It's still going on in my neighborhood on the Stanford campus at the edge of the foothills. Here's a passage from the Bent Life History account of the species referring to this phenomenon: "Mrs. Allen (MS.) has noted the following imitations by thrashers at Berkeley: long-tailed chat, red-tailed hawk, robin, ruby-crowned kinglet, olive-sided flycatcher, titmouse, house wren, willow goldfinch, California jay, quail, purple finch, European blackbird, frog, and postman's whistle. Most of these were recorded in September. In eight different years she found the song period marking the completion of the molt to begin in August; in 11 years the starting of territorial song ranged from December 21 to February 22". As to the accuracy of Bent's reports, however, compare text with picture: "When it feels the urge to sing it seeks the most conspicuous position available, the topmost twig of a large bush or small tree. The song ended, it spreads its wings and glides back to earth. At no time does it share the fondness of many other ground-foraging birds for the roofs of buildings." http://www.geocities.com/tgrey41/CaliforniaThrasher7.jpg Tom Grey http://www.geocities.com/tgrey41/index.html _______________________________________________ Do not post admin requests to the list.
