  • Most of us have heard the “Chicago” call of the california quail perched on the top of a fencepost or bush.  You may have wandered through oak scrubland that has thick cover either as bushes or blackberry thickets and heard mysterious liquid, clicking “putting” noises and been mystified.  These are also vocalizations of the California quail.  I was able to record an extensive quail session in one of these thickets at the upper part of Bridgeport SP in Nevada County, CA on the morning of April 17, 2007.

    In the background one can hear in the order of appearance: mourning dove, wrentit, western kingbird, Bullock’s oriole, golden-crowned sparrow, and lesser goldfinch

  • Acorn woodpeckers are common and sociable oak woodland birds in the Sierra foothills.  They are easily recognized by their clown-like faces and raucus calls.  In your wanderings you may have seen dead trees covered with holes that contain acorns.  These are called larder trees, and are the acorn woodpecker’s granary.  A breeding group of numerous individuals will cooperate in it’s creation and defense.

    This bird was recorded at the upper part of Bridgeport State Park along the Yuba River in Nevada County on April 17, 2007.  What you hear is the typical short, gutteral call.  Also present is the call of a  Bewick’s wren (Thryomanes bewickii).

  • This owl woke me on the evening of January 8, 2009.  It was calling loudly, and I had never heard a 6 note call from a great-horned owl before, only 4 note and 5 note.  I hurried, threw on a coat, and went on the deck with my recording gear and was able to get a series of calls before the owl quit or moved on.  The recording was made at my home on Banner Mountain, near Nevada City, CA.
