This sharply defined Sparrow can be found in Arizona year-round, throughout most of North America in the Summer. I think of chipping Sparrows as bring the quintessential Sparrow because they seem to combine many elements of the different Sparrows into a sort of general template.
The rufous cap is found on many different Sparrows, and you'll often find the white supercilium on others, and a dark eye-stripe on still more. But only the Chipping Sparrow brings it all together, making it a straightforward and handsome bird to identify.
