From the Audubon site FAQ "The Christmas Bird Count is a long-standing program of the National Audubon Society. It is an early-winter bird census, where volunteers follow specified routes through a designated 15-mile (24-km) diameter circle, counting every bird they see or hear all day. It's not just a species tally - all birds are counted all day, giving an indication of the total number of birds in the circle that day. All individual CBC's are conducted in the period from 14 December to 5 January (inclusive dates) each season, and each count is conducted in one calendar day."
The current Christmas Bird Count (CBC) data for State College (or any other region and circle in the western hemisphere) is available on the Audubon web site by clicking on "Current Year's Results", selecting a region, and then selecting a circle. If you do that for the region Pennsylvania and the circle State College, you will see the results from the most recent State College CBC.
Similarly, you can view the data for any year for any region and circle by going to Audubon web site and clicking on Historical Results and following the instructions. For State College, you can choose a single year or a range of years from 1940 to the present. The result is a web page with a table of data for the range you specified.
The species seen during a State College CBC are about the same from year to year. The State College Christmas Bird Count for 1998 is just one representative year, and is included here because the list is more immediately available than by going to the Audubon site.
All of the State College CBC data from 1940 to the present may be downloaded from our web site as a single file (see Download List below). The data is a Microsoft Excel spreadsheet to view the data, you will need Excel or software that can interpret data in Excel format. The data here should be identical to the data on the Audubon web site.
The maps of the State College CBC circle (350KB) and Bald Eagle State Park (901KB) CBC circle show the boundaries of the count circles. Note that some browers (e.g., Firefox) display a smaller image which you can expand by clicking on the image.
The Christmas Bird Count Report Form (see Download List below) for both State College and Bald Eagle State Park is available for downloading as a Microsoft Word document with two pages. With a printer with duplexing, it should print a single page front and back. On a typica non-duplexingl home printer, you can print page 1, then flip the page over and print page 2.
Rare or extremely infrequent species require a few extra supporting details by filling out a Rare Bird Report (see Download List below) and mailing to a local compiler. The compilers are listed on the Christmas Bird Count Report Form mentioned above.
