Abstract:
The revealed prevalence of coronaviruses in wild bird populations in Poland was 4.15% and the main reservoirs were birds from orders Anseriformes and Charadriiformes, with a prevalence of 3.51% and 5.59%, respectively. Gammacoronaviruses were detected more often than deltacoronaviruses, with detection rates of 3.5% and 0.7%, respectively. Gammacoronaviruses were detected in birds belonging to six orders, including Anseriformes, Charadriiformes, Columbiformes, Galliformes, Gruiformes, and Passeriformes, indicating a relatively wide host range. Interestingly, this was the only coronavirus detected in Anseriformes (3.51%), while in Charadriiformes, the prevalence was 3.1%. The identified gammacoronaviruses belonged to the Igacovirus and Brangacovirus subgeneras. Most of these were igacoviruses and formed a common phylogenetic group with a Duck Coronavirus 2714 and two with an Avian Coronavirus/Avian Coronavirus9203, while the viruses from the pigeons formed a distinct “pigeon-like” group, not yet officially represented. The presence of deltacoronaviruses was detected in birds belonging to three orders, Charadriiformes, Galliformes, and Suliformes indicating a narrower host range. Most identified deltacoronaviruses belonged to the Buldecovirus subgenus, while only one belonged to Herdecovirus. Interestingly, the majority of buldecoviruses were identified in gulls, and they formed a distinct phylogenetic lineage not represented by any officially ratified virus species. Another separate group of buldecoviruses, also not represented by the official species, was formed by a virus identified in a common snipe. Only one identified buldecovirus (from common pheasant) formed a group with the ratified species Coronavirus HKU15. The results obtained indicate the high diversity of detected coronaviruses, and thus also the need to update their taxonomy (establishing new representative virus species). The serological studies performed revealed antibodies against an infectious bronchitis virus in the sera of white storks and mallards.

Abstract:
Avaliaram-se retrospectivamente as cirurgias realizadas em aves no Serviço de Cirurgia de Pequenos Animais do Hospital Veterinário da Faculdade de Medicina Veterinária e Zootecnia, Universidade de São Paulo, durante período de oito anos. De um total de 90 intervenções cirúrgicas para diagnóstico e/ou tratamento de afecções, 27 foram ortopédicas e 63 de tecidos moles. Quanto ao percentual de cirurgias ortopédicas realizadas segundo as diferentes ordens, observou-se: Psittaciformes 85,19%, Piciformes 7,41%, Anseriformes 3,70% e Falconiformes 3,70%. Para as de tecidos moles os Psittaciformes representaram 92,06%, Columbiformes 3,17%, Passeriformes 3,17% e Anseriformes 1,60%. Entre os tipos de afecções ortopédicas encontradas as fraturas apresentaram a maior ocorrência (88,90%), seguidas de luxação (3,70%), avulsão traumática de extremidade (3,70%) e artrite/osteomielite (3,70%). Dentre as afecções cirúrgicas de tecidos moles as neoplasias apresentaram a maior ocorrência (30,15%), seguidas das neoformações cutâneas ou de anexos não neoplásicos (17,46%), neoformações cutâneas sem diagnóstico (7,94%), distocia (7,94%), fístula de papo (7,94%), hérnia abdominal (4,76%), sinusite (4,76%), gangrena de extremidade de membros (3,17%), perfuração de esôfago (3,17%), prolapso de cloaca (3,17%), "Necrose avascular de dígito" (1,59%), ferida na região da quilha (1,59%), perfuração de cavidade celomática (1,59%), neoformação em cavidade celomática sem diagnóstico (1,59%), corpo estranho em trato gastrointestinal (1,59%) e otite (1,59%). A distribuição das afecções cirúrgicas segundo as espécies acometidas mostrou o "grupo dos papagaios", representado em sua maioria por espécies do gênero Amazona, como prevalente. O conhecimento das afecções cirúrgicas e espécies de aves mais acometidas acrescentam informações para aqueles que já atuam nesta área e servem como indicador de estudo para futuros cirurgiões de aves.

