This adult female (top) is an example of an uncommon extremely pale morph which lacks yellow underparts. Instead it shows minimal yellow confined mostly to the chin and malar region. Females lack the black crown of male (bottom) and generally appear drabber overall, with little white in the wing and no white in the tail. Unlike the similar American Goldfinch, Lesser Goldfinch lacks distinctive breeding and non-breeding plumages. Instead it keeps the same plumage year-round. Nikon CoolPix P510.
