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. This review focuses on the effects of climate on migratory birds that spend part of their life cycles in the south-central USA. Although gaps in knowledge remain, prior studies provide a solid foundation to understand how climate affects migratory birds to inform management priorities and actions.

Bird-window collisions are a significant and growing threat to birds, but the issue is still understudied in many geographical areas and stages of the avian annual life cycle. The mountainous topography and numerous distinct biogeoclimatic zones along the Pacific coast of Canada and the United States may result in regional and seasonal differences in collision mortality and species vulnerability to collisions. We surveyed daily for evidence of bird-window collisions over six 21-day periods in fall, early winter, and late winter between 2019 and 2022 at a university campus in southwestern British Columbia, Canada, and assessed individual species' vulnerability to collisions by examining whether species-specific collision rates were disproportionate to their local abundance.

Accumulated evidence supports the critical role of migratory wild birds in highly pathogenic avian influenza virus (HPAIV) spread and evolution. An effective surveillance strategy to study HPAIV dispersal in wild birds and identify critical interfaces between wild birds and poultry on the landscape for potential interspecies transmission and virus evolution will be essential. This study integrates conditional likelihood with epidemiological research designs to investigate the risk of poultry farm outbreaks due to the introduction of HPAIV by migratory birds from the Taiwan citizen scientist dataset.

The tropical rainforest is one of the most biodiverse, productive, and complex terrestrial biomes in the world. Human-induced environmental changes increase the emergence and spread of vector-borne diseases. Ticks (Acari: Ixodida) are medically and veterinary important arthropods that infest a wide range of vertebrate hosts, including humans, and act as vectors of diverse pathogens, such as bacteria of the genus Rickettsia.

Avian influenza A viruses (AIVs) pose a significant pandemic threat due to their cross-species transmission potential. However, AIV surveillance at the critical "migratory birds-poultry-exposed population" interface remains limited. Between 2021 and 2024, we implemented a prospective One Health surveillance program around Nansi Lake, monitoring AIVs in migratory birds, poultry, and environmental samples, as well as serological investigations against representative AIVs among migratory birds or poultry-exposed subjects.

Migratory birds play a key role in the ecology of tick-borne pathogens, serving as both hosts for ticks and as potential carriers of a wide range of infectious agents that can affect wildlife, domestic animals, and humans. Their long-distance movements contribute to the dispersal of ticks and the pathogens they harbor, with potential implications for the emergence and spread of zoonotic disease. This study focuses on the prevalence of spp.
