Barbara Pratt was surprised to see this little bird at her feeder. It's a nearly-white Dark-eyed Junco. We used to call this partially albino, but the correct term is leucistic.
You can see in the second photo of this unusual bird that there is a normal-colored Junco on the right. Barbara said this bird seemed to be accepted by the other Juncos. It surely is a striking sight!
Thanks to Barbara for allowing me to share her photo with you here.
