—On Dec 30 (the young male was seen again Jan 2) 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

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 Jan 1 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.

--On Jan 2 an adult Northern Goshawk was observed and photographed by Dave
Leatherman at Grandview Cemetery in Ft. Collins.


—On Jan 4 a Golden-crowned Sparrow was reported at Grand Junction Wildlife
Area. First reported on Dec 28 by Mike Henwood.

—On Jan 4 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 Jan 1 a juvenile “kumlien’s” Iceland Gull was reported at Pueblo
Reservoir at South Shore Marina. It was first reported by Brandon Percival
on Dec 26. 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 twenty something winters
at Lake Pueblo (nicknamed “Murray”) is here again. See eBird for most
recent sighting (Jan 4)

Nature Center. It was found by Brandon Percival and Chris Knight near the
Pueblo West pit along the Arkansas River on Jan 2. It may be the same bird
seen in November.
