Summary:
Birds
use vocalizations to attract mates and defend territories. But while we know a
lot about how variations in vocalizations play out in songbirds, it's far less
clear how this variation affects birds such as penguins in which calls are
inherited. A new study examines the calls of Little Penguins and finds that
disparities in habitat, rather than geographic isolation, are the key driver of
variation in the sounds these birds use to communicate.
