Cassin's Finches and Redpoll flock, Larimer County

[Luger]

Just had a large flock of Cassin's Finches move through my neighborhood. We were able to count 23 but there were probably more. With them were at least four Common Redpolls. They were in the area for about ten minutes in the tops of large elm trees. We live 1/2 mile south of Horsetooth Mtn Open Space. The flock was last seen moving east.
