Hi Jim

I looked up the purple finch in Cornell "Birds of North America" (subscriber). There seems to be an immature PF with a similar look, but there is also a yellow variant that could fit your photos. I also wonder if these are leucistic birds...

A search for the variant /photos brings up quite a variety. Not all are reliable, however.

I don't know if you can see these from the Macaulay Library. Quite a lot of variation there too.

I'm sure the experts will chime in...

A few weeks ago a strange looking purple finch appeared in my yard. It had a yellow patch under its bill that I had not seen before. It was back today with 4 other purple finches. And one of them was ever stranger looking.  The patch was larger and the bird had a very yellow-orange tint. If anyone has any ideas if these are anomalies or within a normal variation in markings, I would like to hear your opinions.

 

I put photos here:
