Known Breeding and Wintering Sites of a Bicknell's Thrush

摘要

We banded a Bicknell's Thrush (Ca- tharus bicknelli) on its Vermont breeding home range and recaptured the same bird less than six months later on its winter territory in the Dominican Republic. The encounter provides an rare link between known breed- ing and wintering sites for a Nearchtic-neotropical mi- gratory passerine. This individual was documented to return to its breeding site two successive summers and probably reoccupied the same territory during the wi- ter following its initial recapture. We believe that the small breeding and wintering range of the Bicknell's Thrush, its specialized habitat requirements, and its Documented site fidelity increase the species' vulner- Ability to habitat loss.
