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

open access: yesIbis, EarlyView.
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 ...

Osteology and arthrology of the ankle and tarsometatarsus of anoles (Iguania: Anolidae): not convergent with geckos but divergent from the ancestral iguanian condition

open access: yesJournal of Anatomy, EarlyView.
Geckos and anoline iguanid lizards are well‐known for their possession of adhesive toepads, which are generally regarded as being convergent structures. We show that the anatomical configuration of the foot in these two lineages differs markedly and that these differences likely relate to the contrasing ways they deploy their adhesive systems and ...
