On Jan 6th, conditions were cloudy and deteriorating as a front approached, with light snow falling and increasing wind. The morning of the 7th was clear and bright and extremely cold.
Description of the Bird
The bird was perched on leafless trees very adjacent to the Poudre River waterway. Wind was picking up and quite cold, so the bird didn't linger long on any particular branch. The plumage was dull brown and spotted on the upperparts, and white streaked with brown strokes on the breast. The bird had narrow banding in the tail and a relatively smallish looking physique for a hawk.
There were no vocalizations.
Similar Species Discussion
A few buteonine hawks, but especially Red-tailed Hawk, Broad-winged Hawk, Swainson's Hawk. As it was clearly a juvenile bird, that is what I considered for comparison.

Numerous adult RSHA seen and heard in California during the years I lived there. Also seen and heard in Florida during several visits. Photographed many times. I've also seen, heard, and photographed RTHA, BWHA, and SWHA. I've spent considerable time in close range to RTHA and SWHA, with birds of a variety of ages during my time as volunteer with the Rocky Mountain Raptor Program.
