Christmas Bird Count 2010: Hoover Reservoir

December 18, 2010, marked the 55th Anniversary of the Hoover Reservoir Christmas Bird Count.

Over the last decade the circle’s teams and their area of coverage stabilized and the effort to increase participation by feeder watchers has resulted in dramatic change. In the 1990’s the circle averaged about 62 species and 15 participants per count. The past decade saw these increase to averaging about 72 species and 30 participants per year.

The increased turnout is enabling us to give coverage to areas often left out in earlier years. Better participation and wider coverage are reflected by the numbers, 77 species in 2009 and 83 species in 2010. When I first became involved with the Hoover Reservoir circle in the early 1980’s the turnout was meagre, often single digits, and the coverage restricted to the west shore of the reservoir. Almost everyone wanted to hang close to the then compiler, an excellent birder and teacher. This omitted huge parts of the circle and the numbers were almost predictable before starting.

Tom Thomson was the compiler for the Hoover Reservoir count from its first count in 1956, with the exception of two years, until he said it was time for him to slow down and he asked me to take over the responsibilities. When I secured the detail for the past years from Tom I appreciated how much he had done with so little help. Tom laid the foundation and I have tried to maintain both good coverage of the circle and the sharing of experience with those just becoming involved. As a compiler for a Christmas Count circle I wish to express my appreciation to all the people who join in to help make a count successful. Without them I and the other dedicated compliers would not be able to conduct our Christmas Bird Counts.

Additional Notes

Our final count was 83 species.  Absent from the count for the thirteenth time in the last 17 years were Black-capped Chickadees. With the bitter cold weather I expected to find some this year, nada. Pine Siskins had been regularly seen in Central Ohio except for Count Week.
