Raynor, G S

As part of a program to characterize the plant and animal life of the Laboratory site and the surrounding region, the two breeding bird censuses originated in 1977 were continued to 1981. Coverage was better than in 1980 and comparable to that of earlier years. Fifteen trips were made to the BNL plot and thirteen to the Westhampton plot. Four observers censused the BNL and five the Westhampton plot. The number of species and of territorial males on the BNL plot increased to about 1977 to 1978 levels, reversing a several-year decline. Little change was evident at Westhampton except for a large increase in the Rufous-sided Towhee population which doubled the previous year's count and brought territorial males to the highest number yet recorded.
