This juvenile Sharpshin has buffy tips to most of its wing feathers. A common feature in juvenile songbirds, l am now beginning to appreciate how widespread it is among unrelated birds. Robins and Swainson's Thrushes show the feature, but molt into plainer feathers in a matter of days to weeks. Nonpasserines apparently retain these feathers to some degree for much longer. I recall photos of Snowy Plover with such buffy scallops on the back. To my eye it makes the Sharpie look ornate relative to its adult kin. But l suspect if it serves any real function, it alerts adults to its age status and by default feckless nature and will hopefully inspire them to cut it some slack.
