Re: [cobirds] Boulder Purple Finches

Looks like a classic Cassin's where the forehead is the most vivid red/pink on the whole birds--combined with the very lightly streaked strawberry-colored breast looks perfect.  The straight culmen (top edge of the upper bill) compared to the curved culmen of a House Finch is also a plus.

I'm sort of hijacking your thread (sorry about that!!), but since you're talking about finches: I had this guy in my yard today, hanging with a flock of house finches. I'm not good enough at this yet to say what he is. I think not a house finch, but I'm not sure between purple and Cassins? Any help would be appreciated. 

Thanks!

While I was working on such details, two males suddenly appeared for about half a minute, and didn't return. 
Not a bad day--a Prairie Falcon zoomed by in the morning for a bonus.

Re: [cobirds] Purple Finch - Broomfield

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,

Will Anderson

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.

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.

Happy birding,

Re: [cobirds] Purple Finch - Broomfield

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

[cobirds] Dave Leatherman at Boulder Audubon program tomorrow night, Oct 27

Please join us on Tuesday Oct 27 at 7:15 for Boulder County Audubon’s next program.

 

The Webs of Life: Arachnids – ONLINE MEETING

Spiders, like snakes, are an animal group of which humans seem instinctively afraid. That is unfortunate because they truly are both remarkable and important. Join Boulder County Audubon on October 27th as we learn about spiders and their webs as key parts of bigger food webs, ID features, life history habits of the major groups and spider sex. We will discuss spiders doing photo shoots with bicyclists, winning contests, and as urban legends. We are sorry that we cannot offer personal “spider therapy” by inviting audience members to come forward to hold a tarantula – Zoom has not progressed that far. Yet.

Dave Leatherman was born and raised within the shadow of Ohio State University’s football stadium, where he began birding and bugging as a child. His education includes a BS in biology from Marietta College and an MF degree in forestry from Duke University. He is a retired entomologist previously employed by the Colorado State Forest Service for 32 years. Dave is a superb all-round naturalist. Many of you will be familiar with “The Hungry Bird” column which he writes for the journal Colorado Birds and his reports to COBirds from Grandview Cemetery, documenting the breeding and migrating birds that use this treed graveyard and what they consume. He also studies Loggerhead Shrikes and their impaled prey, dragonflies and about every other insect, adeptly photographing and sharing his research.
