LIFESTYLE OF PEOPLE CURRENTLY IN THEIR FORTIES IN TERMS OF THEIR RELATIONSHIP TO PHYSICAL ACTIVITIES
Authors: TILINGER Pavel
Published: February 2023

The aim of our study was to analyse physical activities, wellness activities and other activities of people in their forties, i.e. people aged 40-49, who carry out in their daily lives. We also found out the physical fitness of this age group. To achieve our intention, we used a modified "Questionnaire to find out the physical activities and wellness activities of people in their forties", compiled especially for this occasion. The survey involved 75 women and the same number of men aged 40-49 years. The survey was conducted in 2020, just before the onset of the coronavirus epidemic. We used the statistical program Excel to process the results of the survey. The average age of the respondents was 45.2 years, BMI of men 26.4, women 23.7. Half of the respondents live in a city with more than 50,000 inhabitants, 47 % of women and 41 % of men have a university degree. 73 % of the interviewed men and 85 % of the interviewed women actively take care of their own condition. The most frequently mentioned physical activities realized in the last 12 months were walks (walking, trips, Nordic walking, hiking), followed by sports activities (most often sports games, cycling, swimming, skiing), activities in the fitness centre, group exercises (aerobics, yoga, Pilates etc.), own exercise, sauna and meditation. In the 12-minute running test men reached 1867 m and women 1613 m.

Authors: VALENTA Svatoslav , PSOTTA Rudolf , HRABAL Jakub
Published: February 2023

Abstract: BACKGROUNDː Several studies have examined the effects of creatine supplementation in adult athletes in season or pre-season preparation. However, few studies have examined the effects of creatine supplementation in adolescent soccer players during reduced training in an off-season. OBJECTIVE: The aim of the study was to examine the effects of short-term creatine monohydrate supplementation on the anaerobic performance and body composition in adolescent soccer players during reduced training in an off-season. METHODSː Using a double-blind experiment design, 16 soccer players (aged 18.0 ± 0.8 yr) were randomly assigned to 5 days of either 20 g . day-1  creatine monohydrate (Cr) or placebo supplementation. One day before and a day after the supplementation, participants completed squat and countermovement jumps (SJ, CMJ), 10-m running sprint,  6-s single cycling sprint (CST), an intermittent anaerobic test on a bicycle ergometer (10 x 6s, IAnTBE) and measurement of body composition. RESULTSː Cr supplementation had no significant effect (p > .05) on any performance test. However, effect size values indicated medium or small clinical significance in SJ (d = 0.59), CST (6-s power, d = 0.50; peak power, d = 0.48) and IAnTBE (best peak power, d = 0.44; post-exercise blood lactate concentration, d = - 0.59; fatigue index, d = - 0.28 ). Relative to the placebo, Cr supplementation resulted in a significant increase in body weight (BW) (p = .015). CONCLUSIONSː The results of the study suggest that short-term Cr supplementation administered to adolescent soccer players during their off-season significantly increase body weight and could have small/medium clinical significance effect on improve lower-body maximal anaerobic power output and power output recovery during maximal intermittent exercise. The study also confirms that Cr supplementation is safe and without side effects for adolescent athletes.

Authors: TVRDÍK Jiří
Published: February 2023

Tento příspěvek se věnuje jednomu z nejprobíranějších témat mezi dobrovolníky obecně, a tím je odměna. Přestože ne všichni dobrovolníci vykonávají svou činnost s vidinou zisku, stále se najdou jedinci, kteří své rozhodování staví právě na typu odměny, která jim je organizátorem přislíbena. Článek poukazuje na to, že v různých zemích existují rozdílné způsoby odměňování a nemusejí být vždy jen odlišujícím prvkem pro dobrovolníky (např. uniforma), ale zároveň pomáhají pořadateli budovat image i po skončení samotné události.

DOBROVOLNÍCI NA SPORTOVNÍCH AKCÍCH JAKO AKTIVNÍ ÚČASTNÍCI NOVÝCH VÝZEV TRVALÉ UDRŽITELNOSTI
Authors: MIROVSKÝ Tomáš
Published: February 2023

: Příspěvek se věnuje zapojení dobrovolníků do organizace velkých sportovních akcí a jejich zapojení do nových výzev trvalé udržitelnosti, což je velmi diskutované téma při přípravě a následné organizaci velké sportovní akce.

