undertaken on Caye Caulker, an offshore island along the barrier reef of Belize, Central America. Although the species is locally abundant in part of the Sian Kaàn Biosphere Reserve in Mexico, the species is facing habitat fragmentation and loss due to development, both along the Mexican coastal areas and on the island habitats in Belize. The Caye Caulker population appears to be the largest in Belize. Transects of fixed radius point counts resulted in 15.5% and mist-netting resulted in 22.4% of all birds recorded being Black Catbirds. The Neotropical migrant Grey CatbirdDumetella carolinensisapparently shares the same habitat on Caye Caulker and comprised 11.2% of all birds netted. The netted Black Catbirds were noted to have substantial fat deposits. The habitat on Caye Caulker is facing probable fragmentation from recent accelerated land speculation and development of an airstrip.
The Blue-cheeked AmazonAmazona dufresniana: a review
Authors: Wege D. C. , Collar N. J.
Published: May 2010

The Blue-cheeked AmazonAmazona dufresnianaoccupies tropical and subtropical forest in north-eastern South America in eastern Venezuela, Guyana, Surinam and French Guiana, where it remains a very little known species, apparently living in scattered pairs in the interior when breeding, but with irregular movements to the coastal regions in (albeit now small) flocks in July and August. Nothing is recorded of its feeding or breeding habits, nor is it known to be at serious risk from habitat loss or trade, although both these factors may have operated against the species in the past. It occurs in two protected areas and deserves to be a target species of any fieldwork in the region aimed at obtaining status information on areas or faunas.
Incidental capture of seabirds in the New Zealand subantarctic squid trawl fishery, 1990
Authors: Bartle J. A.
Published: May 2010

Fisheries observers recorded incidental capture of seabirds during 338 days on Soviet squid trawlers in New Zealand subantarctic shelf waters around the Snares and Auckland Islands in 1990. Seven species were recorded entangled in fishing gear, including very high numbers of breeding adult White-capped Albatrosses Diomedea cauta steadi. The actual level of White-capped Albatross mortality was estimated at 2,300 birds in 1990, and is not considered sustainable. Nearly all albatrosses were killed by collision with the netsonde monitor cable. In New Zealand waters this equipment is carried only by Soviet trawlers, and is considered obsolete. Replacement of this cable by discrete netsonde transducers on Soviet trawlers should be a global seabird conservation priority.
The biology of the Gola Malimbe Malimbus ballmanni Wolters 1974
Authors: Gatter Wulf , Gardner Roderick
Published: May 2010

The Gola Malimbe Malimbus ballmanni survives in two general areas of Upper Guinea Forest, both focused in Liberia adjacent to easternmost Sierra Leone and westernmost Ivory Coast, where the species was first recorded in the 1970s. The eastern population extends over an area of at least 18,000 km2 and may consist of some 20,000 to 50,000 birds, the species being locally common in lowland rainforest. The western population covers at least 200–300 km2, but numbers are hard to judge. Both populations are under severe threat from habitat destruction, particularly the western. M. ballmanni and M. racheliae form a superspecies as the forest-interior counterparts of the canopy-haunting M. scutatus and M. cassini. M. ballmanni is found between 8 m and 22 m in high forest (79% of recorded cases), higher than M. nitens, lower than M. scutatus; it joins mixed bird parties and feeds on insects of the same size-class as in scutatus, smaller than in nitens. Annual life-cycle is seasonally adapted, with nesting when the rains end and in the transitional and dry season, occasionally in the intermediate dry season. Most birds moult in the first half of the year. Nests hang on lianas, in open galleries at 8 to 21 m. Up to five birds may help build a nest, with labour divided between males and females (which also have different song phrases). Biometric data of adult and immature birds are given.
Status and habitat of the White-winged DuckCairina scutulata
Authors: Green Andy J.
Published: May 2010

The endangered White-winged DuckCairina scutulatawas formerly widely recorded from north-east India, Bangladesh, Union of Myanmar (Burma), Thailand, Laos, Vietnam, Cambodia, Malaysia (peninsular) and Indonesia (Java and Sumatra). It was found to be “common” by British ornithologists in areas of India, Myanmar and Thailand in the early part of this century. Since then, deforestation and hunting have caused a major decline to perhaps less than 5% of its original population size. Since 1980 the species has been reliably recorded from 55 sites in seven countries, with a minimum combined population of 336 individuals. A conservation plan has been produced and implementation has begun.
Trade, status and management of three parrots in the North Moluccas, Indonesia: White Cockatoo Cacatua alba, Chattering Lory Lorius garrulus and Violet–eared Lory Eos squamata
Authors: Lambert Frank R.
Published: May 2010

