--At Valmont Reservoir, on December 6, Mlodinow is viewing a RED-THROATED LOON. He is viewing it from the City of Boulder's Open Space and Mountain Parks Annex off of 75th St. This would be the east end of Valmont which is not really all that visible from the Legion Park Overlook. The RED-THROATED LOON was associating with Western Grebes.

Denver County:

--7 TUNDRA SWANS were reported by T. Jones  at Marston Reservoir on December 13, on the west side of the lake, off of Old Wadsworth Blvd. next to the wire fence They were in a group. All  were in Ad. plumage. The Swans were bobbing their heads up and down, continually, the whole time they watched them. They were in the middle of the lake and then were in the south part of the lake and flew once. The swans were seen around 4pm. You could see how the eye looked separate from the bill somewhat, unlike in a Trumpeter.  

--A juv White-winged Scoter was reported by Tina Jones at Marston Reservoir on November 22.  On December 14, T. Jones relocated the White-winged Scoters in the northern section of Marston Reservoir. Tina recommends when viewing birds at Marston Reservoir, please beware of signs in this area especially if viewing from the SW,  PLEASE let's not give birders a bad name and PLEASE watch the birds from the sidewalk or right next to the sidewalk.    

 

El Paso County:

Fremont County:

--On December 11, R. Miller reports 8 TUNDRA SWANS in the east Valco Pond on MacKenzie Ave. in Canon City. S. Moss also saw the TUNDRA SWANS on December 11.  She recommends if coming to see them if they are out on the pond that viewing will be very difficult, as the ponds are on private property, access past the gates and fencing is trespass.  Walking along the road, (very busy) traffic, driving 50 mpg. to try to see them will be difficult. There is not much room to walk along the road and the irrigation ditch. S. Moss reports the TUNDRA SWANS were flushed from the pond yesterday. "They circled higher and higher as if they were leaving the area." Swans were not seen by S. Moss on December 13.

--On December 9, S. Moss found a YELLOW-BELLIED SAPSUCKER at Veteran's Park on Hwy 50.

Weld County:

--On December 11, Mlodinow reports seeing 1 Common Redpoll at the southeast corner of Union Reservoir.

--On December 13, N. Lewis reports a flock of 30 Common Redpolls at the office/maintenance facility up the road to the north of Crow Valley. The birds were hanging around the north side of the property around a row of junipers.  They spent most of their time perched in a couple of dead trees by the junipers, and didn't seem to be doing any feeding, just perching.  During the hour I followed them as they moved from tree to tree (they would perch in the tree nearest the road, flush every time a vehicle came by, fly to the farthest tree, and then return to the original tree.  No one ever said finches were all that bright), they did no feeding, although they did visit a small patch of snow to "drink". They seemed to be staying in that area and may be "chaseable".