Dobrovolníci jsou součástí velkých sportovních akcí a v mnoha případech jsou nejpočetnější skupinou organizačního týmu, co se týká počtu zapojených lidí. Proto jsou také velmi důležitou skupinou, kterou je možné do aktivit spojených s užitelností zapojit. A obvykle velmi nadšenou skupinou zapojených lidí, protože se akce účastní ve svém volném čase, bez nároku na honorář, ale s očekáváním získání nových zážitků, zkušeností, přátelství.

A právě potřeba znalosti motivace k účasti na akce a preference způsobů komunikace v době mezi přihlášením na akci a zahájením akce je pro organizátora důležitá pro správné nastavení programu pro dobrovolníky a také způsobů, jak s nimi být v kontaktu a udržet je součástí týmu před zahájením akce.

Výsledky zde prezentované vycházejí z výsledků dotazníkového šetření mezi dobrovolníky na Olympijských festivalech 2020 a 2022 a kterého se zúčastnilo 131 dobrovolnic a dobrovolníků, kteří se projektu aktivně zúčastnili.

Druhá část se týká konkrétních témat problematiky trvalé udržitelnosti, konkrétně dlouhodobé spolupráce s dobrovolníky, jejich zapojení do dlouhodobých aktivit i nad rámec projektu Olympijských festivalů, a také možnosti jejich dalšího vzdělávání v oblasti sportu, olympismus a environmentální výchovy.

The long-established academic journal, Mythlore of the Mythopoeic Society, began using the editor’s platform of the SWOSU Digital Commons in 2017. The executive editor, Janet Croft of Rutgers University, will discuss the differences between her former way of managing submissions, reader reviews, and producing a predominantly print journal to doing the work digitally using the editor’s platform of the Institutional Repository. She will describe advantages and disadvantages to using the platform. This is an opportunity for Institutional Repository administrators to ask concrete questions about the learning curve and experience of a seasoned journal editor who has made the transition to using the Digital Commons editor’s platform. Phillip Fitzsimmons, the administrator of the SWOSU Digital Commons https://dc.swosu.edu/, will discuss the relevance of the use of the Digital Commons platform to the goals of the University. He will use download- and viewer-usage Dashboard maps to show the increasing international readership of these two journals and what it can mean to contributors.
Catalog of the Coreidae, or Leaf-Footed Bugs, of the New World
Authors: Packauskas Richard , null null , null null , null null
Published: February 2023

Studies on the New World Coreidae have languished for more than a century. Neglect of these often large, abundant, and occasionally economically important bugs has been due, I believe, to the lack of means to identify them. Most literature treating the New World Coreidae has been restricted to the North American fauna, except for the recent efforts of Brailovsky (1975 to 2007).

The Rainbow Read-In: A Place to Build Community
Authors:   University of Missouri-Kansas City, Johnson Elizabeth
Published: February 2023

The UMKC University Libraries held the second Rainbow Read-In (RRI) virtually in June 2022. Readers presented either their own works if they identify as LGBTQIA+ or works written by LGBTQIA+ authors. Nine participants presented and sixty people attended. Our first Rainbow Read-In included ten presenters and forty attendees in 2021. The goal of this presentation is to share how we created a safe space to showcase works from within the queer community. The objectives of this program are to discuss the origins of the RRI, the formation of the committee, lessons learned, short- and long-term goals, potential areas for improvement, and examples of the range of queer voices represented. New events usually take time to become established, but our event had a head start. UMKC University Libraries hosted the first African American Read-In (AARI) in 2009. As the co-chair of the AARI committee for six years and the creator of the RRI, this presentation will address how the AARI served as a foundation and inspiration for creating a safe and supportive environment for building community for the RRI. We created the transformative program that we wanted to attend. The initial success of this innovative event proves that, as a bunch of library nerds, if you build it, they will come.

Analyzing Factors Affecting the Effectiveness of Peer Assessment in EFL Teaching
Authors: Rahmatillah Refanja , Fajrita Rizki
Published: February 2023

The use of peer assessment in EFL teaching is increasing due to the focus shift from teacher-centered to student-centered approach. However, factors such as attitudes, motivation, language proficiency and relationship bias are believed to contribute to the effectiveness of peer assessment. This paper aims to analyze how the factors affect the effectiveness of peer assessment implementation in EFL teaching. The method used to analyze is a literature review by examining fifteen prior studies of peer assessment use in EFL context. It is found that there are three factors that affect the effectiveness of peer assessment implementation in EFL setting, which are students’ attitude and motivation, students’ English proficiency, and students’ relationship-bias. All these three factors can be interfered with teacher supports such as by describing the benefits of peer assessment to students, pairing the students with same-level of English proficiency, and applying anonymous evaluation. It is suggested that these three factors need to be carefully considered by teachers in EFL context in order to achieve the success of peer assessment implementation.

