A national assessment of waterbird hunting in coastal wetlands of Suriname, South America

Conservation Science and Practice, Volume 8, Issue 5, May 2026.
We examined waterbird harvest levels in Suriname using hunter survey data from 2006 and 2016. The analysis showed a significant decline in the average harvest per hunter over the decade, except for blue‐winged teal and migratory shorebirds. However, the sustainability of current harvest levels remains uncertain, underscoring the need for a national ...

Relationships between bird morphology and prey selection in two sympatric Great Cormorant Phalacrocorax carbo subspecies during winter.

, 2009
International audienceVariation in bird morphology (notably sex size dimorphism) has been suggested to contribute to differences in food use between individuals. We explore the hypothesis of food partitioning (diet overlap and prey size selection) in two

Abundance, Distribution and Population Trends of Waterbirds in the Usangu Wetland: A Biodiversity Hotspot Threatened by Human Activities

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Waterbirds play vital ecological roles in wetland ecosystems. This study reports variations for 34 species of waterbirds across study sites of Usangu Wetland abundance with distribution bias in rice farms. The waterbird population trend is declining because of habitat alteration and hunting hence conservation measures should be taken to enhance ...

CNN Architectures for Large-Scale Audio Classification

, 2017
Convolutional Neural Networks (CNNs) have proven very effective in image classification and show promise for audio. We use various CNN architectures to classify the soundtracks of a dataset of 70M training videos (5.24 million hours) with 30,871 video ...

Adaptation in the Avian Middle Ear—The Columellar Annular Ligament in Aquatic and Diving Birds

Journal of Morphology, Volume 287, Issue 4, April 2026.
The size of the columellar footplate relative to the oval window shows striking variation across species: it fits snugly within the oval window in, for example owls (left), but considerably smaller than the oval window in diving taxa such as cormorants (right).
