Assortative flocking in crossbills and implications for ecological speciation.

Proceedings. Biological sciences - 22 Oct 2012

Abstract excerpt

How reproductive isolation is related to divergent natural selection is a central question in speciation. Here, we focus on several ecologically specialized taxa or 'call types' of red crossbills (Loxia curvirostra complex), one of the few groups of birds providing much evidence for ecological speciation. Call types differ in bill sizes and feeding capabilities, and also differ in vocalizations, such that contact...
