[cobirds] Ruddy Turnstone Jumbo Res Sedgwick Cty
Cobirders, Erthal reports a Bloody Turnstone on the Sedgwick County side of Jumbo reservoir. The bird was found at the end of a point that extends out into the reservoir. Search along the rocky shoreline for this bird. Good Birding, Steve Stachowiak Highlands Ranch, CO -- You received this message because you are subscribed to the Google Groups Colorado Birds group.

[cobirds] Reddish Egret, Bent County, 8/27
Birders, The white morph Reddish Egret first found on the west end of John Martin Reservoir on August 18th is still present as of August 27th. Easiest viewing access is from the north, but the bird is usually about 1 1/2 miles distant from the vantage point on cliffs above the mudflats. Closer views are possible from the south, but the drive is much more complicated. Today, there were three Snowy Egrets and one Great Egret with the Reddish Egret, so seeing a white heron is not exactly conclusive ID. The Reddish Egret is notably long-legged, stocky bodied, and long necked, and feeds in typical Reddish Egret fashion. It is significantly larger than the Snowy Egrets, and a bit smaller than the Great Egret. Land birds were pretty good this morning in Bent County. Green Heron Slough had a weakly-singing Black-and-White Warbler and a Northern Waterthrush. Hasty Campground hosted yet another Black-and-White Warbler.

[cobirds] Connecticut Warbler-maybe? Crow Valley Campground
Hey all! Headed to Crow Valley this morning to try and re-find the Connecticut Warbler. There were several possible sightings but no definite ID. This bird is tough to see and doesn't like to leave the brush. I had to leave around 11:30am and Mark Chavez and Kirk Huffstater (hope I spelled those names right) were still searching. I'm sure they'll post if they got a good look at the bird. Other sightings included 1-Black and White Warbler -southwest corner 1- Cassin's Vireo- just south of the picnic area 8-10 Townsend's Warblers all over the campground 2 Macgillivray's Warblers Many Wilson's and Yellow Warblers 1- Yellow-breasted Chat 2- Warbling Vireos and the usual suspects Good Birding!

Re: [cobirds] Loon molt
Nick et al.: While wing molt may not be the cause of the McIntosh PALO not diving, there are any number of other possibilities, such as illness. However, it might behoove us to know what it's eating, if anything. If nothing, that could provide more suggestion in the vein of illness or other infirmity. However, loons eat things other than fish, though usually considered obligate piscivores. From the Common Loon BNA account (I couldn't get to the PALO account) -- bna.birds.cornell.edu/bna/: Crustaceans—e.g., crayfish (Decapoda) constitute major part of diet when fish are scarce or water is murky (1.0 m visibility), up to about a third of diet for males and more for females (Barr 1973). On some Wisconsin lakes, observed adults and chicks regularly observed foraging on snails (W. Piper, pers. com.). Leeches (Hirudinea) are occasionally an important food, and individuals that are stressed or ill sometimes eat vegetation (Barr 1973). Having no chance to go see the loon in question, others will have to provide the data on the bird's foraging, or lack thereof.

[cobirds] Chihuahuan Raven Colorado Springs, El Paso County
I had a Chihuahuan Raven calling in a tree across the street from my house for about 30 minutes this afternoon before it flew away. It was pulling some bark off the tree and from my scope view, it had some wing feather sheaths showing.

Re: [cobirds] Loon molt
Hi Folks, I just returned from watching the Big Mac Pac Loon and it was diving frequently. Many of the dives were very short, 1 - 4 seconds. A few were closer to 10 seconds and one time when I got to 20 seconds I looked around and realized it had swum out of view while under. It was also spending a lot of time simply holding its head under. The clartity of the water was rather poor. You cannot see the bottom three feet from shore. There was just a slight breeeze and it was only making a ripple on the surface. I wonder if its behavior could be due to the water conditions rather than illness of injury? I also found a City of Longmont doc which states that fishermen could expect to catch carp, walleye, and crappie. And the shoreline has always been popular with large waders like Great Egret and Great-blue Heron.

Re: [cobirds] Loon molt
When Joel and I observed the loon on July 26th, it dove frequently and readily enough (every couple of minutes). It would stay under for 30 seconds at most and seemed to have its head underwater for most of the time otherwise. It had a fairly good success rate, as it came up with what I believe were shad (a non-game fish which I know to be in the lake) every dozen or so dives.

[cobirds] Mississippi Kites , Colorado Springs

[cobirds] Crow Valley and Lower Latham
hi Cobirders Went up to Crow Valley first Friday morning. Almost 11AM and very little activity too warm. I did see Mark Chavez and Huffsetter (?) soon joined by Dick Schottler all had watched for the Connecticut Warbler. They did not see it neither did I. I also met David Simpson and wife Dee from Florida. We birded together for a short while. Saw a small Flycatcher, his wife photographed and we were unable to identify. We came across a few warblers including two male Townsend Warblers. I ate lunch and headed for Lower Latham and the flooded meadow on the south side of Rd 48. There were hundreds of Shore birds here. Great variety. There were 4 Black-necked Stilts and 6 American Avocets. Lots Killdeer and sandpipers I made tentative ids. There was one larger sandpiper with very red legs possible female Spotted Redshank ( really impossible!) Sibley shows one in Kansas. Also there were two female Ruffs nearby with characteristic hump in middle of back with feathers loose. I hope all this stuff is still there early Saturday and someone can get pictures. I didn't take camera today of course! Bob Spencer resides N.W. of Golden -- You received this message because you are subscribed to the Google Groups Colorado Birds group.
