Ecology and Evolution, Volume 16, Issue 1, January 2026.Our findings regarding prey of breeding Cooper's Hawks in British Columbia and Wisconsin expand knowledge of their food habits and support the premise that seasonal agility of prey influences body size of nesting males. We deem it untenable to assume greater production of young at urban vs. rural nests based on proportion of avian prey use.

Seasonal variation in coprophagic foraging in alpine choughs Pyrrhocorax graculus
Journal of Avian Biology, Volume 2026, Issue 1, January 2026.Coprophagy, defined as the ingestion of faeces sourced from either self (autocoprophagy), conspecific animals (allocoprophagy), or heterospecific animals (heterocoprophagy), is recognized as a physiological adaptation that enhances nutritional intake and may contribute to gut microbiome stability.

Falcons reduce pre‐harvest food safety risks and crop damage from wild birds
Journal of Applied Ecology, Volume 62, Issue 12, Page 3327-3340, December 2025.In the absence of American kestrels, there are more birds in orchards. This leads to increased crop damage and more bird faecal contamination. Abstract Foodborne illness outbreaks have heightened pressures on growers to improve food safety, including mitigating possible threats from wildlife. Among wildlife, birds are particularly challenging to deter,

American crow (Corvus brachyrhynchos) thanatology [PDF]
, 2018 Thesis (Ph.D.)--University of Washington, 2018Given the complexity with which some animals respond to dead conspecifics, how and why non-human animals respond to dead conspecifics is of increasing scientific interest.

Effect of food patch discovery on the number of American Crows (Corvus brachyrhynchos) using a flight lane [PDF]
, 2014 In winter, American Crows (Corvus brachyrhynchos) move back and forth between night roosts and foraging sites along flight lanes. If communal roosts act as information centres, we would expect more birds to use a particular flight lane after discovery of

The distribution and abundance of the rook corvus frugilegus L. as influenced by habitat suitability and competitive interactions. [PDF]
, 1998 Rooks (Corvus frugilegus) are colonially breeding corvids found in most agricultural landscapes. Colonies in the County Durham area tend to be clustered at distances up to 500 m, but otherwise show little pattern in terms of spacing or size.