This study aims to determine the effectiveness of applying the example non example learning model in learning to write narrative essays in class VII students of SMP IT Nurul Ikhwah, Nagan Raya. The informants of this study were 20 female class VII students. The approach used in this study is a qualitative approach to the type of research, classroom action research (CAR). The design of PTK includes the steps of planning, action, observation, and reflection using two cycles. Data collection techniques used in this study were observation and tests. Observation or observation is a data collection method used to collect research data through observation and sensing. The test is a data collection instrument to measure students' abilities in cognitive aspects or the level of mastery of learning material. The use of examples non examples learning models is very effective in learning to write student narrative essays, in addition to higher student activity when the learning process takes place, student scores also increase after using the examples non examples learning model. This can be seen from the grade VII students of SMP IT Nurul Ikhwah who can meet the minimum completeness criteria which is higher than the assignment to write descriptive essays without using an example non example model. Before using the example non example model, there were 11 students out of 20 students who did not meet the minimum completeness criteria, after using the model, there were 3 students out of 20 who did not pass.

Based on the results of the research, the correlation coefficient on the results above shows 0.673 or is negative so that the relationship between the variables is in a different direction. This can be interpreted that the audio-visual media factor will not affect the learning conditions at MTsN 3 Aceh Barat. With a significance of 0.673> 0.05 that audio-visual media has no significant relationship with learning conditions at MTsN 3 Aceh Barat.
Canadian E-learning platform: Using Moodle for Course Creation
Authors: Rohio Legris
Published: February 2023

The education sector is not really averse to emerging technology, including the Internet. Technology-Enhanced Learning has evolved into a field of study and practice centered on the use of information and communication technologies in teaching and learning. This research aimed to analysis the use of Moodle for course creation as E-learning platform at selected private institutions in Canada. The study took place at chosen private institutions in Canada. To support the research to evaluate use of Moodle for course creation as E-learning platform at private institutions, the researchers used four Moodle creation aspects, first instructors’ technology experience, second was university’s system quality, third was information quality and last was instructors ‘internet experience.  The study used a survey to assess the current study using a quantitative analysis approach. The data was collected at random among 78 instructors from Canada's private institutions. The findings revealed that Instructors’ internet experience as the use of Moodle element has significant positive influence on course creation at 5% level. Furthermore, all beta value is higher than .001. All models have very high adjusted R2 (0.681, 0.627, 0.712, and 0.732 respectively) indicating the ability of the models explaining the variation of course creation due to variation of independent variables is very high.  The F-value shows that the explanatory variables are jointly statistically significant in the model and the Durbin-Watson (DW) statistics reveals that there is autocorrelation in the models.
Capital Structure and Firm Profitability in Developing Countries
Authors: Charles Émile
Published: February 2023

This research intended to investigate the influence of capital structure on private hospitals’ performance using a sample of 162 patients. The researchers used a quantitative approach to evaluate the impact of capital structure (Corporate governance, Ownership structure, and Constructive thought patterns) to measure the influence on sustained competitive advantage in private hospitals in North America. The research sample was chosen using a random sampling method and carried out in various locations in North America. A total of 175 questionnaires were issued, but only 162 participants completed them correctly. The results showed that the most effective relationship was between corporate governance as element of capital structure with firm performance, on the other hand the less effective relationship was between ownership as element of capital structure with firm performance. In addition, our results also suggest that the finance managers should use debts as last alternative in their capital structure. To the end, our study can be extended by incorporating more controlled variables, larger sample and longer period data in the regression models to get better results. Other measures and methodology can also be employed.

