This biographical study is primarily concerned with the political, economic, and social activities and interests of Mr. Denious while he served in the capacity of State Senator and Lieutenant Governor. In the course of state growth and development, it is unfortunate that important contributions by certain dedicated public servants are little known or remembered. In a small way, it is the purpose of this study to help rectify this situation.
Tweeting the IR
Authors:   University of Nebraska-Lincoln, Royster Paul
Published: February 2023

Social media has become an important means of keeping up to date for busy IR managers. Limited to short, pithy messages, but permitting linking and re-tweeting, the Twitter medium is both handy and powerful … when used appropriately. Alternatively, it can become a portal to fascinating, entertaining, horrifying, and time-consuming off-topic content and even an avenue for online harrassment. The presentation for DC-HUG will involve audience participation, and will include discussions of appropriate forms of identity, good and bad avatars, who to follow for scholarly communications subjects, whom to avoid for greater peace of mind, what are appropriate subjects, how to separate professional and personal topics. Tweets are now included in the Plum Analytics—so we want to explore ways of boosting those results while also keeping our IR community involved and informed. Some IR's can tweet in an official capacity, while other libraries (including mine) forbid that. Audience comments and participation will be an essential part of the contribution. The session will present a roster of scholarly communications personalities, with commentary on their standing and attitudes towards IRs specifically. Discussions of tweeting frequency, what is worth tweeting about, and how to respond to annoying tweets (hint: don't) should provide a lively and informative session.

Homogenization of Fish Faunas and Concurrent Anthropogenic Impacts on Plains Streams in Western Kansas: 1854–2003
Authors: Eberle Mark , null null , null null , null null
Published: February 2023

The fish faunas of the Kansas and Arkansas river basins in western Kansas were signifi cantly dissimilar at the time the Kansas Territory was established in 1854. The faunas were no longer dissimilar 150 years later. This homogenization of the faunas resulted primarily from extirpations, although additions of nonnative species, which now constitute 40% of extant faunas, also contributed. Two periods of changes in the faunas were associated with concurrent anthropogenic changes to the landscape that altered stream habitats. Early extirpations of native species (prior to 1920) occurred in clear, perennial creeks and were concurrent with rapid increases in human population and row-crop agriculture associated with increased demands on perennial water sources and increased sediment yields in streams. Late extirpations of native species and widespread additions of nonnative species (after 1960) occurred in formerly large, often turbid rivers with seasonally variable fl ows and were concurrent with increases in groundwater mining and construction of impoundments associated with dewatered stream segments, stabilized fl ows in other stream segments, reduced peak fl ows in all rivers during summer, increased lentic habitat, and reduced turbidity.

Baseball Career of Andy Cooper in Kansas
Authors: Eberle Mark , null null
Published: February 2023

Andrew Lewis Cooper was inducted into the National Baseball Hall of Fame in 2006. He was a lefthanded pitcher, who played and managed in the Negro Leagues from 1920 until his death in 1941, mostly for the Detroit Stars and Kansas City Monarchs. Cooper also played baseball in California, Cuba, and the Far East. However, his life before 1920 has been little studied. Andy Cooper was born in Texas, probably in 1897. Although he was a resident of Waco and began playing baseball in northern Texas, contemporary newspaper reports document an African American pitcher from Texas named Andrew "Lefty" Cooper playing for baseball teams in Wichita, Kansas during the summers of 1917 and 1919. In addition, Andy Cooper lived in Wichita during parts of the offseason while he played in the Negro Leagues during the 1920s and 1930s. He also wrote about baseball and his extensive travels in a series of columns for a Wichita newspaper, the Negro Star. This monograph recounts Cooper’s experiences in Wichita and frames some of the questions about his early life still in need of thorough research.
Reflections of a Naturalist: Papers Honoring Professor Eugene D. Fleharty
Authors: Choate Jerry , null null , null null , null null
Published: February 2023

Science and academia tend to be dominated by persons who are utterly brilliant, or who are proficient at self-promotion, or who are willing to sacrifice their personal lives and work twice as hard as their peers, or who exhibit some combination of these attributes. Occasionally, however, someone comes along who is just "ordinary" compared with academic overachievers but whose accomplishments far exceed reasonable expectations. Eugene D. Fleharty is such a person. Although he is extraordinarily bright, few would describe him as utterly brilliant. He has never been inclined to "toot his own horn" or otherwise promote himself. And, although he always works harder than most of his peers, he maintains a diverse personal life that includes family, sports, art, community affairs, and other leisure activities. In my opinion, the thing that sets Gene apart from many of his peers is "focus." Indeed, I know of no utterly brilliant academic overachievers who have become known internationally in several markedly different areas of science while becoming a cutthroat competitor in table tennis and racquetball, developing into an award-winning carver of duck decoys, advising community and state officials about environmental issues, mentoring an impressive list of productive graduate students, and providing the intellectual leadership needed by his academic department as it careened recklessly toward the Twenty-first Century.