Between October 1991 and February 1992 field surveys on the status of parrots in the North Moluccas were conducted on Obi, Bacan and Halmahera, with principal focus on three significantly traded species, White Cockatoo Cacatua alba, Chattering Lory Lorius garrulus and Violet-necked Lory Eos squamata. Variable circular plots and variable-distance line transects were used to estimate minimum and maximum population densities at each of 18 sites. C. alba and L. garrulus preferred forest, the former largely confined to lowlands to 600 m, the latter occurring more in hilly areas to at least 1,300 m. E. squamata frequented all habitat types, being commoner in disturbed habitats though rarer at higher altitudes. Minimum populations (the first two being global) were 50,000, 46,000 and 66,000 respectively, and minimum estimated captures in 1991 5,120, 9,600 and 2,850, indicating overexploitation of the first two species. To ensure sustainability, total annual catch quotas should be reduced to 1,710, 810 and 1,590 respectively and allow for fair division between islands. Training, enforcement, monitoring, research and habitat conservation are all needed.
The avifauna of the North Selangor peat-swamp forest, West Malaysia
Authors: Nee Kang , Guan Lee Pheng
Published: May 2010

The North Selangor peat-swamp forest occupies an area of about 75,000 ha and has been extensively logged for timber. Of the six sites surveyed, three were located in regenerating or selectively logged areas and contained a higher proportion of forest-dependent species of birds than the other three, which had been extensively cleared by logging and for agriculture. The presence of the nearby Kuala Selangor Nature Park should not diminish the conservation value of the peat-swamp forest, at least where the avifauna is concerned, as their avifauna complement one another.
The rediscovery of the Cebu Flowerpecker Dicaeum Quadricolor, with notes on other forest birds on Cebu, Philippines
Authors: Dutson Guy C. L. , Magsalay Perla M. , Timmins Rob J.
Published: May 2010

The Cebu Flowerpecker Dicaeum quadricolor, considered extinct since 1906, was rediscovered in a very small (<2 km2) patch of largely degraded forest near Tabunan, Cebu island, Philippines, in 1992. This patch also holds at least four of the five other bird forms endemic to Cebu that are known to be extant. There appears to be no other forest with any closed canopy elsewhere on the island, and the Tabunan site, although within the Central Cebu National Park, could disappear within five years (through clearance for firewood by local villagers) without immediate intervention.
A tribute to Ted Parker
Authors: Schulenberg Thomas S.
Published: May 2010

“I'd forgotten how trees full of bird sounds made you sense the world differently.” (Barbara Kingsolver, The Bean Trees)

No one I have ever met was more attuned to bird sounds, or to birds in general, than was Ted Parker. It was from Ted that many of us, who thought that we already knew a thing or two about birds, truly learned how to sense the world.

No matter when one first met, or heard of, Ted Parker, the name was already a legend. I first met Ted over 20 years ago, and like many people at the time I was already somewhat in awe of him. Then he was known for his birding exploits in the United States and in Mexico. Although I did not realize it at the time, he was already studying the birds of South America, and soon would be transforming our understanding of the avifauna of that continent. By the end of the 1970s, within just a few years of his first trip to the Andes, and without benefit of field guides or commerical bird tapes, he was already the field ornithologist of South America.
Ted Parker: a personal memoir
Authors: Collar N. J.
Published: May 2010

It is now two years since the death of Ted Parker, and I still find it extremely difficult to talk or write about him in the past tense. Indeed, I doubt whether anyone linked with him through ornithology or conservation has yet come to terms with the enormity of the loss. At one level, it is simply that he knew so much of Neotropical birds and their habitats, in so much depth and so much breadth: no-one was his match, and no-one expected ever to be so. At another, it is simply that he was so distinct and vivid a personality, much more than merely “charismatic”: superhumanly energetic, trenchantly assertive, irrepressibly good-natured, subversively frank; and always, inexhaustibly, himself. This mix of features made him larger than life — legendary, even — and awesomely enriching to know, even to someone such as myself who, although corresponding with him for years, met him only twice.
Bolivia has the opportunity to create the planet's richest park for terrestrial biota
Authors: Remsen J. V. , Parker T. A.
Published: May 2010

