  • California thrasher spring songs and mimicry on Wolf Mountain, Nevada County, CA

    these files demonstrate the extreme variability, variations on a theme, and mimicry of the California thrasher.  The first files was recorded in the afternoon of March 8, 2008 in the chaparral on the top of Wolf Mountain, southwest of Grass Valley, California.  It is 7:30 minutes long and the bird averages 3 phrases per minute.

    At 1:36 the bird mimics an oak titmouse, at 3:55 a scrub jay and at 4:09 an oak titmouse again, this time very clearly.

    In this recording in the same area, another bird mimics a blue-gray gnatcatcher between 0:21-0:23, and a scrub jay at 1:10-1:12 a scrub jay.

    This is another phrase from the first bird.  In this I think I hear phrases from lesser goldfinch, scrub jay, and blue-gray gnatcatcher, but my ears are worn out right now and I could be dreaming.