Canadian represents a good case study to examine the effect of oil price, because most of its earning dependence on exporting crude oil. Canadian is one of the major oil exporting countries. Generally, the national income depends on crude oil. Oil revenue in Canadian covers 90 percent of Canadian government’s budget and also Canadian economy could be effect by would economic during economic problems. Thus, increasing oil crude oil price can affect on economic growth in Canadian. So it is crucial to use other resource instead of oil revenue as a new strategy to gain national revenue. The main objective of this study is to examine the effects of oil price and oil production value on economic growth. Annual growth rate, compound growth rate and correlation coefficient can be used to estimate of the data. The data is annual data which were converting a period of 21 years from 1995-2017.  As a result, Economic growth is one of the most important sources of economic transformation because it reflects the community's ability to increase productive capacity and optimal investment and also sustainability requirement includes a diversified economy on the face of shocks, dynamically adopts technology and head accumulation human money, competitively can gain relative advantages compared to the other. Thus, it operates within stable, stable economic policies and economic development and there was positively statistically significance between oil price and GDP, oil production value and GDP.

THE STATUS OF THE HOODED GREBE (PODICEPS GALLARDOI) IN CHILE
Authors: Roesler Ignacio
Published: February 2023

The status of the Hooded Grebe in Chile has been uncertain since it was first mentioned for the country 25 years ago. Since the first observation, a new set of records has been published elsewhere, but none of them has comprehensively assessed the status of the species in Chile. These publications hypothesize that the species is either a breeding resident, an occasional visitor, or simply a vagrant in southern Chile. In the present article, I collate and discuss all published (and some unpublished) observations of this critically endangered species in Chile, focusing on the temporal distribution of observations and on habitat characteristics. The distribution of records suggests the existence of two different regions where the Hooded Grebe is observed in Chile. The southern area, at both sides of the Strait of Magellan, includes mainly records of putative vagrants during annual movements, while in the northern area, within Torres del Paine National Park and Puerto Natales, the species seems to be a regular summer resident. So far there are no confirmed breeding records for Chile. Although the present information suggests that the Chilean population is very small and not of great importance for the conservation of species, the northern population could represent the last individuals of the presumably extinct Las Vizcachas Plateau’s population of Argentina.

Detailed knowledge of the migratory strategies is important to understand the ecology and evolution of migration and the conservation of migratory birds The Argentinean federal government declared sheldgeese (Chloephaga spp.) pests in 1930, claiming that they reduce crop yield. Currently sheldgeese have suffered severe reductions in their populations and are the focus of serious conservation concern. From September to April they breed in southern Patagonia (Argentina and Chile) while from May to September they winter mainly in the southern Pampas (central east Argentina). The precise knowledge of their migratory routes is essential to ensure protection of necessary resources and sites needed on their annual journeys. Here, by using a satellite transmitter for the first time we unravel the migration route of an Upland Goose (Chloephaga picta), a species endemic to southern South America with an unknown migration strategy. We received data for 121 days (from September 2014 to January 2015). During this time, the bird migrated 1485 km from the wintering grounds in Buenos Aires Province to the breeding area in Santa Cruz province, Patagonia. Part of the migration route was over the sea. The largest displacement was 817 km in 19 hours, representing a minimum mean speed of 43 km h-1.

USO DE LA FOTOIDENTIFICACIÓN COMO HERRAMIENTA DE SEGUIMIENTO DE PATOS DE LOS TORRENTES (MERGANETTA ARMATA)
Authors: Cerón Gerardo
Published: February 2023

El Pato de los Torrentes (Merganetta armata) es una especie poco conocida que habita ríos de montaña de aguas rápidas desde el sur de Argentina y Chile hasta Venezuela. Debido a que la especie habita en ríos de gran porte, donde es muy dificultosa y arriesgada su captura, se presenta un nuevo método, utilizando la fotoidentificación. Utilizando las líneas de la cabeza de los machos de la especie, que presentan diseños únicos, se pueden generar bancos fotográficos que permitan monitorear individuos a los largo del tiempo. El método ha sido puesto a prueba teniendo en cuenta la estabilidad del patrón entre mudas, la comparación de fotografías de numerosos ejemplares salvajes y de pieles de museos y la capacidad de distintos observadores para distinguir diferentes ejemplares y a los mismos ejemplares en diferentes años.

ABSTRACT ∙ We present evidence supporting a hybrid origin of a hummingbird caught in a mist‐net in Reserva Biológica Uyuca, Honduras in 2011. Following a defined diagnostic approach, the individual in question showed intermediate characters in terms of plumage and measurements between Amazilia cyanocephala and A. beryllina, ssp. devillei. The hybrid combination of A. cyanocephala with the nominate subspecies of A. beryllina has been reported once before from Veracruz, Mexico. This is the first time a hybrid of the ssp. devillei – whose taxonomic status is uncertain – with A. cyanocephala is described.RESUMEN ∙ Un colibrí híbrido del género Amazilia de Honduras Presentamos evidencia que respalda el origen híbrido de un colibrí capturado en una red de niebla en Reserva Biológica Uyuca en Honduras en 2011.

