Dave Leatherman puzzled over Hammond's vs. Dusky -- something that all of us
puzzle about, I think.
I try to distinguish Hammond's vs. Dusky by their call notes. Dusky has a
fairly sharp 'pic' whereas Hammond's has a longer or less sharp note that, to
me, sounds rather like a Pygmy
It is always dangerous to make too much out of an odd bird report here and
there. But it seems to me something is definitely going on with Cassin's
Sparrows and maybe other southern species. Populations of birds, particularly
grassland species, expand and contract dramatically from year to
The Bobolinks south of Castlewood Canyon were putting on a show this morning,
singing atop fence posts along the road. I could not find any Dickcissels at
this location however. I also dipped on Yellow-billed Cuckoo in Louviers and
American Three-toed Woodpeckers at Hwy 67 and Rampart Range
Hello all,
Considering that others have been reporting Cassin's Sparrow at Chatfield, I
will mention that there was one singing there on 10 June. I was hiking on the
trail on the east side of the South Platte River south of Kingfisher Bridge,
and the bird was east of the river. Sorry that I
Cobirders,
Tom Halverstadt showed Harriet Stratton and I nesting Yellow-billed
Cuckoos in Louviers Wednesday evening, June 15. I've attached a link to my
Flickr site showing the female summoning the male, the pair copulating,
sharing
food, eating food and the female on the nest. Enjoy!
Hi Dave everyone,
There has also been an invasion of Cassin's Sparrows into central Kansas in
areas where they are seldom if ever recorded. Right now there are numerous
singing males at Cheyenne Bottoms, Quivira NWR and, oddly enough, in the
Wichita metro area. So while Front Range
Glenn Walbek and Charles Mills have responded to my post earlier today with
interesting information.
Charles let me know they now have reported multiple Cassin's Sparrows in
extreme sw AR, with at least one pair among these suspected of breeding. He
also reports this species is being seen in
Today around 7:30AM I arived at Big Johnson Res.and re-found the tern
within minutes,
but I waited 15-20 minutes until the bird flew around, so I could see the
field marks in the wings.
Nice find Mark!

We went to the Devil's Kitchen trailhead this morning at about 7:15 AM. Both
Black-chinned sparrows were singing close to where Chip Clouse had reported the
farthest one a few days ago, at about 400m up the No Thoroughfare trail, past
it's confluence with the Devil's Kitchen trailhead. Many

Interesting to read the comments on Cassin's Sparrows . What a
difference a little rain makes. I did an atlas block in Eastern El Paso this
morning and must have had a minimum of 50 Cassin's singing , carrying food etc
etc . Just two weeks ago there were virtually none
Greetings All,
RE: Cassin's Sparrows, there are a number of phenomenon likely involved in
various data presented.
To parse some out, the LONG DISTANCE vagrancy of Cassin's Sparrows may or may
not have much to do with summer irruptions n and w of their normal breeding
ranges.
Some of the

Late this afternoon, Jeff and I wandered up to Greeley to see if we
could find the Yellow-crowned Night Heron in Glenmere Park. There we
ran into Shawn from Loveland (sorry, if I’ve misspelled your name) and
his family who were there on the same mission. Eventually we all got

We'll try again - this time with a subject!

I was gone from 7 am to 7pm today so didn't get a chance to check on birds
for tomorrow morning's field trip I am leading until this evening. I
refound at least 2 Black-throated Sparrows at 7:15 pm by hearing their
tinkling calls. Then one of them began singing and did so intermittently
until
Hello, Birders.
Andrew and I explored Park County earlier today, Saturday, June 18th.
We started out in the Buffalo Peaks campground of Pike National Forest, where
we got our wake-up call from booming and buzzing Common Nighthawks. The two
dominant voices in the dawn chorus were Olive-sided

I was able to get back to Big Johnson today and I was unable to find an Arctic
Tern. I also looked for the Bald Eagle nest that I believe is somewhere
along Fountain Creek but had no success with that either. There was a single

I suspect the sparrow tweet each other about the condition of the habit :)
