About the Blackburnian Warbler

The Blackburnian warbler is a small New World warbler. They breed in eastern North America, from southern Canada, westwards to the southern Canadian Prairies, the Great Lakes region and New England, to North Carolina. They are migratory, wintering in southern Central America and South America, and are very rare vagrants to western Europe. The common name honors the English botanist Anna Blackburne.
