Identification - This plump bird is sparrow-sized with a striped black-and-white head. Some may have black tan stripes. There is a tiny patch of yellow between the eye and bill. The back is streaked with brown, the throat is white, and the underparts are gray. There are two thin wing bars on the brown wings. The bill is dark.
Morsels - It is an odd fact that the two different forms of the White-throated Sparrow have different temperaments. The black-and-white striped form is more aggressive than black-and-tan striped form. This riddle has yet to be solved by ornithologists. But they do know that most pairs are comprised of one of each form.
