[cobirds] Wilson's Snipe, ID help,Jefferson County

I spent a day at Chatfield SP during the snow storm. Amazing number of birds lifting off from all the road sides. Due to the fact that they moved away from you and poor visibility through the falling snow, it was a challenge to ID. So, I drove around with my windows down and the heater up!

There are a couple birds I would like some ID help. While photographing the Wilson's Snipes(2) a flock of 15 possible Yellowlegs landed near by (Greater/Lesser?). Also, a possible Pipit needs ID. I have images of both and I would appreciate some ID help. I was able to photograph most of the birds on the list. jhyypio@earthlink.net re:yellowlegs
