[cobirds] Boulder County, more arrivals

Cobirds:
This is mostly for today, but a few from yesterday also.
Bumped into Peter Gent at Gregory Canyon, as mentioned earlier in his
post. Here's a more detailed list of what's staring to come back;
highlights include:

Gregory Canyon and a bit of Flagstaff Mt Trail:

House wren - 4 - singing
Blue gray knatcatcher - 2
Black headed grosbeak - 3 - singing
Gray catbird - 4 - singing
Yellow breasted chat - at least one singing
Virginia's warbler - 2 singing
Broad tailed hummingbird - all males - 7 - numbers increasing
Spotted towhee - 12 - singing males - numbers increasing
Lazuli bunting - 4 - all singing males
Empidonax flycatcher ssp: - 2 down by the road, distinct "teardrop"
shaped eye ring, a lot of olive in the back, no tail flicks - without
the song, I won't call it. But would guess Cordilleran.
Western meadowlark - 1 - singing up by the "Bowl" on Flagstaff Trail


Walden \ Sawhills complex: (Note: boardwalk still not complete -
work drags on and on. During weekdays the heavy construction at the
gravel pits drowns everything out - really obnoxious. And the airport
nearby has non-stop planes roaring overhead. The suggestion: get
there really, really early to avoid the noise.)

Great tailed grackle - two persist around Cottonwood Marsh
Marsh wren - at least one singing at the end of the boardwalk
American bittern - 1 heard at Cottonwood Marsh
Bullock's oriole - 4 - all males, all singing
Warbling vireo - 2 - seen and heard
Yellow rumped warbler - 4
Yellow warbler - 3 - all males, singing
Spotted sandpiper - 6 - seems to be one at every lake
Eastern kingbird - 1
Yellow headed blackbird - 6 - numbers increasing
Red winged blackbird - everywhere - must be several hundred
Cedar waxwing - 2
Western painted turtle - 6
Northern water snake - 1 - in Boulder Creek near 75th st. - being
attacked by red-w blackbirds

Centenial Middle School neighborhood, Boulder:

Cedar waxwing - 12
Bushtit - 2
House wren - 6
Say's phoebe - 1

Leaves and wildflowers are 4 to 6 weeks early. Birds are right on
time, despite the greenery and insect hatches. More blooming:
hawthorn, chokecherry, yucca, meadow salsify, butter and eggs
(toadflax), lavender penstemon, gromwell (puccoon), blue flax, golden
banner.

It looks and feels like mid-June. The greenest I've ever seen it, in
early May. We'll be in trouble though, if we don't get some
moisture. It'll be interesting to see how the birding plays out in
the next couple of weeks. - John Tumasonis (John T), Louisville
