The last Colorado Field Ornithologists (CFO) Records Committee report in Western Birds was for 1976–1977 (Andrews 1979). The time elapsed since the last report precludes discussion of all records handled by the Records Committee (RC) in this period, so this report covers only first, second, and third state records, and new or very unusual definite breeding records for Colorado from 1978 through 1985.
The full reports of the RC for this period can be found in Chase (1981, 1982, 1983) and Gent (1984; 1985a, b; 1986). This report discusses 21 additions to, and 8 deletions from, the CFO state list, resulting in a net gain of 13 species from the 427 mentioned by Andrews (1979). Thus, the CFO state list for Colorado currently stands at 440 species, 5 of which are introduced. Andrews (1980) summarized the state list in 1980, and the present list is summarized by Gent (1987).
