A phylogeny of birds based on over 1,500 loci collected by target enrichment and high-throughput sequencing [PDF]

open access: yes, 2012
Evolutionary relationships among birds in Neoaves, the clade comprising the vast majority of avian diversity, have vexed systematists due to the ancient, rapid radiation of numerous lineages.

Spraying drones: efficacy of integrating an avian repellent with drone hazing to elicit blackbird flock dispersal and abandonment of sunflower fields

open access: yesWildlife Biology, EarlyView.
Multiple management strategies exist to combat bird damage to agriculture. We explored combining two tools, drones as frightening devices and an avian repellent, to assess effectiveness of an integrated method to deter large flocks on complex landscapes. We evaluated the ability of a spraying drone (DJI Agras MG‐1P) deploying Avian Control (i.e. active

Holding a wing horizontal: Roles for muscles of the pectoral girdle other than the main two flight muscles

open access: yesJournal of Anatomy, EarlyView.
This report explores which muscles of the pectoral girdle are employed to allow birds to hold their wings horizontally with a level aerofoil surface during a glide. Abstract Whilst many birds glide briefly with wings held horizontally, some species maintain this posture for extended periods during soaring.

Emergence, spread, and impact of high‐pathogenicity avian influenza H5 in wild birds and mammals of South America and Antarctica

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract The currently circulating high‐pathogenicity avian influenza (HPAI) virus of the subtype H5 causes variable illness and death in wild and domestic birds and mammals, as well as in humans. This virus evolved from the Goose/Guangdong lineage of the HPAI H5 virus, which emerged in commercial poultry in China in 1996, spilled over into wild birds,

Isotopic ordering in eggshells reflects body temperatures and suggests differing thermophysiology in two Cretaceous dinosaurs [PDF]

open access: yes, 2015
Our understanding of the evolutionary transitions leading to the modern endothermic state of birds and mammals is incomplete, partly because tools available to study the thermophysiology of extinct vertebrates are limited.

Introduced wild pigs affect the foraging ecology of a native predator as both prey and scavenger

open access: yesWildlife Biology, Volume 2026, Issue 1, January 2026.
Introduced species can disrupt trophic interactions by acting as novel predators, prey, or scavengers. Predicting the impacts of these disruptions can be integral to the conservation of native species and the maintenance of ecological function, but is challenging, especially for species involved in multiple trophic interactions.

Inventory of wildlife use of mortality pits as feeding sites: implications of pathogen exposure

open access: yesHuman-Wildlife Interactions, 2017
To better understand the use of mortality pits by wildlife and possible pathogen dissemination from the resulting wildlife contact in these areas, we used 8 camera traps on 4 mortality pits in Colorado from June to December 2014 to create a species ...

Soaring migratory birds avoid wind farm in the Isthmus of Tehuantepec, southern Mexico. [PDF]

open access: yesPLoS ONE, 2014
The number of wind farms operating in the Isthmus of Tehuantepec, southern Mexico, has rapidly increased in recent years; yet, this region serves as a major migration route for various soaring birds, including Turkey Vultures (Cathartes aura) and ...
