[cobirds] Long-tailed Duck, Rocky Mtn Lake, Denver county

COBirders,
I dropped by I-70 & Lowell and confirmed Bob Canter's Long-tailed Duck amongst the white caps this morning around 10 am.  It was hanging with Ruddy Ducks.  It appears to me to be a female that hasn't quite completed the molt into alternate plumage but my experience with this species is also limited so I can't be sure if it is leaving juvenal plumage or just basic plumage.  The wind sure didn't help either as she stayed tucked most of the time. 

As windy as it was, there were also quite a few swallows (200?) on the lake.  Most were Cliff and Barn with at least 2 Northern Rough-winged and more Violet-greens than eBird liked (at least 8.)  No Tree or Bank Swallows that I could discern.  A few usual suspects brought the list to 19 species in 20 minutes.

Happy spring,
Chip Clouse
Olde Town Arvada, CO
