The Biogeography of Great Salt Lake Halophilic Archaea: Testing the Hypothesis of Avian Mechanical Carriers

open access: yesDiversity, 2018
Halophilic archaea inhabit hypersaline ecosystems globally, and genetically similar strains have been found in locales that are geographically isolated from one another.

Two Capture Techniques for American White Pelicans and Great Blue Herons

open access: yesColonial Waterbirds, 1998
-We describe two techniques for capturing American White Pelicans (Pelecanw erythmhynchos), Great Blue Herons (Ardea harodias), and other large wading birds in aquatic habitats. One technique involved using #3 padded jaw leghold traps modified by replacing both factory coil springs with weaker #1.5 coil springs, to reduce the closing force of the jaws,

Ecomorphological Analysis of the Bird Lumbosacral Organ in an Evolutionary Context. [PDF]

open access: yesJ Morphol
Our geometric morphometric analysis of 36 bird species reveals locomotor‐linked adaptations in the lumbosacral organ (LSO). Perching birds show proportionally larger LSOs, while aquatic species exhibit elongated vertebral canals. We demonstrate strong pelvic‐LSO covariation and significant phylogenetic signals, supporting the LSO's role in equilibrium ...

The influence of rivers on seabird foraging ecology

open access: yesBiological Reviews, EarlyView.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

Advancing understanding of the taxonomy and diversity of the genus Contracaecum in the great white pelican (Pelecanus onocrotalus)

open access: yesParasitology Research, 2022
Despite the wide distribution and health importance of anisakids of the genus Contracaecum, epidemiological data on their occurrence in definitive bird hosts are scarce, particularly from certain parts of the world that represent important wintering sites or migration stopovers for different bird species.

Big Bird: A global dataset of birds in drone imagery annotated to species level

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Drones are a valuable tool for surveying birds, but manually detecting and identifying birds in drone images is costly. We assembled a diverse dataset of 23 865 images of birds captured with 21 different drones across 11 countries. We labelled 4824 of these images, detailing the location, species, posture category, age category, and sex of 49 990 birds

Citizen science reveals host‐switching in louse flies and keds (Diptera: Hippoboscidae) during a period of anthropogenic change

open access: yesMedical and Veterinary Entomology, EarlyView.
A study of louse flies in the United Kingdom, Isle of Man, and Ireland found 212 different interactions between Hippoboscidae and their hosts, of which 70 were previously unrecorded. No louse flies were found on aquatic species of birds. Host‐switching to gulls (Laridae) has occurred during a period in which these species have started relying on ...

X‐ray computed tomography study of terrestrial analog cores in preparation for Mars sample return

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 3, Page 405-426, March 2026.
Abstract Mars Sample Return (MSR) is expected to transform planetary science by providing unprecedented access to pristine Martian material. Initial characterization in the sample receiving facility (SRF) will rely on nondestructive techniques such as X‐ray computed tomography (XCT) to document the condition, distribution, and internal features of ...

A theoretical model of flock formation to understand trade‐offs between cooperation and competition

open access: yesEcosphere, Volume 17, Issue 2, February 2026.
Abstract Migratory birds often form flocks during spring migration and compete for territories once they arrive at breeding sites. Understanding the emergence and structure of these flocks has important implications for avian ecology and conservation, as flocking can influence migration success, resource distribution, and population resilience. In this

Evidence of High Pathogenic Avian Influenza H5N1 Clade 2.3.4.4b Among Poultry in Ghana From 2021 to 2022

open access: yesVeterinary Medicine and Science, Volume 12, Issue 1, January 2026.
Ghana experienced outbreaks of highly pathogenic avian influenza A H5N1 among poultry from 2021 to 2022. Analysing poultry, pigs, and environmental samples showed H5N1 prevalence of 2.36% (63/2640) among poultry only. The clade 2.3.4.4b virus showed mammalian adaptive motifs in haemagglutinin, emphasising the need for ongoing genomic surveillance among
