Arapahoe County: --On Nov 6 the Kennedys were surprised and delighted to find a 
"way out of place" American Dipper where a bike path goes along a small 
tributary of Cherry Creek, Piney Creek, near the Orchard Road and Parker Road 
intersection. There are very few records of this bird that far east of the 
foothills. The oriental record setter was one at Julesberg in 1983, according 
to Bob and Bob. It was found again by Stecher on the 7th, at dusk, under the 
Parker Road bridge. 
--A Lesser Black-backed Gull was reported by Stecher at Cherry Creek far out 
from the marina towards the dam on November 8.
 
Bent: --On Nov 8 Leatherman reported a Harris's Sparrow and Winter Wren, the 
latter under the bridge near a huge heaped up pile of tree debris.  He 
describes the site as: "Arkansas River west of Lamar just north of place name 
of Prowers (Bent)." The birds were seen during his Nov 6-8 trip.   Prowers is 
about 97 miles west of Lamar on Olive Street which turns into CR HH.  The 
bridge over the Arkansas River is about 1 mile north of CR HH on CR 34.5.
 
Boulder County: --Birchmeier announced that there were 2 Pacific Loons on 
Lagerman Reservoir on Nov 5. --Schmoker espied a Pacific Loon on Boulder 
Reservoir on Nov 5.   --On Nov 6 there was a Winter Wren near the spillway of 
the main pond at Golden Ponds near Longmont, reported by Severs. --Kaempfer and 
Vanderpool noted an adult and an immature Tundra Swan at Lagerman on Nov 7 and 
Severs saw them fly over his vehicle heading toward Boulder Reservoir later 
that morning. Zilly saw one Tundra Swan on the north shore of McIntosh 
Reservoir near Longmont at noon on Nov 7. --Gent spotted 2 female/immature 
Black Scoters on Baseline Reservoir on 11/7. 
--2 Lesser Black-backed Gulls (1st winter, ad) were reported by Nunes at 
Baseline Reservoir on November 9.
 
Custer County: --On Nov 6 Rich Miller found a Snow Bunting north of Wetmore 
along the Custer-Fremont County line. The intersection there is County Roads 
298 and  297. He also found a Palm Warbler along Hardscrabble Creek across from 
the Wetmore Community Center. A search party on Nov 7 failed to find either of 
these goodies. 
 
Douglas County: --Schmoker noticed a Lesser Black-backed Gull at the Plum Creek 
delta at Chatfield Reservoir on Nov 6. 
El Paso County: --Luck banded two more Swamp Sparrows at Clear Springs Ranch on 
11/7. 
Fremont County: --Moss also reports another female Williamson's Sapsucker at 
Centennial Park in Canon City. Other locales where Williamson's Sapsuckers have 
been located in "The Climate Capital of Colorado" include Lakeside Cemetery and 
Rouse Park. Two male Williamson's Sapsuckers were at Lakeside Cemetery on Nov 
6. 
 
Huerfano County: --The Neldners saw and photographed a female Eastern Towhee on 
Nov 6. It was still there on the 8th. It was joined by a NORTHERN PARULA on the 
8th!. This is a classic example of the "Patagonia Picnic" effect. Birders are 
invited to check out this hotspot at 151 County Road 359 in La Veta.   The 
Nelders reported that EASTERN TOWHEE was seen again on November 9.--On Nov 4 
Silverman and Percival found a Red-necked Grebe and a Pacific Loon at Lathrop 
State Park (they were still there on Nov 7) and at Horseshoe Lake were a Surf 
Scoter and a Winter Wren. 
 
Jefferson County: -- A Golden-crowned Sparrow continued at the Red Rocks 
Trading Post through Nov 7. A White-throated Sparrow was last seen there in 
late October and seen again Nov 7. --A CURVE-BILLED THRASHER was found by 
Chavez on October 27 at the Red Rocks Trading Post and has been seen daily 
through Nov 9.Sanders reported the thrasher on November 9.
--The Schmokers, pere & fils, saw a Northern Goshawk and a Northern Shrike at 
Red Rocks on Nov 6, so a visit there can be worthwhile even if one does not see 
each of the sparrows and the thrasher. -- Semo and Erthal independently found a 
Tundra Swan on Standley Lake in northern Jeffco. It was found Nov 5 and was 
independently not seen on Nov 6. --About 1:15 on Nov 8 Bob Andrews, Michael 
Kiessig, and Mike Henwood found a "Stub-tailed" Wren, as a PACIFIC WREN, in the 
Wheat Ridge Greenbelt. "It was south of the foot bridge, near the downed logs 
along the little creek below the stairs coming down from the subdivision above. 
This is on the south side of Clear Creek and almost directly south of the 
parking lot in the Wheat Ridge Greenbelt off of 44th." (This area used to be 
known as the Tree Bridge Trail). Their ID was PACIFIC WREN "because of the dark 
color and rapid call notes." The call sounded "exactly like the Pacific Wren 
call on Stokes." (pers com)  This would be the first Jeffco record if accepted 
& one of a few Colorado records. If someone can get photos and/or tape 
recordings of the wren, it would be most helpful.   The wren was heard on 
November 9 but not seen by several birders.
Lake County: --On Nov 6 Kalmach reports 3 TRUMPETER SWANS at the extreme 
western end of Twin Lakes. 
 
Larimer County: --On Nov 4 Dunning detected 3 Three-toed Woodpeckers in Rocky

Trail. That site is about 1.3 miles above the Lawn Lake Trailhead. --Fossil 
Creek hosted a male Eurasian Wigeon at the far west side (seen again on Nov 6) 
and 2 Black Scoters on Nov 5, (not seen on Nov 6), discovered by Bruening. Wild 
noted a Surf Scoter there on Nov 5 and a Pacific Loon on Nov 6. At Horseshoe 
Lake Wild had a Red-necked Grebe, at Boyd Lake a Pacific Loon and at Tinmath 
Reservoir, four adult Lesser Black-backed Gulls and a Mew Gull on Nov 6. 
Logan/Sedgwick: On Nov 8 Sanders ID'd all five of Colorado's most expected 
geese species at Jumbo Reservoir. 
Mesa County:  --Arnold found a DUNLIN in Grand Junction. The site was at Green

Nov 3. Petersen saw two YB Sapsuckers there on Nov 7. Percival saw it again 
with a NASHVILLE WARBLER. That warbler was seen again on Nov 8 in an 
insect-infested oak tree near the Ravine in the eastern end of Pueblo City 
Park, along with a swirl of more common birds. The sapsuckers were not seen on 
the 8th. --Wild found a Red-necked Grebe at Pueblo Reservoir off the West 
Fishing Road on Nov 8.
