Strong individual distinctiveness across the vocal repertoire of a colonial seabird, the little auk, Alle alle
For species maintaining long-term social bonds, particularly in complex networks such as dense colonies, vocal cues to identity can be crucial. Here, we investigated the vocal individuality within and across five call types of the little auk: a monogamous, colonial bird with a strong nest fidelity....
