This is a somewhat recent arrival of a new species at my backyard feeders. A male Ruby Crowned Kinglet. During the first few visits, I realized that this wasn't a Warbler, Vireo or junior Lesser Goldfinch. When he flashed his normally hidden red crest, I knew all those guesses were incorrect. Took a bit to get a positive ID but it's now confirmed. This is from All About Birds - "Ruby-crowned Kinglets are olive-green birds with a prominent white eye ring and white wing bar. This wingbar contrasts with an adjacent blackish bar in the wing. The “ruby crown” of the male is only occasionally visible. These are restless, acrobatic birds that move quickly through foliage, typically at lower and middle levels. They flick their wings almost constantly as they go." Means they're frantic, super active and challenging to photograph.
