baby goldfinches. They look similar to the females or goldfinches in winter colors and their baby call is a "♪ High, low...♪ high, low, low."
The immature American goldfinch has a dull brown back, and the underside is pale yellow. The shoulders and tail are dull black with two buff-colored wing bars, rather than an adult’s white. This coloration is the same in both male and female.
If you still aren’t sure if it is a baby or a female goldfinch, look at the feathers. Young American Goldfinches have fine, clean feathers and the adults will look worn out as they molt their feathers for winter.