Carson City Mints a Base Ball Club, 1869–1870
Authors: Eberle Mark , null null
Published: February 2023

Baseball clubs had been organized in Nevada since at least 1866, but the organization of the Silver Star Base Ball Club (BBC) in Carson City in 1869 marked a change for the sport in the state. Some of the employees at the newly constructed Carson City Mint had experience playing for top ball clubs in the East, and other experienced ballplayers lived in the nearby mining community of Virginia City. The Silver City and Virginia ball clubs initiated intercity competition in 1869. In 1870, the Silver Star BBC picked up players from the Virginia BBC and played six games on a tour in California against teams from San Francisco, Oakland, Sacramento, and Stockton. The ball clubs, games, and associated events are described.

George William Castone: An Integrated Baseball Life at the Close of the Nineteenth Century
Authors: Eberle Mark , null null
Published: February 2023

George William Castone was a black baseball player during the 1880s and 1890s. He pitched for integrated town teams and minor league teams, as well as black clubs, such as the Lincoln Giants in Nebraska and the Cuban Giants in the northeastern United States. Most of his time on the diamond was spent in Colorado, Kansas, and Nebraska, but Castone also played on an otherwise white barnstorming team organized in Salt Lake City that traveled through Montana, Oregon, and California. He was among the few black players on minor league teams in the Colorado State League in 1889 and the Nebraska State League in 1892, before the color line barring black players from organized baseball was firmly drawn. In the early twentieth century, Castone was a waiter and an artist, best known for his oil-on-canvas paintings. He passed away in St. Paul, Minnesota in January 1967, just a few days before his 100th birthday.

"What’s in a name?" Baseball Goes to Town in 1886
Authors: Eberle Mark , null null
Published: February 2023

In 1886, the St. Louis Browns of the American Association defeated the Chicago White Stockings (now the Chicago Cubs) of the National League in a postseason series, the only time an American Association club won the series played from 1884 to 1890. Also in 1886, the Missouri Pacific railroad organized the construction of a rail line in Kansas from Council Grove through Osage City to Ottawa. To commemorate the Browns’ season, the Missouri Pacific named two new stations after Browns’ players: Bushong in Lyon County and Comiskey in Morris County. Albert "Doc" Bushong was a catcher for the Browns, and Charles Comiskey was the club’s first baseman and captain (player-manager). Early reports of the towns named after baseball players contained incorrect information, but more recent publications have correctly described the events. This monograph provides additional details of the events and documents contemporary sources. The town of Comiskey no longer exists, but the small community of Bushong recently became a trailhead on the extensive Flint Hills Trail State Park, which follows the final alignment of the Missouri Pacific railroad bed.
An Annotated List of the Butterflies of Kansas

Published: February 2023

This provisional list summarizes the information currently available on the distribution of the butterflies of Kansas. Presently, this information is widely scattered in the literature and numerous collections and is not readily available to many interested parties. The accompanying maps also demonstrate the many gaps in our present information and will hopefully stimulate further collecting and the production of a more complete list in the near future. This paper is based primarily on collections made by the authors during an intensive statewide survey begun in 1979. It is organized around the "county record," usually a voucher specimen housed at Fort Hays State University. These 4975 voucher specimens (1 specimen/species/county) are mapped as solid circles. Where FHSU voucher specimens are lacking we use literature records (usually, only the earliest) , reports from other collectors and specimens in public and private collections. Some 571 such records are mapped as open circles and each is cited in the text. Only one record per county is given except for rare and unusual species. However, additional records are on file at Fort Hays State University. Contributions by other collectors have greatly enhanced the value of this work.
Canadian Education: Factors influencing the adaption of the E-learning at higher education
Authors: Shah John
Published: February 2023

