[cobirds] Lapland Longspurs - DIA Loop - Adams County

If you don't have Lapland Longspurs for the year, today was the time to get them along the DIA Owl Loop.  I would list all of the spots, but there were too many.  Everywhere along the route starting 1/2 mile east of Tower Rd on 96th Ave to 120th Ave just west of Haynesmount.  Almost every single flock of Horned Larks contained some longspurs in it, whether the flock was 100 or more birds or just two dozen.  I backtracked from there, so I'm sure there are more flocks of birds on the other roads out there and all around.  

For those that have no interest in tiny birds, there were also the usual assortment of wintering raptors; American Kestrel, Red-tailed Hawk, Northern Harrier, Rough-legged Hawk, Ferruginous Hawk, and Bald Eagle.  

At one point, I just stopped to watch the action in two Cottonwood trees that were close together.  In one, there was two adult Bald Eagles.  The other tree trunk and branches looked a bit like a lava lamp.  The Red-winged Blackbirds were swarming and moving up and down and around it.  It was rather mesmerizing.

[cobirds] Re: Evening Grosbeaks Weld County

We haven't had ANY Evening Grosbeaks this winter at our feeders. Since we moved here 3 years ago, they occasionally dropped by to my delight. I wonder if the floods have anything to do with this? There has been a lot of unusual wildlife experiences here in Coal Creek Canyon this winter.

[cobirds] Colorado Birds, vol. 48, no. 1

Hello, Birders.

Earlier this week I received in the mail vol. 48, no. 1 (Winter 2014) of COLORADO BIRDS, the quarterly journal of Colorado Field Ornithologists. It's wonderful! Let's take a look:

* Front cover. A frame-filler Hoary Redpoll by Bill Schmoker. Beautiful! The photo, that is... ;-)

* Back cover. Immature Broad-winged and Red-shouldered hawks by Glenn Walbek and Tony Leukering. Which brings us to...

* In the Scope, pp. 78-80. An article by Tony Leukering on separating juvenile Broad-winged and Red-shouldered hawks, definitely an ID conundrum for us in Colorado. Tony is a nationally renowned expert on bird ID and distribution, and it's awesome that he contributes regularly to Colorado Birds.

* Caterpillar Tricks, Part 2, pp. 72-77. In the first eight words of this article by the incomparable Dave Leatherman, we encounter the words "eggplant, "India," "Pale," and "Ale." The last six words of the article are "Like frass and copulation, trickery happens." If you miss this article, your life is woefully incomplete.

* Birding on the Dark Side, pp. 65-71, by Yours Truly. The summer doldrums in the dead of night...It's an excellent time to go birding! I heard owls, sandpipers, sparrows, thrushes, and more. The astronomy and human companions were splendid too.

* "A Century of Waterbird Population Trends in Boulder County, Colorado," pp. 11-41. In this major research paper, Jameson F. Chace and coauthors document human impacts on ducks, cormorants, grebes, coots, and even Willow Flycatchers.

And much more: a book review by Bob Righter; Mike Henwood's thorough summary of June-July 2013 bird records for Colorado; an essay, also by Mike Henwood, on the famous Brambling of November 2012; trip announcements and trip reports; CFO business and a message from CFO President Bill Kaempfer; and even photos and bios of all the authors.

I'm grateful to Editor Peter Burke for this educational and fun issue of Colorado Birds.

All members of CFO receive Colorado Birds. Join CFO here:

[cobirds] 100s (not 1000s) of Rosy Finches, Larimer County

Yesterday, mid-morning, while we were skiing in Lory State Park near Fort Collins, we were surrounded by hundreds of rosy finches.  We were in a burned area in the valley and they were working the grasses and the burned mountain mahogany.  We stood stock still to hear and feel all these birds around us. It was comical as several would land on the top of a stalk of grass and then swing down to the ground as though they were playing.  It was magical and they didn't seem bothered by us at all.  We were the only 2 people around.  As we skied further up the valley, several more groups of rosy finches would appear.  I don't think it was all the same group as the same thing happened when we skied back down the valley.  There were also flocks of juncos and some tree sparrows mixed in with the rosy finches. Each flock of finches was maybe 2-300 each. We also saw one solitaire, several magpies, and a kestrel.

[cobirds] Waneka/Greenlee, Boulder County, 2/1

Hello, Birders.

The big snow we were supposed to get Thursday night was something of a dud; but the light dusting we were supposed to get last night turned out to be a doozy. So I went out this snowy Saturday morning, February 1, to see and hear the birds at Waneka Lake and Greenlee Preserve, eastern Boulder County.

For a glorious instant at 6:43 a.m., it was almost perfectly silent: no traffic on Baseline Road, no sounds from the neighborhood, no dogs barking, no wind...just the quiet hiss of falling snow. Then a female Great Horned Owl hooted, followed immediately by a male. There was something achingly pure about the moment. It's hard, in this day and age (or at least at my age!) to give anything your undivided attention. But that's how it was for a brief moment this morning. 

The owls quieted down after just a few series, and it was silent again. I might as well have been floating calmly in the depths of outer space. Then a few Horned Larks flew over, tinkling like little bells.

Next there was a great clamor over at Waneka Lake. Maybe a Bald Eagle was coming off a roost? Anyhow, the geese all put up, then put down again. And the gulls were starting to come in. Waneka has had many, many gulls and geese of late. I haven't been paying much attention (that danged, divided-attention thing), but I can tell you that the gulls are onsite by about 8am, and the geese remain until around 10am. So the best time is 8-10am. As I said, I haven't been spending too much time out there, but it's been hard to overlook the handsome adult graellsii Lesser Black-backed Gull visiting the place. (By plumage, it's not the same individual, I believe, as the bird that's been seen over at Boulder Rez.) And I think I saw a white-wing (Glock?) there the other day, but I didn't have bins.

It's a lovely morning. I don't care if you go birding today, but I demand that you go outside and behold the beauty of a snowy morning in Colorado.
