Bent County:
--On March 17, Nelson reports a SNOWY OWL still present at John Martin
Reservoir on the north side. On March 16 Nelson saw the immature female owl
numerous times. It likes sitting atop rocky outcrops on the north side of the
lake about 1 1/2 miles west of Overlook Point. Duane requests that birders be
considerate of the stress the bird might be under, and do viewing from
vehicles and settling for distant views instead of walking for close views.
This particular bird does not allow close approach.
Boulder County:
--The GOLDEN-CROWNED SPARROW continues near the Teller Farm Parking lot on
Valmont through March 11.
--On March 15, Mlodinow found a 1st cycle GLAUCOUS-WINGED GULL at Panama
Reservoir. It is present as of March 17.
--On March 17, Floyd reports a Lesser Black-backed Gull at Panama Reservoir.
Garfield County:
--On March 11, Filby reports 41 Barrow's Goldeneye at Coryell Ranch viewable
from Hwy 82.
Jefferson County:
--The GOLDEN-CROWNED SPARROW at the Red Rocks Trading Post feeders continues to
be seen thru March 15 as reported by Brown.
--Schmoker reports the Greater Roadrunner cruised by the Hawkwatch on March
18, at Dinosaur Ridge.
--Henwood refound the adult and juv Harris's Sparrows on March 12, near the
Boat Launch area at Bear Creek Lake Park.
La Plata County:
--Barrow's Goldeneyes remain on the Animas River. On March 17, as reported by
Beatty, there was an adult female at the second fishing pull-out south from
town as the road descends to near river level. This section of the Animas has
been fairly reliable for Barrow's this winter. However, the mixed Goldeneye
flock spooks easily and then flies up or down river for a quarter mile or more.

Roller confirms they were present on the 12th.

Reservoir.

between the towns of Bovina and Arriba.

Rosy-Finches at residential feeders in Silverthorne.