Despite Instructors' technology expertise and government and institution efforts to adopt e-learning platforms, Canada Higher Education is primarily characterized by a traditional classroom atmosphere. The most significant impediment to the full implementation of these platforms is the organizational aspect. The organizational aspect, according to the same authors, consists of a collection of processes and procedures that help university management, which involves an overview of the various factors that are created, or not, in order to ensure the use of e-learning platforms within a university. Following the previous concept, the introduction of an e-learning platform in Canada universities necessitates adequate organizational frameworks and management processes, which promotes the use of this method. Despite the previously mentioned difficulties in implementing e-learning platforms, Canada universities are changing their conventional learning methods and adjusting to the online learning world (Pinto et al. 2012). In terms of open-source solutions, Moodle is the most widely used and user-friendly e-learning platform in Canada's universities. Moodle includes a number of features, including the ability to create a course website, share information among geographically distributed students, and create quizzes, online assessments, and surveys. The universe of this quantitative research was identified as Canada university students in order to identify the factors influencing the use of LMS platforms. Because of geographical considerations, a convenience sample was chosen. Using this criterion, a greater variety of responses and a representative sample of the population surveyed were obtained. The respondents are made up of 231 male students and 178 female students, with an average age of 21.8%. As it can be seen the findings of research hypotheses, as for first research hypothesis which stated that Computer self-efficacy of Moodle LMS impact their use significantly, the B value is higher than 0.05, S.E value is 0.078, t-value 2.415 and p-value is 0.000 accordingly the first research hypothesis is supported. As for second research hypothesis which stated that System usage has a significant impact on the use of Moodle LMS. the B value is higher than 0.05, S.E value is 0.068, t-value 2.631 and p-value is 0.000 accordingly the second research hypothesis is supported.

Authors: Eugène Chantelle
Published: February 2023

The aim of this paper is to examine the relationship between self-leadership skills and Sustainable Competitive Advantage. The study was carried out at small and medium business in Developed countries. The current research focused on assessing the impact of self-leadership skills (Behaviour-focused strategies, Natural reward strategies, and Constructive thought patterns) to measure the influence on sustained competitive advantage in small and medium businesses in Developed countries. The researchers applied simple regression analysis to measure the influence of each independent variable separately on sustainable competitive advantage as small and medium enterprises in Developed countries. A total of 280 questionnaires were issued, but only 228 participants completed them correctly. The findings revealed that the strongest influence was the behaviour-focused strategies as a self-leadership on sustainable competitive advantage, on the other hand the weakest influence was constructive thought Patterns as a self-leadership on sustainable competitive advantage.
Geography and Politics in A World Divided
Authors: Félix Didier
Published: February 2023

This study attempts to examine the main theories and theorists of geopolitical imagination, arguing for an intrinsic relationship between traditional geopolitics and the development of international relations, both in theory and in practice.  Not only have political geographers been made aware of civil rights unrest and other social conflicts, but they have become interested in public policy issues through their work in urban geography. The fastpaced suburb and the associated need to locate new highways, bridges, and desirable facilities such as schools, supermarkets, and hospitals on the one hand, and harmful facilities such as landfills and polluting industries on the other, have brought to the fore on location conflicts and issues of social and racial justice.
NESTING OF THE SCRUB TANAGER (TANGARA VITRIOLINA) IN ANDEAN ECUADOR
Authors: Freile Juan F.
Published: February 2023

The Scrub Tanager (Tangara vitriolina) occurs in dry inter-Andean valleys of Colombia and northern Ecuador. Even though it thrives in human-made habitats, knowledge about its breeding biology is scarce, with no complete description of its nest. In this paper, I present a detailed description of its nest, eggs, and nestlings, including notes on its breeding behavior. The nest is an open cup constructed with grass fibers, dry sticks, rootlets, plastic fibers, dry leaf litter and other vegetal material, spider web, and mammal hair. It was built near the tip of a hanging vine, supported below by three intertwined twigs, 2 m above ground. The female incubated whitish blue eggs speckled brown for 14–15 days. The male attended closely and brought food to the female several times. Nestlings were fed mostly by the female. The nesting pair did not attempt a second brood at this nest after failure; instead, they collected nesting material from this nest up to three days after nest failure.