Abstract:
The extinct dromornithids, gastornithids and phorusrhacids are among the most spectacular birds to have ever lived, with some giants exceeding 500 kg. The affinities and evolution of these and other related extinct birds remain contentious, with previous phylogenetic analyses being affected by widespread convergence and limited taxon sampling. We address these problems using both parsimony and tip-dated Bayesian approaches on an expansive taxon set that includes all key extinct flightless and flighted (e.g. Vegavis and lithornithids) forms, an extensive array of extant fowl (Galloanseres), representative Neoaves and palaeognaths. The Paleogene volant Lithornithidae are recovered as stem palaeognaths in the Bayesian analyses. The Galloanseres comprise four clades inferred to have diverged in the Late Cretaceous on Gondwana. In addition to Anseriformes and Galliformes, we recognize a robust new clade (Gastornithiformes) for the giant flightless Dromornithidae (Australia) and Gastornithidae (Eurasia, North America). This clade exhibits parallels to ratite palaeognaths in that flight presumably was lost and giant size attained multiple times. A fourth clade is represented by the Cretaceous Vegavis (Antarctica), which was strongly excluded from Anseriformes; thus, a crucial molecular calibration point needs to be reconsidered. The presbyornithids Wilaru (Australia) and Presbyornis (Northern Hemisphere) are robustly found to be the sister group to Anatoidea (Anseranatidae + Anatidae), a relatively more basal position than hitherto recognized. South America's largest bird, Brontornis , is not a galloansere, but a member of Neoaves related to Cariamiformes; therefore, giant Galloanseres remain unknown from this continent. Trait analyses showed that while gigantism and flightlessness evolved repeatedly in groups, diet is constrained by phylogeny: all giant Galloanseres and palaeognaths are herbivores or mainly herbivorous, and giant neoavians are zoophagous or omnivorous.

Abstract:
Описаны миграционные пути дикой самки серого гуся Anser anser L. (Anserifonnes), помеченной нелетным птенцом, из гнездовой группировки, размножающейся на Веселовском водохранилище (47°06'30" с.ш., 40°54'47" в.д., долина р. Западный Маныч). Установлено, что трижды с 2015 по 2018 г. самка зимовала на юге Западного Предкавказья: на Краснодарском (44°59'36" с.ш., 39°17'38" в.д.) и Варнавинском водохранилищах (47°06'30" с.ш., 40°54'47" в.д). Впервые получено прямое доказательство преждевременной и реверсивной миграции серого гуся во время зимовки первого года жизни по данным индивидуального мечения GPS-GSM-трансмиттером. Для анализа причин такой миграции изучена динамика погодных условий в январе и феврале 2016 г. (зимовка первого года жизни меченого гуся) в Западном Предкавказье. Установлено, что в южной части Прикубанской низменности в январе и феврале 2016 г. были более комфортные погодные условия по сравнению с районом происхождения (Весёловское водохранилище), где оставалась на зимовку часть гнездовой популяции серого гуся, и областью миграционной стоянки (46°00' с.ш., 38°07'30" в.д., Приморско-Ахтарские плавни). В целом январь и февраль характеризовались положительными среднемесячными температурами в районе зимовки и были теплее на 4° по сравнению с областью размножения, а ветры в предгорьях Кавказа были существенно слабее, чем севернее. В середине зимовки, в январе 2016 г., после резкого продолжительного потепления в районе зимовки годовалая самка предприняла попытку миграции на север Восточного Приазовья через миграционную остановку в Приморско-Ахтарских плавнях. Формирование неблагоприятных погодных условий (резкое понижение температуры до отрицательных величин, сильный ветер северо-восточного направления, снегопад) в северной части Предкавказья привело к возвращению гуся обратно, в район зимовки. Было показано, что нестабильная погодная обстановка в январе 2016 г. обусловила перемещения серого гуся в среднем на большие расстояния (6,0 ± 1,1 км) по сравнению с кочевками в следующем месяце - феврале (4,1 ±1,4 км). В другие годы эта самка не предпринимала попыток миграции на север в середине зимовки. Распределение дистанций перемещения особи в январе достоверно изменялось в разные годы и было самым значительным во время первой зимовки. Мы объясняем это тем, что сложившиеся погодные условия на юге Прикубанской низменности в январе 2016 г. могли послужить триггером такого миграционного поведения молодой птицы, а неблагоприятные погодные условия на трассе ее движения привели к реверсивной миграции в место зимовки.