Published: February 2023

Resumen ∙ Globalmente, la reproducción de aves en áreas de invernada es un fenómeno raro. La Golondrina Rabadilla Canela (Petrochelidon pyrrhonota) cría en Norteamérica e inverna en Sudamérica y se conocen cinco intentos de reproducción presuntamente fallidos en el centro‐este de Argentina y centro de Chile. Aquí describimos el primer caso de reproducción exitosa de esta especie en Sudamérica. Una colonia bajo un puente de concreto sobre el Río Tercero (Villa María, Córdoba, Argentina) crió pichones exitosamente por primera vez dentro del área de invernada. La construcción de nidos comenzó el 10 de noviembre 2015 y los últimos fueron abandonados el 20 de enero 2016. De 33 nidos completos, al menos 8 produjeron volantones que dejaron sus nidos entre el 12 y el 28 de diciembre. Se observaron hasta 15 volantones simultáneamente en los alrededores de la colonia. Un nido encontrado el 27 de noviembre de 2015 unos 20 km al NE de Villa Mirasol (La Pampa, Argentina) constituye un nuevo intento de cría en una nueva localidad. Dado lo impredecible del retorno de las Golondrinas Rabadilla Canela a sus colonias, es incierto si establecerán poblaciones de cría regulares en Sudamérica. Es importante monitorear la colonia de cría aquí descripta y relevar puentes de concreto buscando posibles nuevas colonias de cría en Argentina.Abstract ∙ The Cliff Swallow (Petrochelidon pyrrhonota) breeds in South America Worldwide, the breeding of birds in overwintering areas is a rare phenomenon. The Cliff Swallow (Petrochelidon pyrrhonota) breeds in North America and overwinters in South America, and five presumably unsuccessful breeding attempts have been documented during the Austral spring and summer in east‐central Argentina and central Chile. Here we describe the first case of successful breeding of this species in South America. A colony under a concrete bridge over the Río Tercero (Villa María, Córdoba, Argentina) succeeded in raising chicks for the first time on the wintering grounds. Nest‐building began 10 November 2015, and the last nests were abandoned on 20 January 2016. Of 33 finished nests, at least 8 succeeded in raising fledglings that left their nests between 12 and 28 of December. Up to 15 fledglings were observed simultaneously around the colony. A nest found on 27 November 2015 some 20 km NE of Villa Mirasol (La Pampa, Argentina) constitutes a new breeding attempt in a new locality. Given their unpredictable return to colonies, it is uncertain whether Cliff Swallows will establish regular breeding populations in South America. It is important to monitor the colony herein described and to survey concrete bridges looking for possible new colonies in Argentina.
INTERSPECIFIC PARENTAL CARE BY A RUFOUS‐COLLARED SPARROW (ZONOTRICHIA CAPENSIS) AT A NEST OF THE PALE‐BREASTED THRUSH (TURDUS LEUCOMELAS) PARASITIZED BY A COWBIRD (MOLOTHRUS BONARIENSIS)