VARIATION IN FORAGING STRATEGY WITH FOREST AGE FOR THE BLACK-CROWNED ANTSHRIKE (THAMNOPHILUS ATRINUCHA)
Authors: De Zwaan Devin , Roitberg Bernard
Published: February 2023

Rapid deforestation leads to loss and degradation of avian habitat. Reforestation and natural regeneration create secondary forests that may play an important role in maintaining avian biodiversity. In the tropics, many understory insectivores are absent from secondary forests; however the mechanisms responsible for this pattern are unknown. Differences in foraging behavior can be used to identify changes to the insect community, which may contribute to this pattern. We investigated foraging behavior in a common understory insectivore, the Black-crowned Antshrike (Thamnophilus atrinucha), across three forest-age groups to test the hypothesis that insect (prey) communities differ with forest age. We observed no difference in attack or foraging success rates by Black-crowned Antshrikes, suggesting equal foraging effort during focal observations. However, individuals consumed less high-quality (large) prey in secondary forest. Additionally, foraging range shifted downwards from 8.5 ± 1.3 m to 4.5 ± 0.6 m and was compressed horizontally in secondary forests, reducing inter-vegetation movement during foraging bouts. We suggest that this provides indirect support for a change in the insect community across forest ages. Black-crowned Antshrikes appear flexible in their foraging strategies; an ability that may not be shared by other species. However, reduced biomass consumption coupled with constant attack/success rates suggest individuals are performing poorly in young forest. Further research should investigate the generality of this pattern and the capacity for flexible foraging strategies in other avian species.

Describimos un nido, huevos, hábitat y comportamiento de incubación de Hylopezus nattereri en el Parque Provincial Cruce Caballero (Misiones, Argentina). El nido era una plataforma simple y desprolija, de palitos y hojas secas, con una cámara más elaborada de pecíolos, raíces e hifas del hongo Marasmius. Estaba apoyado en la rama curva de un arbusto a 31 cm del suelo. Los dos huevos medían 24,5 x 19,1 mm y 23,1 x 18,5 mm. Eran blanco opaco con tonalidades celeste‐verdosas, cubiertos por motas irregulares y de diferentes tamaños de color castaño, gris y negro. El nido fue atendido por dos adultos, que diferían en tamaño y coloración. Incubaban el 97% del tiempo estudiado, con turnos que promediaban 65 min (DE: 35 min, rango: 24–104). Uno adulto silbó desde el nido al crepúsculo antes de salir y dejar el nido al individuo que pernoctó. Abstract ∙ First description of the nest, eggs, and incubation behavior of the Speckle‐breasted Antpitta (Hylopezus nattereri) in the Atlantic Forest of Argentina The reproductive biology of the genus Hylopezus is little known. We describe a nest, eggs, habitat, and incubation behavior of Hylopezus nattereri at Parque Provincial Cruce Caballero (Misiones, Argentina). The nest was a simple, loose platform of twigs and dry leaves, with a more elaborate lining of petioles, roots, and hyphae of the fungus Marasmius. It was supported by the curved branch of a shrub, 31 cm above the ground. The eggs measured 24.5 x 19.1 mm and 23.1 x 18.5 mm. They were opaque white with light blue‐green tones, covered with irregular brown, grey and black speckles of various sizes. The nest was attended by two adults, which differed in size and coloration. They incubated 97% of the time we studied the nest, with on‐bouts that averaged 65 min (SD: 35 min, range: 24–104). One adult whistled from the nest at dusk, before leaving the nest to the other adult overnight.
RAPID COLONIZATION OF ECUADOR BY THE TROPICAL MOCKINGBIRD (MIMUS GILVUS)
Authors: Aguilar Juan Manuel , Freile Juan F. , Tinoco Boris A.
Published: February 2023

ABSTRACT Some species benefit from anthropogenic ecosystem disturbance expanding their distribution ranges rapidly into altered areas. Given the current availability of anthropogenic landscapes in the Neotropic, it is important to document cases of species’ range extensions to better understand the factors that influence their distribution. In this manuscript, we document the colonization process of the Tropical Mockingbird (Mimus gilvus) in Ecuador since its arrival from Colombia in 1996, and analyze its range expansion to predict its future distribution based on a potential distribution climate model. Data collected indicate that the species has expanded 300 km southwards since first recorded in Ecuador. Given the availability of suitable climate conditions and the availability of disturbed land, it is expected that M. gilvus will continue its current range expansion southwards, occupying most Ecuador, mainly along inter‐Andean valleys.RESUMEN ∙ La rápida colonización del Sinsonte Tropical (Mimus gilvus) en Ecuador Algunas especies se benefician del disturbio antropogénico sobre los ecosistemas, expandiendo rápidamente sus rangos de distribución hacia áreas alteradas. Dada la disponibilidad actual de paisajes antropogénicos en el Neotrópico, es importante documentar los casos de expansión de rango de las especies para comprender mejor los factores que influyen en la distribución de estas. Aquí documentamos el proceso de colonización del Sinsonte Tropical (Mimus gilvus) en Ecuador, desde su arribo de Colombia en 1996, y analizamos su expansión de rango para predecir su futura distribución en base a un modelo climático de su rango potencial. Los datos obtenidos indicaron que la especie se ha expandido 300 km hacia el sur desde su primer reporte en Ecuador. Dada la disponibilidad de condiciones climáticas favorables y de áreas disturbadas, se espera que M. gilvus continúe su actual expansión hacia el sur, ocupando la mayor parte del Ecuador, principalmente los valles interandinos.

