I think the facial pattern is to weak for Purple, although there´s a slight hint of it but not somewhat like this:
JanJ - Purple finches are variable in the amount of facial pattern. In the pacific populations, this bird would be typical.
>>>Purple has a straight culmen with a slight down-curve to the tip at best, while House have the familiar distinct curve throughout the whole culmen. However, in KC's bird culmen is more or less straight, <<<<
Yes, the relatively straight culmen was another plus for Purple, but I figured since it seems to have a degree of deformity it may not be diagnostic enough to mention.
>>> in KC's image the undertail coverts are slightly streaked, which can be seen in all Carpodacus finches.<<<
There is slight streaking in all, but house finches are more heavily streaked through the UTCs, so faint streaking is again more indicative of a Purple than a House.
I appreciate the response & the links, JANJ. However, I have to say KC's bird still looks like a PUFI female to me.
Cheers!
