I participate regularly in the Christmas Bird Count, but honestly never went to the Audubon Society count database. I won't make that mistake again. For Wichita Falls, the years from 1974 forward are posted and it is interesting to go back to see what was seen in previous years. I did go back to some of the counts that were part of the very first CBC and their information is not posted before 1984--I am not sure why ours is posted so much earlier. Perhpas we had a volunteer willing to update the information that other counts didn't have.
Thanks to Debra Halter who is the compiler for the Wichita Falls count, making sure all of the information is submitted and documentation put together for unusual species.
