Heard Bird Banders


Bird-banding contributes vital knowledge of habitat use. More than 25,000 birds have been banded at the Heard since the station’s establishment in 1978 and has provided information to evaluate habitat breeding quality. The station shares data with the U.S. Fish and Wildlife Service Bird Banding Laboratory (BBL) and participates in The Institute for Bird Populations (IBP) “MAPS” program (Monitoring Avian Productivity and Survivorship) by contributing our data to an international effort. MAPS measures reproduction on breeding grounds and combines data from the U.S., Canada and Mexico so scientists can determine global populations of most songbird species.
