A limited foray into northern South Park in Park County in the early
afternoon produced rosy-finches in small numbers at Jefferson (
*Gray-crowned* and *Brown-capped*), and moderate numbers at Fairplay (
*Gray-crowned*, *Brown-capped*, and *Black*) and Elkhorn Road in the region
of Goshawk Road (*Gray-crowned* and *Brown-capped*). Silverheels Road had *Pine
Grosbeak*, *Gray Jay*, *Am. Three-toed Woodpecker*, and *Red Crossbill*
(Type 5), and a handful of rosy finches. Nothing of note at Como, and most
other areas I looked at were bird free.

COBirders,
I think the secret to seeing the mass of Lapland Longspurs is to be out during the snow storms.  A few of us have been out in Kit Carson for a couple of months and finding large flocks on days without bad weather does happen of course but they are at best just large flocks.  Yesterday I was out almost all day and checking the known good areas when I could and had almost zero birds even though it was stormy.  The difference though was that yesterday it was rain/ice almost all day which seem to ground all the field birds.
Now, fast forward to today.  Today it was 20+ MPH winds and snow most of the day.  The MASS of birds were back.
 
Glenn and I got to sit and watch this event for an extended period of time.  The area we watched today was 4 times larger than the one from last week.  I have posted another video from today that just shows the first layer of birds and near the 2:45 mark you can see a second layer and maybe the best part of the video.  The thing that we cannot capture is that this video only shows about a quarter mile deep worth of birds.  There are multiple layers of birds that span across a couple of miles.  So just imagine swarms of birds all over roughly a couple of square miles.  Our estimated numbers from today were as follows:
575,000 Horned Lark1,250,000 Lapland Longspurs
Here is a the video that shows a small fraction of the total birds.  Again, if you watch the video but are impatient, jump to roughly the 2:45 mark.  I took this video while driving almost two miles, it is just a bit shaky ;) but I don't think it should make anyone sick.
https://youtu.be/WURlpcWPnug
If you are interested in trying to see these birds I would recommend coming tomorrow if at all possible but do not expect these numbers as it is supposed to be nice but with the bit of snow on the ground there should still be decent numbers.  Otherwise, watch the weather for out here and when you see snow, not rain, in the forecast come out and see what you can see.
The location of the flock today was along Kit Carson county road G roughly between CR 9 and where CR 7 would be if it were there.  Also, if you come, look at this field carefully as it is this type of field that the birds tend to like best.  So you could then drive back west into Lincoln county and probably find the same thing.
Good birding!

Quite a few interesting birds around Pueblo lately. I finally was
able to bird for the first time this year in Colorado, last week (I
was out of the state until 4 January, and then stuck at home after
that, with the snowy/icy roads and weather). Here is a summary of
what birds I've seen.

Barrow's Goldeneye - one adult male, one immature male at Pueblo
Reservoir, 11 Jan

Ruddy Duck - one female Valco Ponds in Pueblo, 10 Jan
Common Loon - one to seven at Pueblo Reservoir, 10-14 Jan

Greetings All.
 
 
Sorry that I've contributed so little of late.
Yesterday, Sean Walters and I visited Aurora Reservoir for the last 4 hours of daylight.
It was a stunning, frustrating, rewarding experience all wrapped in one
And a bit chilly
 
 
The southern half of the reservoir is frozen, so most birds are reasonably close to the dam on the north side -- if you have a scope. Be sure to pay the entrance fee if you don't have a year pass, as enforcement has been vigorous (if also pleasant) this winter.
 
 
Anyway, Sean and I arrived to 300 or so Herring Gulls, far more RB Gulls, and a variety of other gulls salted in. There were 20K plus geese on the reservoir, 90% or more Cackling. We'd only done a modest job of scanning the gulls when Cheryl Teuton and Dan Brooks pointed out the Black Brant sitting nicely at the nw. corner of the reservoir. As we headed in its direction, a Bald Eagle came by, and pretty much every gull left the reservoir (excepting some Ring-billeds). Rather stunning actually. A lot of the geese fled, too. Over the next couple hours, most of the large gulls returned, and the geese returned with reinforcements.
 
 
During the last hour, birds poured in. A single flock of incoming gulls contained 3100 birds, all of which appeared to be Ringers. Goose flocks came by very 5 minutes or so, numbering 500 to 5000.
 
 
In the end, among the gulls, we were able to detect
2 first year Glaucous-winged Gulls
2 Glaucous-winged x Herring Gulls
14 Thayer's Gulls (this is really an estimate, and given how hard they are to pick out, the number was probably larger)
18 Lesser Black-backed Gulls (mostly adults)
The ongoing first-cycle Great Black-backed Gull (towering over the lesser gulls)
2 immature Glaucous Gulls
and one utterly baffling Thayer's/Iceland thing
 
 
For waterfowl, the duck of the day was the ongoing female White-winged Scoter.
Our final estimate of Cackling Geese was a staggering 115,000 -- but only 1000 or so Canadas.
 
 
The Black Brant was a delight. As far as I can tell, this is the same bird that has been seen over the last month or so in Adams County and at Aurora Reservoir -- all pics show a first-year bird similar in color.
 
 
In part because we were distracted by so much activity, we picked out only 3 hybrid geese, one each of Snow x Cackling, Ross's x Cackling, and G White-fronted x Cackling (compared with 9 hybrids in a flock of approx 37.5k geese in the Poudre Ponds on north side of Greeley on same day).
 
 
Turnover here is significant, and one should not assume that today's gulls are the same as yesterday's. At one point, the Glaucous Gulls being seen here were adults. Now, immature. The first Iceland Gulls were adults, the ones seen later youngsters. The ratio of LBB Gulls seemed distinctly more skewed towards adults today than last week.... and so on.
 
 
So, goose hybrid musings.
It seems to me that, in n. CO, white-cheeked geese - particularly Cacklings - become more common as one goes from Sedgwick County to Weld (and into Boulder/Larimer). On the other hand, Snow and Ross's Geese show the opposite pattern. Hybrids often look rather like the blue form of Snow Goose (see https://www.flickr.com/photos/36088296@N08/albums/72157640339259034), and I think that for every "real" Snow Goose that I see in Weld/Boulder/Larimer Counties I see 2-3 of these hybrids.
 
 
For some reason, the Snow/Ross's x Canada/Cackling hybrids seem to prefer to hang out with Cackling/Canadas rather than Snow/Ross's flocks. In Europe, Graylag x Canada hybrids behave similarly, usually hanging out with Canadas. Dunno why.
 
 
So
On that note
 
 
Good Luck and Good Birding
