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 ...

Do Energetic Challenges Mimicking Missed Foraging Encourage Torpor Use by a Neotropical Bat?
Biotropica, Volume 58, Issue 2, March 2026.We experimentally tested whether Merriam's long‐tongued bat (Glossophaga mutica), a Neotropical nectarivorous species, uses heterothermy in response to reduced energy intake. We found that energetically challenged bats maintained subcutaneous temperatures significantly closer to roost temperature during the daytime inactive period.
