Scott, et. al: Here are photos of a Golden-crowned Sparrow x White-throated Sparrow hybrid at Mt. Tabor Park in May 2011, found by me, Adrian, and Dave Irons. I believe Dave spotted it first. http://www.flickr.com/photos/90462915@N07/8578563851/in/photostream/ I would expect a hybrid to show more intermediate characteristics than Scott's bird, like the bird from Mt. Tabor, but it is always difficult to be sure. Cheers, Christopher Hinkle
