Identifying ACAP-listed Balearic from Manx and Yelkouan Shearwaters

Marcel Gil-Velasco and colleagues have published in this month in the journal British Birds on identifying the three small shearwaters that breed within Europe.

The paper’s abstract follows:

“Three medium-sized Puffinus shearwaters breed in Europe: Manx P. puffinus, Yelkouan P. yelkouan and Balearic Shearwaters P. mauretanicus.  These three, considered a single, polytypic species until relatively recently, can be difficult to identify in some situations, notably in a vagrant context.  This paper presents a detailed review of the plumage variability of the three taxa; combined with an understanding of structural differences and flight characteristics, this should provide a sound basis for the identification of problematic individuals.”
