Addendum: Boulder CBC Yesterday

[Bill Schmoker]

Additions to my report on noteworthy birds from Sunday's Boulder CBC:

- Mew Gull (seen at Boulder Res, 2 prior Boulder CBC records)

- Mexican Mallard (Not a species-level addition but first record of this taxon for the count.  Seen on access-restricted portion of Boulder Creek.)

Thanks again, Crew!

Folks- Yesterday saw the 76th running of the Boulder Christmas Bird Count.  We fielded 32 teams who for now have reported 108 species for the day (plus 3 count-week additions.)  There are a few teams that I haven't heard back from yet so I'm still hoping a CW species or two might upgrade to count-day status or that another unaccounted-for bird comes in.  

We added three new species to our all-time list- Say's Phoebe (which previously had been recorded on count week), Pacific Loon (2 birds, one each on Valmont & Boulder Reservoirs), and Hammond's Flycatcher (the second recorded on a Colorado CBC.)

Other rarities for the Boulder Count were Blue-gray Gnatcatcher (seen on 1 prior count), White-winged Dove (2 prior), Red-necked Grebe (three birds on Valmont Res) & Common Yellowthroat (3 prior), Common Loon & House Wren (4 prior), Greater Scaup (5 prior), Ross's Goose (6 prior), and Fox Sparrow (10 prior and perhaps our first Slate-colored ssp.)

Undoubtedly the run of mild weather contributed to many of these unusual birds lasting through the count, and almost all of the water in our circle was still unfrozen.  We'll likely see big changes on future colder counts as the Valmont Power Plant is now decommissioned and will no longer circulate warm water in the Valmont Reservoir complex.  

Thanks to the territory leaders, participants, and feeder-watchers for your bird-finding talents and to the amazing crew who organized and set up our compilation potluck!