Establishing a reserve of approximately 10,000 km at a strategic location in depto. La Paz, northern Bolivia, would create the planet's richest park for birds and presumably all other forest-dwelling biota that reach peak diversity at tropical latitudes. By connecting puna and montane forest habitats of the Andes with lowland tropical forest and savannas of the Amazon basin, we predict that the proposed reserve would contain at least 1,088 bird species, or roughly 11% of all bird species on the planet. Among these are many threatened species and species with relatively small geographical ranges. The proposed reserve would also include threatened habitats, such as lower montane forest, dry forest, and grassland.

El establecimiento de una reserva de aproximadamente 10.000 km en un lugar estratégico en el departamento de La Paz, Bolivia, crearía el parque de major riqueza de aves en el planeta. Así es de suponer que la flora y fauna que habitan en la área, llegan a su grado máximo de diversidad en las latitudes tropicales. Conectando puna, los hábitats de bosque tropical (áreas bajas) y sabanas de la cuenca del Amazonas, predecimos que la reserva que se propone tendría a lo menos 1.088 especies de aves, o aproximadamente 11% de todas las especies de aves del planeta. Dentro de estas hay muchas especies amenazadas y especies con áreas de rango geográfico muy restringido. Además la reserva que se propone también incluiría hábitats amenazados, como bosque montano, bosque seco y pajonales tropicales.
Natural history and conservation of the endemic avifauna in north-west Peru
Authors: Parker III Theodore A. , Schulenberg Thomas S. , Kessler Michael , Wust Walter H.
Published: May 2010

Roughly 30% of the avifauna of the dry tropical forests of north-western Peru and adjacent south-western Ecuador is endemic to this small region. Large areas in this region, especially on the Ecuadorian side of the border, have been deforested, further heightening the threatened conservation status of this fauna. The largest remaining tracts of forest in this region are in the Bosque Nacional de Tumbes, Peru. This forest, which was visited in 1986 and 1988, holds significant populations of 12 threatened or near-threatened species, and smaller populations of at least three more endangered species. Six species (Aramides axillaris, Thalurania colombica, Picumnus olivaceus, Attila torridus, Arremonops conirostris, Carduelis siemiradzkii) are reported in Peru for the first time. Evidence is presented for seasonal movements of some species, including the threatenedLeptotila ochraceiventrisand in the small Peruvian population ofPionus chalcopterus. Based primarily on vocal evidence, it is proposed thatThamnophilus zarumae and Grallaria watkinsibe recognized as full species, and that “Empidonax” griseipectusbe transferred toLathrotriccus; further work is needed on the species status of endemic forms in other polytypic species such asSittasomus griseicapillus and Pyriglena leuconota.

Aproximadamente 30% de la avifauna de los bosques secos tropicales del noroeste del Perú, y del suroeste de Ecuador, es endémica a esta pequeña región. Extensas areas en esta región, especialmente del lado de la frontera ecuatoriana, han sido deforestadas, aumentando así la amenaza para la conservación de la fauna. Los más grandes vestigios de bosque seco tropical que subsisten en esta región están localizados en el Bosque Nacional de Tumbes en el Perú. Este bosque, que fue visitado en 1986 y 1988, tiene poblaciones significativas de 12 especies amenazadas o con posible amenaza de extinción, y poblaciones pequeñas de 3 especies más que están en peligro de desaparecer. Notas sobre la historia natural son presentadas para 28 especies, incluyendo 11 especies que están amenazadas o en peligro de extinción. Seis especies (Aramides axillaris, Thalurania colombica, Picumnus olivaceus, Attila torridus, Arremonops conirostris, Carduelis siemiradzkii) están reportados en el Perú por primera vez. Evidencia es presentada para movimientos estacionales de algunas especies, incluyendo la amenazadaLeptotila ochraceiventrisy la población pequeña peruana dePionus chalcopterus. Basandose principalmente en evidencia vocal, se propone queThamnophilus zarumae y Grallaria watkinsipueden ser reconocidas como especies y que “Empidonax” griseipectuspuede ser transferido aLathrotriccus. Se necesita más estudios para determinar el estatus de las formas endémicas de especies politípicas comoSittasomus griseicapillus y Pyriglena leuconota.
Red-masked Parakeet Aratinga erythrogenys and Grey-cheeked Parakeet Brotogeris pyrrhopterus: two threatened parrots from Tumbesian Ecuador and Peru?
Authors: Best Brinley J. , Krabbe Niels , Clarke Christopher T. , Best Amanda L.
Published: May 2010

