Sandhill Crane Roost Selection, Human Disturbance, and Forage Resources [PDF]

, 2016
Sites used for roosting represent a key habitat requirement for many species of birds because availability and quality of roost sites can influence individual fitness. Birds select roost sites based on numerous factors, requirements, and motivations, and

Diurnal habitat selection of migrating Whooping Crane in the Great Plains

Avian Conservation and Ecology, 2019
Available stopover habitats with quality foraging opportunities are essential for migrating waterbirds, including Whooping Crane (Grus americana). Several studies have evaluated habitats used by Whooping Crane for roosting throughout its migration ...

Climate‐related drivers of migratory bird health in the south‐central USA

Biological Reviews, Volume 100, Issue 3, Page 1272-1293, June 2025.
ABSTRACT Migratory birds are species of concern that play important ecological roles while also supporting recreational opportunities for the hunting and birdwatching public. Direct and indirect effects of climate variability, extremes, and change on migratory bird health manifest at the individual, population, species, and community levels.

Same‐sex partnerships in birds: a review of the current literature and a call for more data

Journal of Avian Biology, Volume 2025, Issue 3, May 2025.
Same‐sex sexual behaviour (SSB), encompassing actions such as courtship, pair bonding, and parenting between individuals of the same sex, has been observed across numerous taxa, including birds. Yet despite its widespread occurrence, SSB remains poorly understood, often dismissed as maladaptive or the result of errors in sex discrimination.

A Comparison of Approaches to Mitigate Hypothetical Bias [PDF]

We compare two approaches to mitigating hypothetical bias. The study design includes three treatments: an actual payment treatment, a contingent valuation (CV) treatment with a follow-up certainty question, and a CV treatment with a cheap talk script ...

Translocation experiment of taiga bean geese Anser fabalis provides evidence for oblique social learning of moult migration

Journal of Avian Biology, Volume 2025, Issue 3, May 2025.
While there is ample evidence supporting genetic control of migratory behaviour in short‐lived passerines, long‐lived social species have been assumed to rely solely on cultural inheritance of migratory routes. Evidence from experimental studies supporting this idea is scarce.

Avian influenza overview December 2024–March 2025

EFSA 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.

Benefit-Cost in a Benevolent Society [PDF]

How should benefit-cost analysis account for the value that benevolent individuals place on other people's pleasure from public goods? When adding up the benefits to be compared with costs, should we sum the private valuations, the altruistic valuations,
