Climate change might also be a factor.

Duane Nelson reports White-throated Swifts in Picketwire Canyon (Las Animas and Otero Counties) on February 28, 2009.  These were probably early spring migrants, though they did make in the "Winter" Season.  So, White-throated Swifts have been seen in Colorado, all 12 months of the year now, except for January.  I'm not sure before this year, they had been seen in November or December in Colorado.  White-throated Swift seem to be more hardy birds, then we might think.  A swift in Colorado in the "winter" is still pretty amazing.

The known winter range in the US, is southern New Mexico; southern Arizona; El Paso, Texas; and in California.  I wonder if they actually winter further north, then is known.
