摘要
We compared 13 song features among three populations of Yellow-eyed Junco (Junco phaeonotus): J. p. bairdi from Baja California Sur, Mexico; J. p. palliatus from southeast Arizona, USA; and J. p. phaeonotus from Oaxaca, Mexico. Songs of J. p. bairdi differed significantly from those of J. p. palliatus in 11 of 13 features and differed significantly from those of J. p. phaeonotus in six of 13 features. Songs of J. p. palliatus differed significantly from those of J. p. phaeonotus in only four of 13 features. Discriminant function analysis clearly distinguished songs of J. p. bairdi from those of the two other subspecies, which were not clearly distinguishable from one another. Additional investigations using playback experiments and genetic analyses may be warranted to better evaluate the merits of promoting J. p. bairdi to species status. Received 22 August 2010.
