Last weekend at the Sax-Zim Bog Birding Festival, there was a Pine Grosbeak that was said to be “xanthocromic”. That term means there are yellow feathers. This Grosbeak has that orangey-yellow feature. The next photo is a normally pigmented male Pine Grosbeak
I question this being a female as there are “Bronze” Pine Grosbeak and this may be a young male transitioning into his adult plumage. This time of year before the Pine Grosbeak return north to Canada, they are molting into their adult plumage. It is interesting watching the different shades as they change.
