I think this is a mutant dark eyed junco - ideas?!

7 posts in this topic

This bird was in our back yard yesterday, in Norton, MA USA.

It was with a mixed flock of sparrows, cardinals, and juncos. The shape is junco but coloration looks like a junco dipped in white paint.

Any thoughts? Are mutations common in juncos? I don't believe it to be some other species of bird but I've been wrong before!

Thanks.

Here are some pictures of the blizzard and digging out, plus the birds that visited after the storm, in case you are interested:

It's a partially leucistic dark-eyed junco - cool sighting! The bigger bird in the other pic is a fox sparrow - nice!

Welcome to Whatbird, pbgalvin!

Leucism is a pretty common mutation in birds. We get quite a few "mystery" birds posted here that just turn out to be leucistic.

Thanks TheBillyPilgrim,

Probably seen other leuciscts before but this is the first confirmed. Not sure if it's "life list" worthy but interesting at least.

Noticed you have a link to a costa rica trip. Going there in March so will definitely check out your report.
