Balancing moult, migration, and breeding in a long‐lived partially migrant raptor

open access: yesJournal of Avian Biology, Volume 2026, Issue 2, March 2026.
Moult, breeding, and migration are the three major life‐history events in the annual cycle of birds. All are energetically demanding processes that rarely overlap. In large raptors such as the Egyptian vulture Neophron percnopterus, completing a full moult may take more than one year, requiring birds to balance this process with other life‐cycle events.

Boom‐Bust Dynamics Drive Community‐Wide Dietary Structuring in Desert‐Dwelling Raptors

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
We investigated how boom‐bust productivity dynamics affected dietary structuring within raptor communities of an arid bioregion. We found that higher productivity was associated with high dietary overlap, lower niche breadth and greater foraging on small mammals; however, raptors that were nomadic exhibited greater specialisation regardless of ...

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

open access: yesEcology 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

open access: yesEcosphere, 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

open access: yesThe 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 ...
