[cobirds] Election Day Results: Lake McIntosh: Boulder County

From 10:30am until 12:30pm, I scanned Lake McIntosh in NW Longmont (Boulder County).  I didn't find anything great on the lake, just high numbers of birds I haven't seen for a while and some that are lagging behind a little. 

On the lake:
79 American White Pelicans
75 Bonaparte's Gulls (I tried really hard to make them into Little or Black-headed Gulls with no luck)
33 Eared Grebes
12 Horned Grebes
3 Buffleheads (my FOS)
7 Common Mergansers (my FOS)
10 Common Goldeneyes (my FOS)
and more of the regulars.

The BEST birds of the day though showed up as I was leaving.  I heard a flock of birds that I expected to be Pine Siskins (American Goldfinch-like calls).  After finally getting on them (they were crafty at hiding), I had a flock of 8 COMMON REDPOLLS (new county bird for me).  They altered their calls a lot while I was watching them, from the Siskin/Goldfinch like calls to a rattle reminiscent of a lapland longspur rattle, but longer.  They were located on the shore edge near the southeast boat ramp.  Great looks including one with a really strong reddish hue to the breast.  These were likely my best views of Common Redpolls since I was a young kid (probably 23-24 years ago) when my dad banded some Redpolls in our backyard outside of Philadelphia, PA.
