Golden-crowned Kinglet in Fall Migration Plumage.

Golden-crowned Kinglet in Fall Migration Plumage.

Tiny, hyperactive songbird usually found in conifer trees. Look for black stripes on the head and bold wing pattern. The namesake golden crown is usually just a small stripe, but can be flared into an expressive fiery-orange crest when agitated. One of the smallest passerines.

White-crowned Sparrow Juvenile 

Medium-sized sparrow with brown-streaked upperparts, small white throat patch, and plain gray underparts. White crown has distinct black lines. Wings are brown with two pale bars.  Sexes are similar. Juvenile has buff and brown head stripes. Diet consists primarily of seeds and insects. Short flights, alternates rapid wing beats with brief periods of the wings pulled to sides.

I didn’t know what type of sparrow this was and looked it up using Merlin Photo ID app.  Juveniles are always difficult to recognize.