In order to determine whether Aratinga erythrogenys and Brotogeris pyrrhopterus can formally classified as globally threatened species, their distribution, population sizes and ecological requirements are reviewed, together with national and international trade data from the last decade. The study concludes that, on current data, it is not possible to classify the two species formally, but there are strong indications that, at least locally, the populations of the two species are in decline. The causal factors appear to be a combination of high trade levels and habitat loss. It is essential that trade moratoria are implemented, pending the outcome of further research into the species' population sizes, ecology and breeding success, and further work to determine the extent of trade. Interim recommendations are given and it is proposed that future exploitation of the species should continue only when it has been determined that it has a sustainable basis.
Notes on the conservation status of resident diurnal raptors of the middle Cauca Valley, Colombia
Authors: Alvarez-López Humberto , Kattan Gustavo H.
Published: May 2010

Historical and anecdotal data indicate that out of 14 original species of resident diurnal raptors, six have become extinct and two more are considered endangered in the middle Cauca Valley, Colombia. While the decline of several species is related to a drastic reduction of original habitats such as forests and wetlands, three open-habitat species have also suffered population declines. Possible causes include the recent expansion of intensive agriculture (at the expense of cattle-ranching areas), agrochemical pollution, hunting, and factors such as body size, the proximity of the valley to the upper altitudinal limit of most of the affected species, and the relative isolation of the valley from the Caribbean region and the savannas east of the Andes. The need for monitoring projects s i stressed for the vertebrate fauna, including those species considered common in open and disturbed habitats.

Informaciones históricas y anecdóticas indican que de una fauna original de 14 especies de aves rapaces diurnas residentes en el valle medio del rio Cauca, Colombia, se han extinguido seis especies y dos mas se consideran amenazadas. Mientras que la disminucion de algunas especies se relaciona con la drástica reductión de hábitats originales tales como bosques y humedales, tres especies propias de hábitats abiertos también se han visto afectadas. Se identifican como probables factores la expansión de la agricultura intensiva (a expensas de las areas previamente dedicadas a la ganaderia), la contaminatión por agroquimicos, los conflictos con los intereses humanos y ciertos factores como el tamano corporal, la proximidad del valle medio del Cauca al limite superior de distributión altitudinal de estas especies y el relativo aislamiento del valle con respecto de la región del Caribe y de las sabanas al oriente de los Andes. Se relieva la necesidad de establecer programas de monitoreo de las faunas de vertebrados, inclufdas las especies consideradas como comunes en hábitats abiertos y perturbados.

The Bearded TachuriPolystictus pectoralisoccupies lowland grasslands with scrubby vegetation, generally near water, in the Andean grasslands of Colombia at two sites (threatened racebogotensis), savannas in eastern Colombia and the lowland and tepui grasslands of mainly southern Venezuela, Guyana, Surinam, French Guiana and northern Brazil (racebrevipennis), reappearing south of the Amazon in central-southern Brazil, eastern Bolivia (no recent records), Paraguay, Uruguay and northern and central-eastern Argentina (nominatepectoralis). It is an austral summer visitor (October/November to February/April) to central-east Argentina, nesting (commonly in thistles) around December, clutch-size three. It feeds on insects by perch-gleaning, sallying, hover-gleaning and still-hunting. It is unobtrusive and must be commonly overlooked, and in some localities may be moderately well represented. Overall, however, it is scarce and appears to be very patchy in occurrence; grassland habitats within its range have been converted wholesale to farming. New quantitative criteria support earlier qualitative judgement that the species is probably not (yet) threatened, but that it merits near-threatened status. Suggestions that one or all of its three subspecies may be good species are premature; it is not even clear how distinct these forms are as subspecies.
Ecology and conservation of the Red-tailed AmazonAmazona brasiliensisin south-eastern Brazil
Authors: Martuscelli Paulo
Published: May 2010

The Red-tailed AmazonAmazona brasiliensiswas found to be restricted to a complex mosaic of forests growing on the narrow coastal plain of eastern Brazil. The species depends on habitat heterogeneity for both food and breeding. In Sào Paulo state the 1,550 individuals are divided into 16 populations. The global total of the species may be around 3,600 birds. They feed mainly on fruits, flowers and nectar, also occasionally insects. Most nests are found in permanently flooded forest, apparently because of greater cavity availability. Poaching has had a great impact and is the most immediate threat to the species.

