As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Penguins' calls are influenced by their habitat


Date:  November 1, 2017

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.
