North American Migratory Bird Count
May 8, 2004
Boyce Mayview Park, Upper St. Clair, Allegheny County, Pennsylvania
This year’s North American Migration Count in Boyce Mayview Park established a new benchmark for the count, surpassing the previous high in 2002 by 21 species. Also notable, the group birding in Boyce Mayview Park counted six species that were not found elsewhere in Allegheny County: Pine Warbler, Northern Harrier, Hermit Thrush, Woodcock, Pied-billed Grebe and Bobolink. “The park didn’t hold more birds that day — this was just good birding,” remarked Bill Judd, the count coordinator. Bill hopes next year’s count will be even better.
The results of the count are combined with other counts in Allegheny County and Pennsylvania and are forwarded to the National Audubon Society to be included in their international spring migration count. This information is useful in helping determine bird population changes, geographic shifts and changes of migratory patterns of species.
