Bird List: JOHN JAMES AUDUBON CENTER AT MILL GROVE


John James Audubon Center in Montgomery County, PA, was established in 1951 by the County Commissioners as an historic site and wildlife preserve.  In 1989, John James Audubon Center was designated as a National Historic Landmark by the Department of the Interior and the National Park Service. 

The old stone farmhouse on the east bank of the Perkiomen Creek is surrounded by approximately 214 acres of steep forested slopes, open meadows, and mowed lawns.  A tributary to the Schuylkill River, the Perkiomen Creek forms part of the Delaware Valley flyway through which a diversity of birds migrate twice each year.  In addition, about sixty species of birds have been found nesting on the property.

While 190 species of birds have been observed at the John James Audubon Center since 1953, several species have been seen here only once and may never appear again.  However, there is always the chance for recurrence or the establishment of a new record.  This list was last updated in 2008.
