Predation, Climate and Species Traits Interact to Shape Global Patterns of Avian Nest Architecture
Global Ecology and Biogeography, Volume 35, Issue 6, June 2026.ABSTRACT Aim Bird nest structures are critical for reproductive success and vary widely across species. However, the ecological and evolutionary drivers behind enclosed nests (domes and cavities) remain unclear, with previous studies yielding conflicting results.

Female vocalizations predict reproductive output in brown-headed cowbirds (Molothrus ater).
PLoS ONE, 2018 Pair bonds are often maintained through the reciprocal and coordinated exchange of communicative signals. The ability to recognize and appropriately respond to a partner's signals will define a pair's ability to reproduce.

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 ...

Atypical song reveals spontaneously developing coordination between multi-modal signals in brown-headed cowbirds (Molothrus ater). [PDF]
PLoS ONE, 2013 The courtship and dominance behavior of brown-headed cowbirds (Molothrus ater) consists of a multi-modal display, including song as well as postural and wing movements. The temporal sequences of the acoustic and the visual display are coordinated.

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.
