Diversity, Abundance and Community Composition of Birds in Chitwan Annapurna Landscape, Central Nepal. [PDF]

Ecol Evol
Understanding bird diversity and composition is important for assessing survival, adaptability, and extinction risks. This study investigated bird species abundance, richness, seasonal diversity, and composition across habitats, seasons, and physiographic zones of Chitwan Annapurna Landscape (CHAL) from 2020 to 2021 using the point count method.

Annual report on surveillance for avian influenza in poultry and wild birds in Member States of the European Union in 2021. [PDF]

EFSA J, 2022
Abstract European Union (EU) Member States (MSs) are required to carry out surveillance for avian influenza (AI) in poultry and wild birds and notify the results to the responsible authority. In addition, Iceland, Norway, Switzerland and the United Kingdom (Northern Ireland) also implement ongoing surveillance programmes to monitor incursions of avian ...

A renewed glance at the Palearctic golden eagle: Genetic variation in space and time. [PDF]

Ecol Evol
In this study, we investigated the phylogeography, demographic history, and impacts of past population bottlenecks in Eurasian golden eagles. Using microsatellite loci and mitochondrial DNA, we discovered a north–south genetic gradient where Central Asia and Caucasus was a high genetic diversity region, and Northern Europe showed the opposite trend. We

Outdoor recreation alters terrestrial vertebrate scavenger assemblage and carrion removal in a protected Mediterranean wetland

Animal Conservation, Volume 26, Issue 5, Page 633-641, October 2023., 2023
We found that outdoor recreation alters the vertebrate scavenger assemblage and carrion removal. Larger scavenger species are most affected, especially raptors. Furthermore, human activities promote the presence of non‐native species in the ecosystem. Therefore, areas of restricted access are essential to preserve biodiversity and ecological processes ...

Collateral damage from agricultural netting to open‐country bird populations in Thailand

Conservation Science and Practice, Volume 4, Issue 11, November 2022., 2022
Nets are used across a wide variety of food production landscapes to control avian pests typically resulting in the death of entangled birds. Based on 1312 road‐survey transects, we documented 735 individuals of at least 45 bird species caught in nets and parallel cords, including many species not regarded as pests. We suggest imposing a ban on netting.

Sex, landscape diversity and primary productivity shape the seasonal space use of a migratory European raptor

Journal of Avian Biology, Volume 2022, Issue 10, October 2022., 2022
Intrinsic and extrinsic drivers shape the space use of wide‐ranging raptors. A large proportion of raptors are migrants that shift their activity ranges between summer and winter habitats, where they encounter different environmental conditions. Analysing the effects of intrinsic and extrinsic drivers on the space use in summer and winter habitats ...

A survey of the uncinate bone and other poorly known ossicles associated with the lacrimal/ectethmoid complex of the avian skull

The Anatomical Record, Volume 305, Issue 9, Page 2312-2330, September 2022., 2022
Abstract In several taxa of Neornithes (crown group birds), the lacrimal/ectethmoid complex exhibits small bones, the comparative osteology of which is poorly studied. Some of these ossicles—which are commonly known as uncinate bones (ossa uncinata or ossa lacrimopalatina)—were already described two centuries ago, but knowledge of their distribution ...

Birds as indicators of early Holocene biodiversity and the seasonal nature of human activity at WF16, an early Neolithic site in Faynan, Southern Jordan

Journal of Quaternary Science, Volume 37, Issue 6, Page 1148-1163, August 2022., 2022
Abstract Birds are useful indicators of biodiversity. Their bones have been used for reconstructing the local environments and seasonality of human activity at Epipalaeolithic and early Neolithic sites in south‐west Asia. We consider the bird bones from WF16, an early Neolithic settlement in southern Jordan, currently located in an arid environment ...

Hotspots in the grid: Avian sensitivity and vulnerability to collision risk from energy infrastructure interactions in Europe and North Africa

Journal of Applied Ecology, Volume 59, Issue 6, Page 1496-1512, June 2022., 2022
We identify the areas of Europe and North Africa that are most sensitive for the specific populations of birds for which sufficient GPS tracking data at high spatial resolution were available. We also map vulnerability hotspots where mitigation at existing EI should be prioritised to reduce collision risks.

Avian Diversity and Abundance of Taunsa Barrage Ramsar Site in Punjab, Pakistan

Journal of Zoological Systematics and Evolutionary Research, Volume 2022, Issue 1, 2022., 2022
The study of avian species diversity and abundance at the Taunsa Barrage Ramsar site was carried out from September 2019 to March 2020. Taunsa Barrage is an important wetland for international and local migratory birds, including waterfowls, waders, and long‐distance migrant avifauna.