ABSTRACT ∙ There is limited information regarding cases of aberrant plumage in Cracidae. Here we present the first record of aberrant plumage in the White‐throated Piping‐guan (Pipile grayi). The individual with aberrant plumage was predominantly white‐colored, but with pale cream underparts. Unfeathered body parts like the fleshy wattle, bill, and tarsus had pink color. Based on these characteristics we conclude that it likely constitutes a case of “Ino‐light” mutation.RESUMO ∙ Plumagem aberrante em Jacutinga‐de‐barbela‐branca (Pipile grayi Pelzeln, 1870, Cracidae) Informações referentes a aberrações na coloração de plumagem são limitadas.

O indi‐ víduo apresentou plumagem com coloração predominantemente branca, com as partes inferiores com coloração creme. Outras partes do corpo, como barbela, bico e tarso apresentaram coloração rosada. Através destas caracterís‐ ticas fenotípicas e utilizando‐se de chaves de identificação para mutação de plumagem em aves disponíveis na litera‐ tura é suscetível que esta aberração se trate de um caso de mutação “Ino‐light”
PREDATION ON SCARLET MACAW (ARA MACAO CYANOPTERA) CHICKS BY COLLARED FOREST FALCONS (MICRASTUR SEMITORQUATUS) IN THE MAYA BIOSPHERE RESERVE, GUATEMALA

Abstract ∙ Through efforts of the Wildlife Conservation Society, poaching in an important Scarlet Macaw (Ara macao cyanoptera) nesting area in the Maya Biosphere Reserve in Guatemala had been reduced to zero by 2004. However, during long‐term monitoring of the nesting success of Scarlet Macaws in the Maya Biosphere Reserve, unexplained or unknown disappearance of chicks from nests was common despite the aforementioned reduction in poaching. To determine the cause of these disappearances, we installed five video camera surveillance systems in the nest cavities during the 2008 nesting season. Fatal attacks on chicks by Collared Forest Falcons (Micrastur semitorquatus) were recorded at three of these nests. This result highlights natural predation as a limiting factor for the recruitment of new individuals into the Scarlet Macaw population in the Maya Biosphere Reserve even when poaching is suppressed.Resumen ∙ Depredación de pichones de Guacamayas Rojas (Ara macao cyanoptera) por Halcones Selváticos de Collar (Micrastur semitorquatus) en la Reserva de la Biosfera Maya, Guatemala A través de los esfuerzos de la Wildlife Conservation Society, el robo de pichones de Guacamayas Rojas (Ara macao cyanoptera) en una importante zona de anidación de la Reserva de la Biosfera Maya en Guatemala ha sido reducido a cero desde el año 2004. Sin embargo, durante el monitoreo a largo plazo del éxito de anidación de las guacamayas rojas en la Reserva de la Biosfera Maya, la desaparición por razones desconocidas de pichones de los nidos fue común a pesar de la reducción de robos anteriormente mencionada. Para determinar la causa de estas desapariciones, instalamos cinco sistemas de vigilancia de cámaras de video en los nidos durante la temporada de anidación de 2008. En tres de estos cinco nidos se registraron ataques fatales contra pichones por parte del Halcón Selvático de Collar (Micrastur semitorquatus). Este resultado destaca la depredación natural como un factor limitante para el reclutamiento de nuevos individuos en la población de Guacamayas Rojas en la Reserva de la Biosfera Maya, incluso cuando se suprime el robo de pichones.

