Feeding in our yard today was a White-throated Sparrow with a tuft of seriously misplaced feathers. They protrude from the bird's rigth flank, like a feather duster attached to the bird's hip. Behavior of the sparrow appeared ordinary. It moved on the ground and flew without apparent problem. Did the bird have a narrow escape from a predator, a claw tearing the feathers as the bird flew? Looks like a lot of feather for that part of the body doesn't it? And the dark color seems wrong. Doesn't make much sense. The sparrow's bill appears odd because the bird was manipulating a piece of cracked corn.
