Although we are included in the breeding range of the Prothonotary Warbler, only 7 have been banded at Powdermill.
The brilliant Prothonotary Warbler is very near the northern limit of its breeding range in Pennsylvania and is a rare and extremely locally distributed breeding bird within the state, nesting primarily (and sparingly) in extensive swamps in the glaciated northwestern corner and in the Piedmont region of the southeast.
The first Prothonotary Warbler was banded at Powdermill in April 1966, the second not until sixteen years later, in May 1982.
