The International Audubon Migratory Bird Count

May 12, 2001

Boyce Mayview Park, Upper St. Clair, Allegheny County, Pennsylvania

Again this year, USC Citizens for Land Stewardship sponsored the Spring Migratory Bird Count on the Boyce Mayview Park property. There were three teams of observers who participated in the count. The weather was wet and rainy in the morning and much of the count was delayed until the weather broke. In spite of this, the count was successful. Sixty-seven species were counted on the property, and a total of 959 individual birds were counted. Our count had the only kestrel (seen near the Mayview barns) and the only wood ducks in Allegheny County. Chimney swifts were in great profusion. Tree swallows were competing with bluebirds for the bluebird boxes. Five species of warblers were counted. Indigo buntings, scarlet tanagers and Baltimore orioles all added a nice touch of color and some excitement to the day.

The results of this migratory bird count have been forwarded to the National Audubon Society and will 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.

Special thanks to CLS members, Vicky and Bill Judd, who coordinated and compiled this count.
