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. 17.6106833 bytesapplication/pdfen-USQL1 .A436 no.2176, 1964Vermivora pinus -- Behavior.Vermivora pinus -- Variation.Birdsongs -- New York (State) -- Huntington Region.Birdsongs -- Recording and reproducing -- New York (State) -- Huntington Region.Birds -- Behavior -- New York (State) -- Huntington Region.Birds -- Variation -- New York (State) -- Huntington Region.text
