Role of freshwater availability and terrestrial land‐cover change in the distribution of a declining, terrestrial, insectivorous bird

Conservation Biology, Volume 40, Issue 3, June 2026.
Abstract Insectivorous, Afro‐Palearctic migrant birds provide cross‐border ecosystem services, but many are declining rapidly. The complex life cycle of migrant birds makes their conservation difficult, but understanding where they spend time during the breeding season can help indicate where those actions will be most effective.

Las aves migratorias de América del Sur. Nuevas técnicas revelan información sobre su comportamiento [PDF]

, 2015
Aproximadamente la mitad de todas las especies conocidas de aves realizan desplazamientos migratorios, que son movimientos estacionales entre los lugares en que nidifican y se reproducen, en el verano, y aquellos en que pasan el invierno.

Microclimate refugia shape microclimatic niches and predict individual variability in post‐breeding migration in a partially migratory species

Journal of Animal Ecology, Volume 94, Issue 12, Page 2527-2541, December 2025.
The niche is characterized along a gradient of temperature and microclimate refugia. Individuals in breeding areas with low microclimate refugia availability are more likely to cover larger distances to post‐breeding areas, increasing exposure to risks.

Environmental and Geographic Conditions on the Breeding Grounds Drive Bergmannian Clines in Nightjars

Journal of Biogeography, Volume 52, Issue 10, October 2025.
ABSTRACT Aim To evaluate (1) whether three migratory nightjar species (Family Caprimulgidae) adhere to Bergmann's rule, (2) whether environmental factors on the breeding or wintering grounds determine body size, and (3) which mechanistic hypotheses best explain Bergmannian patterns in body size.

Immersion patterns alone can predict vessel following by albatrosses

Journal of Applied Ecology, Volume 62, Issue 8, Page 1831-1843, August 2025.
We demonstrate that seabird immersion patterns alone can detect high‐risk seabird‐vessel interactions, even in the absence of locational data for both seabirds and vessels. Our approach could allow for more comprehensive seabird bycatch risk assessments that quantify previously hidden seabird‐vessel interactions, such as those involving migratory life ...