Abstract:
El Museo de La Plata posee una extensa variedad de colecciones, preservando alrededor de 3000000 de ejemplares, los cuales revisten importancia cultural y científica. Entre ellas, la colección de aves cuenta con una gran diversidad de pieles de estudio (15000 piezas), esqueletos (4000), ejemplares armados y en exhibición (600), nidos (700) y huevos. Aquí damos a conocer la abundancia y diversidad de huevos de aves no Passeriformes de la colección de Ornitología del Museo de La Plata. Los huevos están depositados en cajas plásticas con vellón de silicona y están incorporados en una base de datos estandarizada. Esta colección posee 2736 huevos de aves no Passeriformes, con registros a partir de 1887. Solo el 7,8% (n = 215) de los huevos de esta colección están determinadas a nivel de familia o género, el resto a nivel de especie. El 94,7% (n = 2588) de los huevos provienen de diversas provincias de Argentina (siendo las más representadas Buenos Aires y Tucumán), el 3% de Antártida (n = 82) y el 2,3% restante a especies de otros continentes (n = 63). La colección posee huevos de Europa (n = 82), de África (n = 6), Oceanía (n = 5), América del Norte (n = 3) y Asia (n = 2). Están representados 24 órdenes, 48 familias y 176 especies de aves, siendo los más abundantes los Anseriformes (16%), Charadriiformes (14%), Gruiformes (14%) y Falconiformes (11%). Con esta contribución pretendemos difundir el material depositado en la colección oológica del Museo de La Plata, ya que creemos que es importante como material de base para futuros estudios científicos y de divulgación.

Abstract:
AbstractAmong cavity-nesting birds, a distinction can be made between excavators, which dig their own cavities, and cavity-adopters, which nest in pre-existing cavities. Historically, these two types of species have been grouped together as “cavity-nesters,” but it has become clear that the two nesting habits are associated with very different suites of life-history characters. This paper tests the hypothesis that cavity-adopters differ from excavators and other nest-building species in their propensity to evolve colonial breeding. Because of their dependence on pre-existing cavities, cavity-adopters presumably have less control than excavators over the location of their nests, and this could limit their ability to nest near conspecifics. A literature survey of the nesting behavior of 842 species in 17 bird families shows that coloniality almost never occurs in species that are obligate cavity-adopters. A phylogeny-based comparative analysis of nesting behavior in the Anseriformes indicates that in this group, colonial breeding has evolved less frequently in lineages of cavity-adopters than would be expected by chance. Together, this evidence supports the hypothesis that colonial breeding systems are unlikely to evolve in lineages of cavity-adopters.Evolución de la Colonialidad en Aves que Nidifican en CavidadesResumen. Las aves que nidifican en cavidades pueden dividirse en dos grupos: las especies excavadoras, que construyen sus propias cavidades, y las no-excavadoras, que nidifican en cavidades pre-existentes. Históricamente, estos dos tipos de especies han sido agrupadas colectivamente como aves que anidan en cavidades, pero estudios recientes demuestran que los dos tipos de nidificación están asociados con diferentes caracteres de sus historias de vida. En este estudio se pone a prueba la hipótesis que especies no-excavadoras difieren de las excavadoras y de otras especies que construyen nidos en cuanto a su propensión a evolucionar hábitos de reproducción colonial. Debido a que dependen de cavidades pre-existentes, las especies no-excavadoras presumiblemente tienen menos control que las excavadoras sobre la ubicación de sus nidos, y esto podría limitar su habilidad para nidificar cerca de otros miembros de su especie. Una revisión bibliográfica sobre el comportamiento de nidificación de 842 especies pertenecientes a 17 familias demuestra que casi nunca se observa colonialidad en especies que obligatoriamente utilizan cavidades pre-existentes. Un análisis comparativo utilizando una filogenia y datos del comportamiento de nidificación de miembros del orden Anseriformes indica que la colonialidad ha evolucionado con menor frecuencia de lo esperado al azar en linajes de especies no-excavadoras que utilizan cavidades. En conjunto, estos datos apoyan la hipótesis que los sistemas de nidificación colonial tienen baja probabilidad de evolucionar en linajes de no-excavadoras que anidan en cavidades.