Published: February 2023

ABSTRACT ∙ Interspecific parental care (IPC) in birds, when one individual helps to rear the offspring of another species, is rare outside the context of brood parasitism. Reports of IPC addressed to non‐brood‐parasitic bird species are mostly anecdotal, and in some cases have been explained as a non‐adaptive response to the begging calls of interspecific nestlings in the vicinity of the helper's own nest. Here, we report a case study of a Rufous‐collared Sparrow (Zonotrichia capensis) feeding three nestlings in a Pale‐breasted Thrush (Turdus leucomelas) nest, including one Shiny Cowbird (Molothrus bonariensis) nestling. The combined feeding rate of the nest owners was not significantly different from that of the helper, which fed all nestlings and removed their fecal sacs. To our knowledge, this is the first IPC case reported for South America, and we hypothesize that parasite begging sounds are one of the proximate causes of this behavior.RESUMO ∙ Cuidado parental interespecífico por um tico‐tico (Zonotrichia capensis) em um ninho de sabiá‐barranco (Turdus leucomelas) parasitado por um chopim (Molothrus bonariensis) Cuidado parental interespecífico (IPC) em aves, quando um indivíduo ajuda a criar filhotes de outra espécie, é raro fora do contexto de parasitismo de ninhada. Registros de IPC direcionado a espécies de aves que não são parasitas de ninhada são geralmente anedóticos, e em alguns casos têm sido explicados como uma resposta não adaptativa às vocalizações dos filhotes de outras espécies na vizinhança do ninho do ajudante. Nesse estudo, registramos um estudo de caso de um tico‐tico (Zonotrichia capensis) alimentando três ninhegos em um ninho de sabiá‐barranco (Turdus leucomelas), incluindo um ninhego de chopim (Molothrus bonariensis). A taxa de alimentação combinada dos parentais não diferiu significativamente daquela do ajudante, que alimentou todos os ninhegos e removeu seus sacos fecais. Ao nosso conhecimento, este é o primeiro IPC registrado na América do Sul, e nós hipotetizamos que os chamados do parasita estão entre as causas próximas deste comportamento.
NOTAS SOBRE LA ANIDACIÓN DEL BIENPARADO COMÚN (NYCTIBIUS GRISEUS) EN EL VALLE GEOGRÁFICO DEL RIO CAUCA (CALI, COLOMBIA)

RESUMEN ∙ El Bienparado Común (Nyctibius griseus) habita desde el oeste de México hasta el norte de Argentina y Uruguay. A pesar de ser una especie común, la información existente sobre su historia natural es muy poca, especialmente sobre su comportamiento reproductivo. En este trabajo proveemos información detallada sobre su biología reproductiva basada en cuatro nidos monitoreados en Cali (Valle geográfico del Rio Cauca, Colombia). Los nidos eran concavidades en la parte superior de ramas truncadas, en cada una de las cuales se encontró un huevo blanco con manchas lila y marrón claro, distribuidas en toda la superficie. Durante la incubación, los padres permanecieron en el nido todo el día hasta las 18:34 ± 00:06 h (rango = 18:24–18:53 h), momento en el cual los adultos dejan desatendido el nido hasta el inicio de la sesión de incubación nocturna, la cual empezó a las 19:08 ± 00:07 h (rango = 19:00–19:15 h). El porcentaje de atención al nido fue de 95,03 ± 0,98% (n = 1 nido). El tiempo de permanencia del polluelo en el nido fue 46 días (n = 1 nido), con una tasa específica de crecimiento (K) de 0,124. La forma del nido, coloración del huevo y cuidado parental registrados aquí concuerdan con reportes previos para esta y otras especies del género. Sin embargo, la atención al nido y la tasa de crecimiento de los polluelos fueron mayores que la registrada en otros estudios.ABSTRACT ∙ Notes on the nesting of Common Potoo (Nyctibius griseus) in the valley of Rio Cauca (Cali, Colombia) Thee Common Potoo (N. griseus) is distributed from west Mexico to northern Argentina and Uruguay. Despite its wide distribution, information regarding its natural history is sparse, in particular concerning its nesting behavior. In this study, we present detailed breeding biology information based on four nests monitored in Cali, Colombia (Río Cauca valley). Nests were concavities on the top of truncated branches where one white egg with lilac and light brown speckles distributed over the entire surface was laid. Based on nest temperature loggers the parents incubated continuously through the day. The first foraging trip in the evening at 18:34 ± 00:06 h (range = 18:24–18:53 h) interrupted incubation until the start of the nocturnal incubation shift at 19:08 ± 00:07 h (range = 19:00–19:15 h). Nest attentiveness was 95.03 ± 0.98% (n = 1 nest). The nestling period lasted 46 days (n = 1 nest), and nestling growth rate (K) was 0.124. Nest shape, egg coloration, and parental care recorded in our study were consistent with previous reports for N. griseus and other species of the genus. However, nest attentiveness and growth rate of nestlings were higher compared with other studies.
OBSERVACIONES DE EVENTOS DE DISPERSIÓN DEL PATO DE LOS TORRENTES (MERGANETTA ARMATA)
Authors: Cerón Gerardo , Capllonch Patricia
Published: February 2023

