[A single song-type is represented here, but I suspect that this is Dendroica occidentalis NOT D. townsendi. If it was D. townsendi, it was a spring migrant because this species does not breed even remotely near the Sierra Nevada. This recording neither sounds like other recordings available for D. townsendi nor do spectrograms of these songs look like any of the figures of this species' songs in D. J. Borror and W. W. H. Gunn (1985. Songs of the Warblers of North America. Cornell Lab. of Ornithology). Although also not identical, the spectrograms do appear like those of D. occidentalis, a common breeding species in this region. Quality unchanged (2) - CAM - 20 January 2005]
