Living on the Edge: Juvenile Foraging and Adult Breeding Ecology of an Aerial Top Predator in Urban Environments

Ecology and Evolution, Volume 16, Issue 2, February 2026.
We analyzed a combination of GPS tracking data and nest‐monitoring data from an urban population of an opportunistic rodent specialist, the Common Buzzard (Buteo buteo), to analyze how raptors utilize urban landscapes. Buzzards occupied even extreme habitats such as residential areas for foraging and breeding and benefit from lucrative foraging ...

American kestrel population trends and vital rates at the continental scale

Ecosphere, Volume 17, Issue 2, February 2026.
Abstract The American kestrel (Falco sparverius, hereafter referred to as kestrel) has declined across much of its North American range since at least the mid‐1960s. Kestrel population dynamics have been explored through a multitude of local studies and two broad reviews of available data. Across large geographic extents, however, the demographic cause(

Flooding and a complex predator community drive American oystercatcher nest and chick survival in Virginia

The Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
We investigated low American oystercatcher (Haematopus palliatus) productivity in the Virginia barrier islands, which historically supported high oystercatcher reproductive success. We found that chick survival was lower than nest survival, and that management may need to adapt to address evolving threats from coastal flooding and a multi‐guild ...

The Life of Brian … and David: Two Flying‐Foxes' Contribution to Science

Ecology and Evolution, Volume 16, Issue 1, January 2026.
This Nature Note examines whether thumb bands and surgically implanted temperature transmitters adversely affect the welfare of free‐living grey‐headed flying‐foxes. Long‐term monitoring and necropsy findings from two males, Brian and David, suggest negligible impacts of these procedures on individual welfare. Although based on only two cases, the rare

Returning neighbors: eastern wild turkey (Meleagris gallopavo silvestris) occupancy in an urban landscape

The Journal of Wildlife Management, Volume 90, Issue 1, January 2026.
We found that urban wild turkey had a higher probability of occupying a site if it was farther from roads and trails, closer to water, had more available habitat at finer spatial scales, or had lower mean tree height at larger spatial scales Abstract Once extirpated from most of its range because of overharvest and habitat loss in the early 1900s, the ...