Resumen ∙ El Pato de los Torrentes (Merganetta armata) es un ave especialista de ríos de aguas rápidas que se distribuye por la cordillera de los Andes desde el sur de Argentina y Chile hasta Venezuela. Aquí aportamos nueva información sobre eventos de dispersión a través de un registro casual y seguimiento de ejemplares anillados en Argentina. Nuestras observaciones sugieren eventos de dispersión crepusculares y nocturnos, un juvenil fue registrado volando de noche sobre tierra firme, a 300 metros del cuerpo de agua más cercano. Las distancias de dispersión fueron en general bajas (2–9 km). Sin embargo, un macho anillado se desplazó entre 22 y 84 km de distancia, dependiendo de si la ruta empleada fue volando sobre tierra firme o realizada siguiendo cursos de agua, respectivamente. Es necesario estudiar la capacidad dispersiva de esta especie para determinar el potencial de aislamiento genético entre poblaciones y probables barreras geográficas.Abstract ∙ Observations on dispersal events of Torrent Ducks (Merganetta armata) The Torrent Duck (Merganetta armata) is a white‐water river specialist distributed along the Andes from southern Argentina and Chile to Venezuela. Here we provide new information on dispersal based on ringed individuals and occasional records from Argentina. Our observations suggest nocturnal or crepuscular dispersal events, a juvenile was recorded flying at night on land, 300 m away from the nearest shore. Dispersal distances were in general low (2–9 km). However, one ringed male dispersed between 22 and 84 km, depending on whether it flew over land or followed watercourses, respectively. It is necessary to study the dispersal ability of this species to determine the potential for genetic isolation between different populations and likely geographical barriers.
OBSERVATIONS OF THE BREEDING BEHAVIOR OF THE YELLOW‐TUFTED WOOD‐ PECKER (MELANERPES CRUENTATUS) IN NAPO PROVINCE, ECUADOR
Authors: Van der Hoek Yntze
Published: February 2023

ABSTRACT ∙ The Yellow‐tufted Woodpecker (Melanerpes cruentatus) is common and conspicuous across most of tropical South America. Nevertheless, there is little information available on its breeding behavior. I describe observations of a breeding pair, made between 15 February and 10 March 2016, near the Biological Reserve Colonso Chalupas in the province of Napo, Ecuador. I observed aggressive interactions between M. cruentatus and Masked Tityras (Tityra semifasciata), likely as a result of competition for nest‐holes. I did not observe cooperative breeding. My observations suggest that breeding in Ecuador may commence as early as February, and that M. cruentatus requires dead, standing tree snags, an element often eliminated from anthropogenic landscapes. The availability of snags should be part of ecosystem management, especially in the buffer zone of a protected area.RESUMEN ∙ Observaciones del comportamiento de anidación del carpintero azulado (Melanerpes cruentatus) en la provincia de Napo, EcuadorEl Carpintero Azulado (Melanerpes cruentatus) es una especie común que se encuentra en gran parte de América del Sur tropical. Sin embargo, hay poca información disponible sobre su comportamiento reproductivo. Detallo observaciones hechas entre el 15 de febrero al 10 de marzo de 2016, sobre una pareja reproductora, cerca de la Reserva Biológica Colonso Chalúpas en la provincia de Napo, Ecuador. Observé interacciones agresivas entre M. cruentatus y Tityra semifasciata, probablemente como resultado de la competencia por huecos aptos para anidar. No observe indicios de reproducción comunal o cooperativa. Mis observaciones sugieren que el periodo reproductivo puede comen‐ zar en febrero en el este de Ecuador y que M. cruentatus requiere árboles muertos en pie para nidificar. Asegurar la disponibilidad de estos árboles debe ser parte del manejo del ecosistema, especialmente en la zona de amortiguamiento de un área protegida.
POLYDACTYLY IN AN INDIVIDUAL OF THE WHITE MONJITA (XOLMIS IRUPERO)
Authors: Perin Marcon Amanda
Published: February 2023

