Hi Tweets -
This past Sunday morn had a surprise on the ground below my seed feeder (now empty). It caught me off guard because I'd never noted such a thing as a Tan-striped White-throated Sparrow. I considered it was an odd hybrid or something. The well-delineated white throat made it nothing else but checking some books I discovered it to be a "normal" morph of the White-throated. A first for me!

I'd be interested to hear if others have observed this morph and to get some idea of its relative occurrence. Thanks in advance.
