Another by-bike winter bird species!

A windy day in Madison today.  I biked a total of only about three miles, but saw some cool (cold?) landbirds:  a small Falcon on a telephone pole, a too-distant buteo, and a flock of about 20 of a certain winter-only bird.  Any guesses as to what all these birds were?  Location is not important.  Email me with your ideas...