Abstract ∙ Polydactyly is a skeletal malformation which is evidenced by the presence of extra digits in hands or feet. A polydactylous White Monjita (Xolmis irupero) was photographed at Xangri‐Lá, Rio Grande do Sul, Brazil on 8 February 2015. An additional inverted hallux was present on each foot, located distally relative the original digits. The bird could perch properly, did not seem distressed, and was in apparent good health. This anomaly could have been caused by spontaneous mutation due to teratological conditions, environmental factors, or by the lack of essential nutrients during development.Resumo ∙ Polidactilia em um indivíduo de noivinha (Xolmis irupero) Polidactilia é uma má‐formação esquelética que é evidenciada pela presença de dígitos extras em mãos ou pés. Uma noivinha (Xolmis irupero) polidáctila foi fotografada em Xangri‐Lá, Rio Grande do Sul, Brasil em 8 de fevereiro de 2015. Um dedo hálux adicional invertido estava presente em cada um de seus pés. A ave conseguia pousar propriamente, não parecia estar em condições de estresse e aparentava estar em boa saúde. A anomalia pode ter sido causada por mutação espontânea devido a condições teratogênicas, fatores ambientais ou pela falta de nutrientes essenciais durante o desenvolvimento.
NOTES ON THE NESTING BEHAVIOR OF THE GRAY‐MANTLED WREN (ODONTORCHILUS BRANICKII)
Authors: Johnson Oscar
Published: February 2023

Abstract ∙ The Gray‐mantled Wren (Odontorchilus branickii) is a poorly‐known inhabitant of the canopy of mid‐elevation Andean forest, and is a difficult species to study because it occurs at low densities. Almost no natural history information is known for the species, including its nest. In September and October 2016, I observed a pair of wrens actively building a nest in the sub‐canopy of upper montane rain forest in the Cordillera Azul of northeastern Peru at an elevation of 1230 m a.s.l.. The nest of O. branickii consisted of a cavity‐like structure formed by a dried and curled palm frond, into which the wrens were carrying nest material. I also compare the nest of O. branickii to that of the Tooth‐billed Wren (O. cinereus) and to other genera of cavity‐nesting wrens. The nests of O. branickii and O. cinereus are similar, and share characteristics with the nests of Salpinctes, Catherpes, Hylorchilus, and Microcerculus, providing taxonomic support for a relationship between these genera. Resumen ∙ Notas sobre el comportamiento de reproducción del Soterrey Dorsigris (Odontorchilus branickii) El Soterrey Dorsigris (Odontorchilus branickii) es un ave poco conocida del dosel de bosque andino de altura media que es difícil de estudiar porque se encuentra en bajas densidades. Por lo tanto, casi no existe información sobre la historia natural de esta especie, incluyendo el nido. En septiembre y octubre de 2016 observé una pareja de O. branickii construyendo un nido en el sub‐dosel de selva alto‐montana en la Cordillera Azul del noreste de Perú a una altura de 1230 m s.n.m.. El nido de O. branickii consistía de una cavidad formada por una hoja de palmera enrollada, dentro de la cual los individuos depositaban material para la construcción del nido. También comparo el nido de O. branickii con el nido del Soterrey Dientepico (O. cinereus), y con otros géneros de soterreyes que anidan en cavidades. Los nidos de O. branickii y O. cinereus son similares y comparten características con los nidos de especies de los géneros Salpinctes, Catherpes, Hylorchilus y Microcerculus, lo que sugiere que están relacionados taxonómicamente.

Abstract ∙ The Magellanic Horned Owl (Bubo magellanicus) is one of the most common nocturnal raptors in Patagonia. The aim of this note was to analyze the food habits of this species in a small island from the Patagonian Atlantic coast. Four nesting areas and eight adults of Bubo magellanicus were found; 217 pellets plus disaggregated material were collected. We identified 2774 individual prey items. Insects were the most consumed prey (63.56%), followed by reptiles (13.73%), arachnids (10.92%), mammals (10.42%), and birds (1.37%). Our study show B. magellanicus feeding mainly on arthropods and introduced species, a fact that was not previously reported for this species in Patagonia. Resumen ∙ Hábitos alimenticios del Tucúquere (Bubo magellanicus) en una isla de Patagonia, Argentina El Tucúquere (Bubo magellanicus) es una de las rapaces nocturnas más comunes de la Patagonia. El objetivo de esta nota fue analizar los hábitos alimenticios de esta especie en una pequeña isla de la costa atlántica de la Patagonia. Se encontraron cuatro áreas de nidificación y ocho adultos de Bubo magellanicus y se recolectaron 217 egagrópilas además de material disgregado. Identificamos 2774 individuos presa. Los insectos fueron la presa más consumida (63,56%), seguidos por los reptiles (13,73%), los arácnidos (10,92%), los mamíferos (10,42%) y las aves (1,37%). La relevancia de este estudio reside en que B. magellanicus se alimenta principalmente de artrópodos y especies introducidas, hecho que no se había reportado previamente para esta especie en la Patagonia.