RESUMEN ∙  El Hued‐hued Castaño (Pteroptochus castaneus) es una especie poco estudiada, endémica de Chile y Argentina. En este trabajo describimos observaciones realizadas durante ocho días sobre un nido con dos pichones de Hued‐hued Castaño en septiembre y octubre de 2015. El nido estaba ubicado en el borde de un camino, a 1 km de la Reserva Nacional Los Queules, Chile central. En base a registros obtenidos de cámara trampa, ambos individuos con‐ tribuyeron a la alimentación de pichones y limpieza del nido. Las visitas con ingreso de alimentos constituyeron solo el 50% de las visitas totales al nido. La tasa de alimentación (0,90 ± 0,15 ingresos/h) fue baja comparada con otras especies de la familia. Registramos un total de cuatro intentos de depredación, de los cuales tres no tuvieron éxito durante nuestra observación: dos intentos por güiña (Leopardus guigna) durante la noche y un intento por Aguilucho (Geranoaetus polyosoma) durante el día; y un intento que pudo haber sido exitoso: intento de depredación por parte de güiña durante la noche que resultó en la desaparición de un pichón, ya que la tasa de alimentación se redujo a la mitad luego del mismo.ABSTRACT ∙ Observations at a Chestnut‐throated Huet‐huet (Pteroptochos castaneus, Rhinocryptidae) nest: parental behavior and predation attempts The Chestnut‐throated Huet‐huet (Pteroptochus castaneus) is a poorly known species, endemic to Chile and Argentina. Here we describe observations made during eight days on a nest with two nestlings of the Chestnut‐ throated Huet‐huet between September and October of 2015. The nest was in a tunnel located in a road bank, 1 km from Los Queules National Reserve, central Chile. Based on recordings from a camera trap, both members of the pair contributed to feeding of nestlings and nest sanitation. Visits bringing food constituted only 50% of the total visits to the nest. Feeding rate (0.90 ± 0.15 trips/h) was low compared to other species of the family. We recorded a total of four predation attempts, in which three were unsuccessful during our observation: two attempts by a kod‐kod (Leopardus guigna) during the night and one by a Variable Hawk (Geranoaetus polyosoma); and one attempt that might have been successful: attempt by kod‐kod during the night resulting in the disappearance of one nestling since the feeding rate halved afterwards.
POPULATION FLUCTUTATIONS OF LESSER RHEA (RHEA PENNATA PENNATA) IN PENÍNSULA VALDÉS, PATAGONIA ARGENTINA
Authors: Frixione Martín Guillermo , De Lamo Daniel
Published: February 2023

Abstract ∙ Most populations of large flightless birds have declined since the last century. In arid ecosystems, overgrazing and climate change are particularly detrimental to soil health. In arid Patagonia these processes may lead to a reduction in primary productivity, potentially affecting the populations of herbivorous flightless birds, such as rheas (family Rheidae). We surveyed Lesser Rhea (Rhea pennata pennata) abundance during the breeding and post‐breeding seasons of 2012/2013 and 2013/2014 in Península Valdés Protected Area, Province of Chubut, Patagonia, Argentina. Linear transect surveys were conducted in September and December (breeding) and in late summer (post‐breeding). Density estimates were corrected by detectability in each kind of habitat. Density was substantially lower for the 2012/2013 season than 2013/2014, probably due to the combination of severe drought and ash‐deposition from the eruption of the Puyehue‐Caulle volcano in 2011. Lesser Rhea adult group size increased with food abundance estimates (EVI, Enhanced Vegetation Index) within the season, suggesting food offer is an important factor affecting Lesser Rhea group size in Península Valdés. Resumen ∙ Fluctuaciones poblacionales del Choique (Rhea pennata pennata) en Península Valdés, Patagonia Argentina Gran parte de las poblaciones de aves no voladoras de gran porte han disminuido en el último siglo. El sobrepastoreo y el cambio climático promueven el deterioro de los suelos en ecosistemas áridos. En la Patagonia árida una reducción de la productividad primaria puede afectar las poblaciones de aves herbívoras no voladoras. Se estimó la abundancia del Choique (Rhea pennata pennata) durante las temporadas 2012/2013 y 2013/2014 en el Área Protegida Península Valdés, Provincia del Chubut, Patagonia, Argentina. Los muestreos fueron llevados a cabo en septiembre y diciembre durante el estadío de cría de pichones y al final del verano en la temporada post‐reproductiva. Las densidades estimadas fueron ajustadas por la variación en la detectabilidad en los diferentes hábitats. Las estimaciones de densidades fueron sustancialmente menores para la temporada 2012/2013 en comparación con la temporada 2013/2014, probablemente en respuesta a la combinación de una severa sequía y la deposición de cenizas provenientes de la erupción del volcán Puyehue‐Caulle en 2011. Los tamaños de grupo de Choique aumentaron con el incremento de las estimaciones en la abundancia de alimento (EVI, Índice de Vegetación Mejorado) para cada muestreo, sugiriendo que la oferta alimenticia es un factor importante que afecta el tamaño de grupo de Choique en Península Valdés.

