External structures at the nest‐site predict asymmetric architecture of nests in a mud‐building bird

Ibis, EarlyView.
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 ...
