Breeding-site fidelity and dispersal in isolated populations of three migratory passerines.

This article presents a study which investigated site fidelity and natal philopatry in three passerine species within an isolated patch of suitable habitat in European North of Russia. Researchers analyzed five years of Russian banding data on Booted Warbler, Whinchat and Yellow Wagtail. They discovered that the survival rate of the Yellow Wagtail was higher than that of the Whinchat and Booted Warbler. The study concludes that species-specific returning rates and annual fluctuation are defined by mortality and reproductive success.
