LBJs are not a mystery, unless you convince yourself that they are impossible to ID.
For example, in January, 09, we were in southern Arizona. I saw an especially plain little sparrow with no distinguishing marks; it was not difficult to ID Brewer's Sparrow
|Brewer's Sparrow - near Tuscon, AZ|
Brewster's Sparrow in desert brushy areas in winter defines drab bird.
Sparrows do not often provide clear, unmistakable field marks. The Black-throated Sparrow is a delightful exception. This one was photographed at a bird feeder in Patagonia State Park, Arizona, in January, 09. (Young birds are a bit more LBJ than adults.)
