CoBirders,
I went to McIntosh Reservoir this morning (
http://coloradocountybirding.com/county/bird_a_county.php?name=Boulder#356) looking for the reported goodies (Long-tailed Duck, Barrow's Goldeneye, and Lesser Black-backed Gull). Found only one of the three. There is a huge flock of Common Goldeneye in the middle of the lake that is being followed by most of the gulls. Keep your eyes peeled for the three female Barrow's out there by looking for the females with all yellow beaks. Full list follows.