Abstract:
Talpanas lippa is described as a new genus and species of waterfowl from Kauai, Hawaiian Islands, that is unlike any other known member of the order. It is characterized by a short, stout tarsometatarsus and a braincase that is shallow and wide relative to its length with very small orbits. In comparison with extant species, the optic foramen of Talpanas is remarkably small whereas the maxillo-mandibular foramen, which is the exit point of the trigeminal nerve, is grossly enlarged. Relative to skull length and foramen magnum area, the maxillo-mandibular foramen is one order of magnitude larger in cross-sectional area than that of extant Anseriformes. We conclude that Talpanas had reduced visual abilities, as reflected externally by its small orbits and optic foramen, and a grossly hypertrophied trigeminal foramen. Taken together, this suggests that Talpanas may have been more heavily reliant upon somatosensory (tactile) cues for foraging than any living species of bird. Pectoral elements are unknown, but the evident lack of keen eyesight suggests that the species was flightless, as were many other insular waterfowl.

Abstract:
PunatsangChhu in Wangduephodrang 27.486°N 89.899°E (1,273m) is one of the largest rivers and an important zone in Bhutan for resident and migrant water birds. It is the expanse where the diverse birds are seen on a stretch between 27.462°N 89.901°E and 27.579°N 89.867°E (Tobgay 2017). Large numbers of winter migratory water birds in Bhutan have been found in this location (Spierenburg 2005). Common Goldeneye Bucephala clangula was first sighted on Saturday, 5th of January, 2019 along PunatsangChhu 27.512657’N 89.887610’E at the elevation of 1142meter above sea level in the morning but couldn’t capture photo and more over mistreated it to be some other common water birds. However, until on 8th of January, 2019, it was a success to have photographed while it was foraging alone at the sand extraction sites at around 12:30 hours in the evening. The duck was observed diving simultaneously under water foraging at the time of sighting. It was then photographed with the help of DSLR camera and kit lens 55–300 mm until it flew away to other side of the river.

Abstract:
The present study comprises the biodiversity of birds in Gorewada International bio-park situated at north-west of Nagpur city with geographical location 21°11′N 79°2′E and a good habitat for avian biodiversity. Bird watching and recording were done from March 2011 to February 2014, in the morning and evening hours during Sunday and holidays. 190 species belonging to 128 genera, 51 families and 17 orders (Podicipediformes, Pelecaniformes, Ciconiiformes, Anseriformes, Falconiformes, Galliformes, Gruiformes, Charadriiformes, Columbiformes, Psittaciformes, Cuculiformes, Strigiformes, Caprimulgiformes, Apodiformes, Coraciiformes, Piciformes and Passeriformes) were recorded. The order Passeriformes is the largest order belonging to 20 families and 75 bird species. Out of total bird species, 89 (46.84%) are resident, 77 (40.53%) are resident migrant and 24 (12.63%) are migratory species. Forest region of this bio-park provides heterogeneity in vegetation and lake is rich in aquatic fauna and other food for avian species. Therefore, this region is well suitable for feeding, resting and roosting site for aves. The report obtains information regarding resident birds, migratory birds and resident migratory birds of Gorewada bio-park.

Abstract:
DNA barcoding is extensively used as a species identification and delineation tool. The aim of this study was to generate a barcode profile for mitochondrial cytochrome c oxidase subunit 1 (COI) in the Philippine Duck Anas luzonica, a dabbling duck species endemic to the Philippines that is classified as ‘Vulnerable’ by the International Union for Conservation of Nature (BirdLife International 2016). COI barcodes were successfully obtained using muscle tissue samples from 46 A. luzonica individuals confiscated from illegal hunters in Pantabangan, Nueva Ecija. Analysis of TrN+Γ+I distances among the Anas luzonica COI sequences and those of 25 other Anas species revealed that COI barcodes cannot generally delineate hybridizing species. While Anas luzonica was differentiated from other species it is known to hybridize with and formed a monophyletic group in the neighbor-joining tree generated, sampling from areas of sympatry is needed since individuals were obtained from only one sampling site. The population structure of the Anas luzonica population was also examined using mitochondrial DNA control region and COI sequences. The population had high haplotype diversity and low nucleotide diversity, an indication that a bottleneck event had occurred, which is likely due to extreme hunting pressures and habitat destruction. The population under study exhibited high genetic diversity. Given that the samples for this study came from a single locality, sampling from other localities is required to determine whether other populations are facing the risk of reduced fitness (inbreeding depression).
