—On Dec 29 a Rusty Blackbird was reported at Bear Creek Lake Park. First reported Dec 23 by Robert Raker.
LARIMER COUNTY:
—On Dec 30 two Yellow-bellied Sapsuckers were reported in Fort Collins at Grandview Cemetery. One is a young male and has been reported south of the Trolley House several times in different trees. Last reported by Dave Leatherman "in a medium-sized deciduous tree due south of the Trolley House out on City Park Nine golf course. This tree has a white tag on the north side about 7 feet up that identifies it as a tree I've never heard of called "Pacific Sunset Maple". This is a hybrid between Acer platanoides (Norway maple, a widely planted native of Europe) and A. truncatum (Shantung maple, native to northern China). The tag also says it is the horticultural variety called "Warrenred".
The Trolley House is the westernmost building on the south side of Mountain Avenue just east of the cemetery entrance. There is an east-west row of 10 or so Scots Pines that runs from the sw corner of the building w toward the golf course. It seems the bird spends a lot of time in those pines and retreats out into deciduous trees on the golf course (between the Trolley House and the softball fields to the south). This young male was first reported by Dave Leatherman on Dec 23.
The other Yellow-bellied Sapsucker is an adult that favors Austrian pines just east of the gray portapotty midway along the southern cemetery boundary road and often retreats to the big cottonwood just east of the pines. This adult male is probably the same bird reported by Fawn Simmons on FC CBC, Dec 14 and seen periodically in the cemetery since mid November.
—On Dec 26 a Gyrfalcon was observed near the Larimer County Landfill in SW Fort Collins. First reported by Robert Beauchamp on Nov 3. This is the same location a Gyrfalcon spent much of last winter. Please post updates to COBirds.
MESA COUNTY:
—On Dec 30 a Dunlin was reported at Horsethief Canyon State Wildlife Area on the shoreline of a gravel bar on the Colorado River. First reported Dec 28 by Douglas Diekman.
—On Dec 29 a Golden-crowned Sparrow was reported at Grand Junction Wildlife Area. First reported on Dec 28 by Mike Henwood.
—On Dec 27 a Wilson's Warbler was reported at Grand Junction Wildlife Area, in willows along the Colorado River, by Mike Henwood.
PUEBLO COUNTY:
—On Dec 30 a juvenile "kumlien's" Iceland Gull was reported at Pueblo Reservoir on the Sandspit at the boat ramp at South Shore Marina by Brandon Percival. Although it's no longer recognized as its own species by the AOU, and has been combined with Thayer's Gull, it is rare in CO.
—A Great Black-backed Gull that has spent the last umpteen winters at Lake Pueblo (nicknamed "Murray") is here again. See COBirds for most recent sighting (Dec. 30)
It's Christmas Bird Count time across Colorado, between Dec 14 & Jan 5.
