A while back when I was getting serious about birding, I posted to this list that I'd found a flock of Purple Finches in Lyons; a few of you then introduced me to Cassin's Finches. :-) :-)

I promptly sent out a correction. 

But now I have redemption, and today found what certainly seems to be an actual Purple Finch! And the behavior is just like some of you told me it would be - a single bird at someone's feeder. 

Location and photos can be found on the eBird list: https://ebird.org/checklist/S75437331

Happy birding,
- Chris Petrizzo, Broomfield

Chris,

Separating Cassin’s Finch females from Purple Finch female can be very tricky. I think the streaked throat and rump, pale eye ring and crisply streaked breast support an ID of Cassin’s Finch. Did you hear it call?  Call notes differ.

Lack of dark streaks on undertail coverts favors PUFI, i recall.

Hi All,

I think the streakyness is subjective, as I think Chris's photos show a more blurry set of streaks than I would expect on Cassin's Finch. I think the bill shape, being stubby and very thick, is different than I would expect on a Cassin's finch. The facial pattern seems to be stronger than your average Cassin's, and the ustreaked undertail coverts in this bird ties the ID together fairly nicely as a Purple Finch, in my opinion.

Thanks,

After review of many photos of both species using the Explore feature of eBird, I am on board with Purple Finch. The curved
culmen of the upper mandible, the deep chocolate brown of the plumage on the head and back with some white streaking on the back, as well as unmarked under tail coverts are all features of Purple Finch. Nice find!
