Effective range of auditory frightening devices based on hearing capabilities and antipredator responses of nuisance blackbirds

Wildlife Society Bulletin
A variety of acoustic strategies have been implemented to disperse wildlife from areas of human‐wildlife conflict. Propane cannons are a popular tool; however, their efficacy based on avian behavior has yet to be fully explored.

Using 3D printed eggs to examine the egg-rejection behaviour of wild birds [PDF]

PeerJ, 2015
The coevolutionary relationships between brood parasites and their hosts are often studied by examining the egg rejection behaviour of host species using artificial eggs.

Cowbirds use conspecific social information to detect host nests in the wild

Ibis, Volume 168, Issue 2, Page 799-804, April 2026.
Recent work shows that hosts of avian brood parasites use social information to increase egg rejection rates, but fewer studies explore how parasites themselves use such information to detect host nests in the wild. To determine whether wild Brown‐headed Cowbirds Molothrus ater use social information to detect host nests, we measured how individual ...

The presumption of sociality: Social learning in diverse contexts in brown-headed cowbirds (Molothrus ater). [PDF]

Journal of Comparative Psychology, 2002
Data are presented on social and vocal learning in cowbirds (Molothrus ater) housed in large aviaries and given more degrees of freedom than in conventional experimental studies. The studies show that social and vocal outcomes are facultative responses to social contexts.

A general framework for modeling pathogen transmission in co‐roosting host communities

Ecology, Volume 107, Issue 2, February 2026.
Abstract Cross‐species transmission of pathogens can be facilitated by frequent contact among wildlife. Cross‐species transmission is often driven by phylogenetic similarity between host species, but the role this plays when multiple host species co‐roost is unknown.

Twenty-two years of brood parasitism data do not support the mafia hypothesis in an accepter host of the Brown-headed Cowbird (Molothrus ater)

Journal of Field Ornithology, 2022
Most host species of the obligate brood parasitic Brown-headed Cowbird (Molothrus ater) accept foreign eggs and offspring despite the associated reproductive costs.

Does Seasonal Variation in Agility of Avian Prey Influence Body Size of Breeding Male Cooper's Hawks? And Comments on the Putative Influence of Avivory on Reproductive Output in Cities

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.

Conservation value of the umbrella species concept: Prairie Warblers receive few conferred benefits when habitat is managed for American Woodcock in Rhode Island, USA

Avian Conservation and Ecology
The umbrella species concept is a popular management approach based on the assumption that conserving one species benefits others, yet assessments beyond abundance often reveal mismatches in benefits to non-target species.
