Bird Counts

The results of recent Gainesville Christmas Bird Counts (CBC) and North American Migration Counts (NAMC) are given here in tabular form to indicate which are the regularly-occurring and most abundant species in winter (CBC), fall migration (NAMC Fall), and spring migration / nesting season (NAMC Spring).


Christmas Bird Count 1995-1999

Although individuals conducted Gainesville CBCs in 1925, 1928, and 1949, annual counts with proper teams did not begin until 1957. Here we show the results of five recent counts.

Heavy rains inundated Paynes Prairie, which is at the Count center, during the winters of 1997-98 and 1998-99. The waters subsided rapidly during 1999, creating a bonanza for fish-eating birds. All these circumstances are reflected in the CBC numbers for 1997-99, such as the record high count of Anhingas in 1998 when the Prairie was to all intents and purposes a lake, and the record highs for several waders in 1999, when it was reduced to a series of shallow pools. Conditions for the 1995-96 counts were “normal,” however, and give a more typical picture of winter bird populations.


North American Migration Count, Spring 1992-1999

The NAMC was designed to be a one-day, continent-wide survey, a “snapshot of the migration” to use the words of its founder Jim Stasz of North Beach, Maryland. Since it was continent-wide, the date was fixed on the second Saturday in May, when migration would be coming to an end in the Deep South and just beginning in the Far North. Here we show the results of eight counts. They give a fair picture of normal spring migration (1994, 1997), but there are a couple atypical ones as well (1992 was a fallout year, and thus much better than normal).

Since all of our locally-breeding birds are actively nesting by mid-May, this count doubles as a good survey of summer bird populations.


North American Migration Count, Fall 1995-99

The NAMC instituted a fall count once the spring count was solidly established. It takes place every third Saturday in September, and thus gives a much better picture of fall migration than the spring count gives of spring migration. Five years are shown here.
