Diseased Bird: White-Crowned Sparrow with partially feathered belly
Additional images:
This bird has what appear to be feather shafts growing on his belly. This may be the same bird reported earlier, “White-crowned Sparrow with featherless belly” who is now growing new feathers. Thus, the bird may not be a “sick bird” but just molting here on his wintering grounds.
