The Rufous-thighed Kite (Harpagus diodon) is an insectivorous migratory raptor that breeds in the Atlantic Forest, Cerrado, Chiquitanía, and Southern Andean Yungas and primarily overwinters in the ...

Hybridization is an important factor in bird evolution. Distinguishing between hybrids and phenotypically aberrant individuals of one of the parental species can be challenging. Here, we use DNA sequencing of loci on chromosomes 2 and Z and the mitochondrial DNA to establish the status of a putative hybrid Azure Tit Cyanistes cyanus X Blue Tit Cyanistes caeruleus caught in Belgium in 2021. The genotype at each of these loci was a perfect match to Blue Tit. We therefore conclude that the bird was a genetically pure Blue Tit, despite its plumage being intermediate between Azure Tit and Blue Tit. We suggest records of Pleske's Tit lacking DNA information should be treated with caution.

Due to their specific nesting requirements, cavity nesters are associated with a set of distinct habitat features. These characteristics can be shaped…

Birds are vulnerable to roadkill on highways. Understanding which factors may be associated with bird roadkill and the formation of roadkill hotspots is crucial for informing evidence-based mitigatio...

We studied the breeding biology of the Pelagic Cormorant (Urile pelagicus) around the Cape Peirce peninsula (58°32’N, 161°46’W) on the Bering Sea coast of Alaska, USA, in 1970 and 1973. Although ou...

Agricultural intensification has led to landscape changes and the extensive use of synthetic pesticides. Concurrently, a significant decline in biodiv…

The black stork, a vital wetland species, is threatened by habitat fragmentation, with this study using the MaxEnt model to identify key habitats in North China, Xinjiang, and the Yangtze River Basin...

As individual tracking devices and year-round genetic sampling become more accessible, research on the historically understudied nonbreeding period has exploded in the past decade. These studies are ...

Bird-window collisions are a principal source of mortality for free flying wild birds the world over. This report is an update on this important conservation issue for birds and people. Geographica...

The migration patterns of birds breeding at high latitudes have undergone major changes during the Holocene, as species expanded from small refugia following the last glaciation. Unique features of...

While often overlooked, permanent wetlands (e.g., lakes, rivers) can provide consistent stopover habitat for interior migrating shorebirds. We studied shorebird use and forage abundance during autu...

Estimating bird abundance is key to assess threats, and to prioritize conservation actions. However, few studies focus on this topic, particularly in …

Understanding how biodiversity is changing is key to improving conservation actions and informing decision-making. Urbanization is a Major driver of biodiv

European Journal of Wildlife Research - Nest predation is the leading cause of breeding failure in birds. A crucial aspect in predators’ foraging ecology is whether they depredate bird nests...

Foraging guild composition of mixed-species flocks were studied and compared between old-growth forests and selected human-modified landscapes with di…