Abstract ∙ The Pavonine Cuckoo (Dromococcyx pavoninus) usually inhabits forest interior, and, being very difficult to observe, little is known about its behavior. Here we describe a new type of foraging behavior based on observations in two different places, one natural and one anthropic. In both cases, the birds perched on the ground and used their wings and tail to disturb the vegetation, flushing and capturing insects while staying on the ground. As far as we know there are no previous published data on the foraging behavior of this species. Resumo ∙ Descrição de um comportamento de forrageio de Peixe‐frito‐pavonino (Dromococcyx pavoninus Pelzeln, 1870) (Cuculiformes: Cuculidae) O peixe‐frito‐pavonino (Dromococcyx pavoninus) é um habitante de interior de florestas e por ser muito difícil de observar, pouco é conhecido sobre seus comportamentos. Aqui descrevemos um novo tipo de comportamento de forrageio baseado em observações em dois locais diferentes, um natural e um antropizado. Em ambos os casos as aves estavam pousadas no solo e usaram de suas asas e cauda para movimentar a vegetação, desentocando‐ perseguindo os insetos enquanto ainda permaneciam no solo. Pelo que se sabe não há qualquer registro prévio publicado sobre as táticas de forrageio da espécie.

Abstract ∙ Many aspects of the breeding biology of the Chilean Flamingo (Phoenicopterus chilensis) are still unknown. We studied captive breeding Chilean Flamingos at La Plata Zoo, Buenos Aires, Argentina between February and July 2014 to document chick‐aging methods based on molt and coloration of bare parts, such as beak and legs. The development of young was divided in three age categories: 1. Chick (less than 15 days old), with white down and salmon‐ pink beak and red coral legs. 2. Pre‐juvenile (1–3 months old), birds covered with gray down (due to a combination of a double down coat) and when the white down falls, a brownish down coat is more evident. In this stage, the beak had darkened and the legs turned dark gray. 3. The last category is the juvenile (4–5 months old), characterized by the presence of vaned feathers, dorsal feathers are pale brown with a dark raquis, underparts are white and inner coverts have a pale‐salmon coloration; the beak is curved and has a blueish base with a charcoal gray tip and legs are pale gray. The information presented in this study may help to age young Chilean Flamingos in the wild.Resumen ∙ Criterios para determinar la edad de pollos de Flamenco Austral (Phoenicopterus chilensis) en cautiverio basadas en características del plumaje Varios aspectos de la biología reproductiva del Flamenco Austral (Phoenicopterus chilensis) son aún desconocidos. Estudiamos una colonia en cautiverio de Flamencos Australes pertenecientes al Zoológico de La Plata; Buenos Aires, Argentina entre febrero y julio de 2014 para obtener criterios para determinar la edad de los pollos basados en la coloración del plumaje y de las partes desnudas, como pico y patas. El desarrollo de los pollos se dividió en tres categorías: 1. Pollo (menos de 15 días de edad), cubiertos por plumón blanco, pico de color salmón‐rosado y patas rojo coral. 2. Pre‐juvenil (1–3 meses), cubiertos por plumón gris (debido a la combinación de una doble capa de plumón). A medida que el desarrollo avanzó, el plumón blanco se perdió y el plumón de color pardo se hizo más evidente. En este estadio, el pico se oscureció y las patas se tornaron de color gris oscuro. 3. La última categoría, el juvenil (4–5 meses), se caracterizó por la presencia de plumas, las plumas dorsales son de color marrón pálido con un raquis oscuro, las plumas ventrales son blancas y las coberteras inferiores son salmón pálidas. El pico es curvo y tiene una base azulada con la punta gris y las patas tienen una coloración gris pálida. La información presentada en este trabajo provee ayuda para categorizar a los jóvenes de esta especie y puede ser de utilidad en estudios demográficos.

