Previous winter time White-throated Swifts in Colorado

[Brandon K. Percival]

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.

Climate change might also be a factor.

Hi, all. Here is the "winter" (December-February) range map for the White-throated Swift in the United States:

The multiple records from Arkansas are pretty amazing. A record of 8 birds from Churchill County, northern Nevada, Feb. 25 of this year, likely refers to early migrants, I would think.

Interesting discussion. Great discovery.
