Audubon Christmas Bird Count
|
The Audubon Christmas bird count has been in existence since 1897. The South Mountain Audubon Society and friends participate in the count every year since the society was founded in 1981.
The count area is a circle with a radius of 7 miles centered near Knoxlyn, PA as shown on the following map.
The count figures for recent years are given below; the complete counts (since 1981) are available as a downloadable spreadsheet. The trends in the counts are shown on a separate page.
CW - observed during the count week rather than the day of the count.
