External structures at the nest‐site predict asymmetric architecture of nests in a mud‐building bird
Ibis, Volume 168, Issue 4, Page 1696-1703, October 2026.In the animal kingdom, nests are essential structures and textbook examples of extended phenotypes. However, the relationship between builders, nest traits and the nest‐site remains poorly understood. We indirectly examine whether structures in the nest‐site influence nest‐building behaviour, specifically focusing on their effect on nest architecture ...

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 ...

Éxodo de dormideros por los tordos renegridos (Molothrus bonariensis)
, 1993 Algunas especies de aves coloniales se dispersan de sus dormideros nocturnos en flujos continuos mientras que otras lo hacen en una serie de éxodos interrumpidos por un lapso más o menos regular. Discutimos el patrón de dispersióndel tordo renegrido (Molothrus bonariens is) de dormideros urbanos en la ciudad de Paraná, Entre Ríos.
