Abstract
"A spectrographic analysis of tape recordings of Blue-winged Warblers at one locality on Long Island, New York, revealed the limits of individual and intrapopulational variation in the song of that species in an area where the closely related Golden-winged Warbler does not breed. Intrapopulational variation consisted of different combinations and sequences of four basic components. Individual variation involved minor alterations in the duration and configuration of these components but did not include changes in their combination or sequence. Each male had a repertoire of only two distinct song patterns. The significance of these findings is discussed with reference to reports that some Blue-winged Warblers have a greater variability in song in areas where the Golden-winged Warbler also occurs"--P. 17.
