Breeding biology of Neotropical Accipitriformes: current knowledge and research priorities

open access: yesRevista Brasileira de Ornitologia, 2018
Despite the key role that knowledge on breeding biology of Accipitriformes plays in their management and conservation, survey of the state-of-the-art and of information gaps spanning the entire Neotropics has not been done since 1995. We provide an updated classification of current knowledge about breeding biology of Neotropical Accipitridae and define

Overwintering and Resident Birds in Qatar: Explorations With DNA Barcoding

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
We obtained DNA barcodes for 115 birds (34 species, 12 orders) in Qatar, a country with no previous barcode sequence data for wild birds. We provide insights on locally breeding species and overwintering migrants. ABSTRACT Genetic research is unevenly distributed across the globe, with most research done in temperate zones.

Global patterns of colouration complexity in the Paridae: Effects of climate and species characteristics across body regions

open access: yesJournal of Animal Ecology, Volume 94, Issue 7, Page 1461-1473, July 2025.
Variation in colour complexity in the Paridae is linked to climate, climate variability and several biotic factors. The strength of the associations is patch specific. Variables related to resource competition are more strongly associated with colour complexity of the head and breast than with that of the back and wing.

Additional file 5 of Avian haemosporidian parasites of accipitriform raptors

open access: yes, 2022
Additional file 5: Fig. S4. Bayesian inference tree of CytB lineages (474 bp) belonging to the genus Haemoproteus. Bayesian posterior probabilities and Maximum likelihood bootstrap values are indicated at most nodes. The sequences of the H. elani clade were used to root the tree.

Molecular screening for Sarcocystidae in muscles of wild birds from Brazil suggests a plethora of intermediate hosts for Sarcocystis falcatula

open access: yesInternational Journal for Parasitology: Parasites and Wildlife, 2022
The genus Sarcocystis and the species Toxoplasma gondii are the most prevalent sarcocystid organisms found in birds. Molecular phylogenies based on the first internal transcribed spacer of the ribosomal coding DNA (ITS1) have been widely used to identify

Avian influenza overview March–June 2025

open access: yesEFSA Journal, Volume 23, Issue 7, July 2025.
Abstract Between 8 March and 6 June 2025, 365 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (167) and wild (198) birds across 24 countries in Europe. HPAI A(H5N1) virus detections were predominant and mainly located in western, central and south‐eastern Europe.

Filling the distribution gaps of two species of Accipiter Brisson, 1760 (Aves, Accipitriformes) in northeastern Brazil [PDF]

open access: yesCheck List, 2019
We present new records of Gray-bellied Hawk, Accipiter poliogaster (Temminck, 1824), and Rufous-thighed Hawk, A. striatus erythronemius (Kaup, 1850), from northeastern Brazil and review the occurrence of these species in this region. While A.

Assessment of a Social Media‐Based Method for Determining Raptor Diet

open access: yesEcology and Evolution, Volume 15, Issue 6, June 2025.
This study mined social media as a citizen science method to reduce the time burden and biases associated with recording accurate diet information for predators. In total, 1985 prey observations were recorded of two Australian coastal raptors and were used to produce diet profiles that were compared by region, social media platform, and against other ...

Effects of wind farms on raptors: A systematic review of the current knowledge and the potential solutions to mitigate negative impacts

open access: yesAnimal Conservation, Volume 28, Issue 3, Page 334-352, June 2025.
Our review of 195 studies highlights the consensus on raptors’ avoidance behavior and population decline post‐wind farm installation, emphasizing the significant risks posed by mountaintop wind farms to soaring raptors. Adult raptor mortality, particularly among endangered species, and the elevated collision risks faced by young individuals underscore ...
