[cobirds] Snowbirding in Estes Park, more first of season species, Larimer Co.

I decided to do my usual late ,afternoon walk at Lake Estes today in the cold snow showers. I wasn't expecting any large birds, and saw none other than Canada Goose, Mallard, American Crow, Common Raven, and Turkey Vulture. The highlights were the many small birds feeding in bare areas along the shore and in sheltered areas. Of particular note were a Green-tailed Towhee and two Hermit Thrush, firsts for the Estes Park area this year in eBird and a White-crowned Sparrow, with only one previous eBird report from March. At one point, the Towhee was feeding right at my feet with one of the Hermit Thrush three feet away.


A real treat was seeing many bright Yellow-rumped Warblers (both Myrtle and Audubon's) feeding in plain view along the shore and among the exposed rocks in the water, accompanied by Western Bluebirds, American Pipit, Vesper Sparrow, and Savannah Sparrow.


Worth the freezing fingers, toes, and nose. Of course it was in the 90's today back home in Maryland.

I have reported to you in the past about a partially leucistic Red-winged Blackbird male that has unusual white primaries on his left side. We first saw him in 2010 and he was already at least a year old. Well he is back, and is on the same territory in cattails that he has occupied each breeding season. He is now at least 8 years old. He can be seen just 150 yards north of the 2S and Co Hwy 15 junction just south of Monte Vista. Had a scare when I saw a dead Red-winged Blackbird on the highway, but it was another bird (still sad tho).

Anyone know the longevity record for Red-winged Blackbird?

One inch of snow and still falling. Guess we are getting off easier than the front range...

[cobirds] Boulder creek black-throated grey continues

Was able to find the black-throated grey warbler previously reported along the Boulder Creek bike path (CU East Campus area) this afternoon at about 5pm. It was hanging out with a group of yellow-rumped warblers. Also of interest along the creek path were dippers, hermit thrushes, many chipping sparrows, a Lincoln's sparrow and a green-tailed towhee. 

For those looking for the black-throated grey, it was in an area to the south of the path, near where there is a tree with pink flagging around the trunk.

A big thanks to those who previously reported the black-throated grey! Such a cool bird!

Happy birding,
Laura Steadman

[cobirds] FOS Longmont birds

When my sister told me she had heard Broad-tail Hummingbird up at Chautauqua last Monday, I put my feeders out. Sure enough, I had a FOS Broad-tail on Thursday (5/27).

Today, a Lincoln's Sparrow and Lazuli Bunting both visited my feeders in the snow!

Report submitted by Bird Conservancy of the Rockies (jeff.birek@birdconservancy.org)
Dinosaur Ridge - Bird Conservancy of the Rockies information may be found at: http://www.birdconservancy.org/

Site Description
Dinosaur Ridge is the only regularly staffed hawkwatch in Colorado and is the
best place in the world to see migrating Ferruginous Hawks. Dinosaur Ridge may
be the best place in the country to see the rare dark morph of the Broad-winged
Hawk (a few are seen each spring). Hawkwatchers who linger long enough may see
resident Golden Eagles, Red-tailed Hawks and Prairie Falcons, in addition to
migrating Swainson's, Cooper's and Sharp-shinned Hawks, American Kestrels and
Turkey Vultures. Peregrine Falcons and Ferruginous Hawks are uncommon; Northern
Goshawk is rare but regular. Non-raptor species include Rock Wren, and sometimes
Bushtit, Western Bluebird, Sandhill Crane, White-throated Swift, American White
Pelican or Dusky Grouse. Birders are always welcome.
The hawkwatch is generally staffed by volunteers from Bird Conservancy of the
Rockies from about 9 AM to around 3 PM from March 1st to May 7th.

Directions to site:
From exit 259 on I-70 towards Morrison, drive south under freeway and take left
into first parking lot, the Stegosaurus lot. Follow small signs from the south
side of lot to hawkwatch site. The hike starts heading east on an old two-track
and quickly turns south onto a trail on the west side of the ridge. When the
trail nears the top of the ridge, turn left, head through the gate, and walk to
the clearly-visible, flat area at the crest of the ridge.
