Annual Winter Bird Count, 1990-1999,
Archbold Biological Station, Lake Placid, Florida

Project Director: John W. Fitzpatrick, Cornell University
Database Manager: Fred E. Lohrer

During 1990-1999, 10 annual Winter Bird Counts (WBC) were conducted in mid-January, on 4800 acres of Archbold’s main property (but excluding the southeastern-most Hicoria Tract), using National Audubon Society Christmas Bird Count (CBC) methods. The effort was to count all birds at the Station. The WBCs gave us a good assessment of Archbold’s winter bird community and a better understanding of species population trends and relative abundance. The Archbold data can be compared with the adjacent and overlapping Lake Placid CBC, conducted during the same years in late December, and with many other Florida CBCs. Tables 1,2,& 3, below, were compiled by Fred Lohrer in February 1999. See Archbold's Biennial Report 1999-2000 for some preliminary analysis of the count data.

Metadata

Study Area. During 1990-1999, 10 annual Winter Bird Counts (WBC) were conducted on 4800 acres of Archbold’s main property (but excluding the southeastern-most Hicoria Tract). The count area was divided into 15 units following property tract boundaries (see map [b]).
Dates. Counts were conducted in mid-January. For all years counts were conducted on days with normal seasonal temperatures and, but for one year (1994), on days with little wind (see Table 1 below).
Methods. Counts were conducted using National Audubon Society Christmas Bird Count (CBC) methods. The effort was to count all birds at the Station.
Observers. Biases from observer variability were minimized by using, as much as possible, the same observers year after year in the same property unit, and usually units the observers were familiar with from their field research. Two observers participated in all 10 counts, one in 9 counts, and several in 6 counts. Overall 55 ornithologists and field ecologists participated (see Table 1 below).
