The Status of North American Migrants in Central Amazonian Brazil

Abstract

We review the status of North American migrants in Amazonia and present recent records of the authors and co-workers. We report migration dates, maximum counts and new distributional information for 45 species. Included are the first Brazilian records of Piranga olivacea, the first Brazilian specimens of Contopus virens, and records of several shorebirds primarily restricted to coastal areas in South America that were previously unrecorded from inland Amazonia. Amazonia is south of the main wintering areas for most North American passerines; however, at least eight species winter primarily in Amazonia. Amazonia appears to be an important migratory route for many shorebirds, including major portions of the populations ofPluvialis dominica, Calidrisfuscicollis, and Calidris melanotos.
