A juvenile white-throated sparrow demonstrates the purpose of his drab coloration. While I am not 100% certain here, I judge this to be a juvenile. Not from this angle, but from the fuzzy angle to the right that shows some light streaking at the top of the breast that does not resolve into the stronger streaking and brown dot in the breast of the song sparrow. We have song sparrows commonly all year long. The white-throated sparrow is a winter resident only. Anyway, I like this photograph more for his camouflage coloration than his specific species.
