Dave Leatherman least)
I will be in the extreme southeast corner of the cemetery with my
scope set up southeast of the pumphouse most mornings between 8 and
noon. Birders who want to see the crossbills would have a decent
chance if they come mid-morning and are willing to spend at least an
hour. The visitation of the nest by the male, brief feeding session,
and various post-feeding activities by the male (which could include
seeking water on the ground) are the only real chances to observe the
male and on average take a total of about 5 minutes. When these
activities are over, there's nothing to see but less-than-satisfying
views of the mother's back or wing atop a 2 x 2-inch visible section
of nest for another hour until the male returns. Visitors should note
the real potential for golf ball damage to vehicles if they park near
the corner. When you first get there, figuring out where the spot is,
parking somewhere else, and walking over to the corner would probably
be best. Remember not to park on the grass, block roads, or
otherwise interfere with the cemetery operations. The cemetery and
golf course staffs are being very patient and accepting. We need to
keep on good terms with them.
Montrose County:
--Dexter reported that 2 Black Phoebes have returned to the Uravan
bridge on March 21.
Pueblo County:
--A Sage Sparrow was reported by Percival on the road at the SWA in NW
Corner of Pueblo Reservoir on March 26. The bird was singing on top
of a bush, 1.2 miles down the road from the turnoff, before you get
into Lake Pueblo State Park, coming from Pueblo West.
Weld County:
--2 ICELAND GULLS (1 "almost-definitive" adult "Kumliens" Iceland, 1
first cycle), an adult Glaucous Gull, and 3 Thayer's Gulls (1 adult.,
1 first cycle, 1 second cycle) were reported by Komar at Windsor Lake
on March 27. This is in Weld County, just north of Main Street in
downtown Windsor. Great views of gulls from the swim beach on south
side of lake and from fishing pier on west wide. Easy access by car.
Telescope not required for gulls along shore, but many more on center
of lake.
--A first cycle ICELAND GULL and a first cycle Thayer's Gull were
reported by Bruening at Windsor Lake on March 28. An adult Lesser
Black-backed Gull was reported by Miller at Windsor Lake on March 28.
