[cobirds] Silverthorne birding, 3/17

Went up to the mountains today for some St. Patrick's Day birding.  Was hoping to find Barrow's Goldeneyes still at the Blue River Water Treatment Plant, but no dice.  Numbers of ducks there were down 90% from four weeks ago -- just a couple of Mallards, Gadwall, and Ring-necked Ducks.

Some private feeders in a residential neighborhood in Silverthorne saved the day.  In addition to lots of the usual birds, I saw:

Pygmy Nuthatch (I don't think these are common in Summit County) - 2
Pine Grosbeak - 10+
Cassin's Finch - 10+
Evening Grosbeak - 20+
Brown-capped Rosy-Finch - ca. 12
Gray-crowned Rosy-Finch - ca. 12
Red Crossbill - several pairs seen (or the same pair several times)?  The ones I got recordings of were Type 5 (ID confirmed by spectrogram), which is the type expected at that elevation.

Good birding, all --
