Same as it ever was: Bird nest (a)symmetry?

Abstract

A recent publication analyzing data collected by citizen scientists on the rufous hornero (Furnarius rufus) revealed consistent among-individual variation in nest asymmetry (left vs. right entrance). We summarize this result and discuss: (1) nest building as a useful model system to study different questions, and, (2) what the repeatability found in the featured paper could reveal regarding nest-building decisions.