Resumen · La presencia de aberraciones cromáticas en las aves ha llamado la atención de los investigadores desde hace mucho tiempo. En México se ha notado un reciente incremento de artículos publicados referente a este tema. Por ello se planteó como objetivo de este estudio llevar a cabo una amplia revisión sobre la literatura publicada sobre el tema de aberraciones cromáticas en México. Adicionalmente reportamos casos recientes de aberraciones cromáticas para cuatro especies de aves Paloma de Collar Turca (Streptopelia decaocto), Rascador Viejita (Melozone fusca), Gorrión de Worthen (Spizella wortheni) y Gorrión Doméstico (Passer domesticus) observadas en el estado de San Luis Potosí, México, correspondientes a un período de 10 años (2007–2017). En base a la revisión de literatura y datos del presente estudio, reportamos que existen registros de aberraciones cromáticas para México en 31 especies pertenecientes a 22 familias, presentado la familia Icteridae el mayor número de casos en las especies Tordo Sargento (Agelaius phoeniceus), Zanate Mayor (Quiscalus mexicanus), Tordo Ojos Rojos (Molothrus aeneus) y Tordo Cabeza Café (Molothrus ater). Seguido de seis familias representadas por dos especies (Columbidae, Cuculidae, Rallidae, Scolopacidae, Tyrannidae, Emberizidae).Abstract · Color aberrations in Mexican birds: a review and new records from San Luis Potosi Color aberrations in birds have attracted the attention of researchers for a long time. Mexico has seen a recent increase in articles published on this subject. Here, we conducted a comprehensive review of the literature published on the topic of chromatic abnormalities in Mexico. Additionally, we report new records of chromatic aberrations in the plumage of four species Eurasian Collared-Dove (Streptopelia decaocto), Canyon Towhee (Melozone fusca), Worthen᾽s Sparrow (Spizella wortheni), and House Sparrow (Passer domesticus) based on 10 years (2007–2017) of observations in the state of San Luis Potosí, Mexico. Based on the literature review and on our data from this study, we show that there are reports of chromatic abnormalities for Mexico in 31 species belonging to 22 families. Family Icteridae presented the greatest number of cases for the following species: Red-Winged Blackbird (Agelaius phoeniceus), Great-Tailed Grackle (Quiscalus mexicanus), Bronzed Cowbird (Molothrus aeneus), and Brown-Headed Cowbird (Molothrus ater). For other six families, we recorded two species with chromatic aberration records (Columbidae, Cuculidae, Rallidae, Scolopacidae, Tyrannidae, Emberizidae).

Abstract ∙ Several species of raptors that breed in North America migrate to the southern hemisphere during the non-breeding period. The Broad-winged Hawk (Buteo platypterus) is one of them, and its wintering distribution reaches the north and central part of South America, although there are published records for the species in Argentina and southern Brazil. We did an exhaustive search of records of the Broad-winged Hawk for South America, using bibliography, citizen-science initiatives, personal communications, and own records. We obtained 4025 georeferenced records for the 1879–2017 period. Both the numbers of records per year and the geographical range of the species have apparently increased in recent years. We also obtained the first record for Misiones province in Argentina and for Espírito Santo state, in Brazil. The wintering range of this species is estimated to cover 12.5 million km2 of the north central part of South America, including southern Brazil and northern Argentina. While it is possible that the range has expanded 700 km southwards recently, with the data available it is not possible to disentangle this possibility from changes in the distribution of bird observers. Resumen ∙ Determinando el rango invernal del Aguilucho Alas Anchas (Buteo platypterus) en Sudamérica involucrando datos de ciencia ciudadana Varias especies de aves rapaces se reproducen en América del Norte y migran durante los meses de invierno al hemisferio sur. Uno de ellos, el Aguilucho Alas Anchas (Buteo platypterus), alcanza normalmente el norte y centro de Sudamérica, aunque se han publicado registros en Argentina y en el sur de Brasil. Realizamos una búsqueda exhaustiva de registros del Aguilucho Alas Anchas para Sudamérica, en la literatura científica, en proyectos de ciencia ciudadana, comunicaciones personales y registros propios, obteniendo un total de 4025 registros georreferenciados para el período 1879–2017. Tanto el número de registros por año como el rango geográfico de la especie han aumentado en los últimos años. También reportamos el primer registro para la provincia de Misiones en Argentina y para el estado de Espírito Santo en Brasil. La zona de invernada actual de esta especie cubriría aproximadamente 12,5 millones de km2 de la porción central-norte de Sudamérica, incluyendo el sur de Brasil y el norte de Argentina. Si bien es posible que la especie se haya expandido unos 700 km hacia el sur en tiempos recientes, no es posible diferenciar esta posibilidad de cambios en la distribución de observadores de aves.