Os papagaios dependem da heterogeneidade do ambiente tanto para sua alimentaçāo como reproducao. No estado de São Paulo existem 1,550 papagaios, divididos em 16 grupos. A populaçāo total da espécie pode ser de 3,600 individuos. Os papagaios se alimentam principalmente de frutos, flores e néctar, com alguns casos de insetivoria. A maioria dos ninhos foi encontrada em florestas permanentemente inundadas (caxetais), aparentemente devido a maior disponibilidade de cavidades. A captura para o comércio ilegal tern tido um grande impacto sobre a espécie e é a maior ameaça à sua sobrevivéncia.
Conserving the endemic birds on the Comoro Islands, III: bird diversity and habitat selection on Ngazidja
Authors: Stevens Jan , Louette Michel , Bijnens Luc , Herremans Marc
Published: May 2010

Bird species diversity is investigated in different habitat types on Ngazidja (Grand Comoro), Comoro Islands. Total bird diversity does not differ significantly among different forest types, but the proportion of endemic species, endemic subspecies and non-endemic species does. Both intact mature forests and pioneer forests on the slopes of Mount Karthala are important for the preservation of bird endemism. The forests on La Grille are poor in endemic species, but their bird species diversity is high thanks to non-endemics. Planting ofEucalyptusis useless for endemic birds.Humblotia flavirostris, Turdus bewsheriandNesillas brevicaudataavoid logged forests, butAlectroenas sganziniis numerous in them.Foudia eminentissimais common in forests with bananas planted in the undergrowth.

Notes on the status of Kuhl's LorikeetVini kuhliiin the Northern Line Islands, Kiribati
Authors: Watling Dick
Published: May 2010

Kuhl's LorikeetVini kuhliihas a precarious status reflected by its disjunct distribution in the Pacific, with surviving populations in the Northern Line (Kiribati) and Austral Islands (French Polynesia) some 3,000 km apart, possibly as a result of Polynesian trade in red feathers. The species is extinct in the southern Cook Islands. On Rimatara (Austral Islands), where it is believed indigenous, it is still common but the recent introduction of theRattus norvegicusis of concern. In the Northern Line Islands,R. rattusappears to have all but extirpated the lorikeet on Tabuaeran (Fanning Island), but one small population has apparently survived for over 70 years, an explanation for which may guidein situconservation ofVinilorikeets on ship-rat-infested islands elsewhere. The arid and unpredictable climate of Kiritimati (Christmas Island) may preclude the establishment of lorikeets. Only on Teraina (Washington Island), where over 1,000V. kuhliisurvive, are there no confirmed threats and goodin situconservation potential.
Endemic birds and protected area development on the Da Lat Plateau, Vietnam
Authors: Eames Jonathan C.
Published: May 2010

A study of Thuong Da Nhim and Chu Yang Sin Nature Reserves - identified as priority sites because located within the Da Lat Plateau Endemic Bird Area (EBA) in Vietnam -was conducted between 10 November 1993 and 1 February 1994. A total of 212 bird species, of which 11 are considered globally threatened (including the rediscovered Grey-crowned CrociasCrocias langbianis), were recorded in the reserves. Eight restricted-range species were recorded, including the four species confined to the EBA. These two reserves are of international importance because they jointly support bird communities representative of the EBA. They are also of great economic importance, being within watersheds. Their extent is believed adequate but it is not known if they encompass all representative habitats over the full altitudinal range. Local tribal communities traditionally practise shifting cultivation, which has greatly modified the extent, composition and quality of evergreen forest and is causing its increasing fragmentation. Deliberate fires are preventing the regeneration of evergreen forest and promoting the growth of a climax dominated byPinus kesiya. This reduces bird diversity and compromises the future of the endemic bird taxa. Other threats include recent logging activities, human immigration, the urban expansion of Da Lat and consequent increasing demand for charcoal and fuelwood. The Ministry of Agriculture and Rural Development should urgently proceed with the production of management plans for these areas, aiming to create a single, enlarged protected area. The primary land-use management strategy should be to conserve remaining areas of evergreen forest and to increase their extent by boundary realignment, elimination of shifting cultivation and fire, and the introduction of sympathetic forestry practices.
Rediscovery of the Grey-crowned Crocias Crocias langbianis

