Diversity, Distribution and Relative Abundance of Avian Fauna of Nansebo Forest, Southern Oromia, Ethiopia [PDF]

open access: yes, 2019
Birds are one of the components of biodiversity. Avian community studies are effective tools for monitoring a forest ecosystem. The status of birds in the present study areas is very little known.

Avian influenza overview December 2024–March 2025

open access: yesEFSA Journal, Volume 23, Issue 4, April 2025.
Abstract Between 7 December 2024 and 7 March 2025, 743 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (239) and wild (504) birds across 31 countries in Europe. HPAI A(H5N1) virus detections were predominant and mainly located in central, western and south‐eastern Europe.

Taxonomic status of Cyathostoma nematodes (Nematoda: Syngaminae) parasitizing respiratory tracts of birds of prey and owls in Europe and North America: how many species are there?

open access: yesHelminthologia, 2016
So far, the identity of Cyathostoma (Hovorkonema) nematodes collected from respiratory tracts of birds of prey (Accipitriformes, Falconiformes) and owls (Strigiformes) in Europe and North America is extremely inconsistent.

Divergent Importance and Geographic Patterns in Threats to Birds and Mammals in China

open access: yesDiversity and Distributions, Volume 31, Issue 2, February 2025.
ABSTRACT Aim Wildlife populations are continuing to decrease worldwide. Understanding the ranking and distribution of drivers of species declines is crucial to enable targeted actions to counteract major threats. However, few studies have assessed the relative importance and geographic distribution of threats to biodiversity in China, even for high ...

The Importance of Olfaction for Mixed Paternity in Birds

open access: yesEcology and Evolution, Volume 15, Issue 1, January 2025.
Olfaction can help individuals finding genetically compatible mates in many animals, while high levels of mixed paternity may reflect a reduced ability to evaluate a mate's profile against their own before mating. We tested this hypothesis by matching estimates of olfactory ability with mixed paternity for a broad range of bird species.

Broodmate aggression and life history variation in accipitrid birds of prey

open access: yesEcology and Evolution, 2019
Aggressive sibling competition for parental food resources is relatively infrequent in animals but highly prevalent and extreme among certain bird families, particularly accipitrid raptors (Accipitriformes). Intense broodmate aggression within this group

Vertebrate diversity and biomass along a recovery gradient in a lowland tropical forest

open access: yesBiotropica, Volume 57, Issue 1, January 2025.
Deforestation of tropical forests has resulted in large areas of secondary forests with the potential for biodiversity to re‐establish to levels usually found in old‐growth forests. This study shows that diversity and biomass of mammals and birds in regenerating forests can recover to old‐growth levels within a relatively short time.
