The Savannah Sparrow, like the White-throated Sparrow, has yellow on its head. The yellow band on the Savannah goes above and behind the eye, whereas the White-throated Sparrow’s yellow ends at the eye. Also notice the spotted breast on the Savannah (the White-throated’s breast is clean).
I love the color composition on this one. And, of course, that the Sparrow is singing.
Clearly this rascal is not cognizant of this nation’s ongoing obesity problem!