Published: May 2010

The Grey-crowned Crocias Crocias langbianis, previously known from three specimens collected near Da Lat, Lam Dong province, Vietnam, was rediscovered in Chu Yang Sin Nature Reserve, Dak Lak province, in January 1994. Subsequent fieldwork at this site in March and April 1995 revealed the presence of a population inhabiting lower-montane evergreen forest. The species was recorded during an eight-day period. The species appears to have highly specific ecological requirements and several management recommendations are made which would reduce the level of threat to the habitat of the species at this site.
Conservation of the Dark-rumped Petrel Pterodroma phaeopygia of the Galápagos Islands, 1982–1991
Authors: Cruz Justine B. , Cruz Felipe
Published: May 2010

Early work on the Dark-rumped Petrel Pterodroma phaeopygia of the Galápagos Islands, Ecuador, identified colony sites and population status and alerted wildlife managers to an alarming decline in nesting numbers. Predation by introduced mammals, such as rats, cats, pigs and dogs, is the chief concern, followed by loss of nesting habitat to agricultural development. Programmes to reduce predation through poisoning and hunting, begun in 1983, increased the number of chicks fledged from the main breeding colony in eight out of nine years. Pre-breeding adults were lured by tape-recordings to ‘safe’ sites where they successfully raised chicks in artificial nests. Tape-luring offers hope for establishing new colonies on predator-free islands.
Causes of the decline of the Gouldian Finch Erythrura gouldiae
Authors: Tidemann Sonia C.
Published: May 2010

Populations of Gouldian Finch Erythrura gouldiae, an estrildid endemic to northern Australia, declined markedly during the last two or three decades. A survey revealed the species in two areas of Northern Territory, with an estimated 2,000 individuals, including juveniles. Recaptures were low either because of mortality or dispersal. Gouldian Finches eat predominantly Sorghum spp. seeds, but consume other seeds before Sorghum ripens. Other finches declined as cattle increased. Gouldian Finches breed in tree hollows of predominantly two species of eucalypts that grow on rocky slopes. They require water within about 4 km of the nest site. There was no shortage of nesting hollows at the known breeding sites. Fires in the early to mid-dry season allow birds access to seed without damaging trees, but later fires can destroy trees with nest hollows and remove shade. Average clutch-size is 5.2. About 72% of eggs laid, and 63% of nests, fledged young. Pairs lay up to three clutches in a season (February-August), the length of which may depend on rainfall during the preceding wet season. Air-sac mite (Sternostoma tracheacolum), found in 62% of Gouldian Finches sampled, may be preventing the species recovering to former numbers. New colonies of Gouldian Finches should be identified, populations monitored, and habitat managed by effecting patchy burns by low-intensity fires early in the dry season.
Re-establishment of an endangered subspecies: the Norfolk Island Boobook Owl Ninox novaeseelandiae undulata
Authors: Olsen Penny D.
Published: May 2010

The Norfolk Island Boobook Ninox novaeseelandiae undulata is confined to the small, isolated Norfolk Island group, an Australian territory. On morphological and biogeographical grounds, it is here classified as a large, distinctive subspecies of the New Zealand Morepork N. novaeseelandiae. In 1986 only one specimen, a female, survived. A shortage of large trees with suitable nesting holes appeared to be the immediate problem. The Australian Nature Conservation Agency, islanders and New Zealand wildlife authorities have cooperated in an attempt to re-establish an owl population in situ. Nest-boxes were erected in trees in the area frequented by the female and were used readily as roosts. In September 1987, two male New Zealand Moreporks were introduced. The female paired with one male and produced four hybrid F offspring (in 1989 and 1990). Two of these paired in mid-1991 and have since produced five F offspring (two in 1993 and three in 1994). The original female remains paired but now appears to be reproductively senile. At present there seems to be a shortage of mature males, since two female offspring are paired and both lay eggs and attempt to incubate them in the same nest; and a lone female has established a territory. In early 1995 all eleven owls appeared to be alive in the wild. The effort is low-cost, requires relatively little manpower, is carried out with minimal disturbance to the owls, and goes hand in hand with other conservation programmes.
