This evening I was hiking at the mouth of Sunshine Canyon in Boulder when I heard the whistled "Pee-tee" call of a Broad-winged Hawk. After looking a bit I saw a juvenile Broad-wing perched in a stand of narrowleaf cottonwoods. The unseen adult was calling from somewhere else in the stand. Broad-winged Hawks breed in small numbers on the Front Range but it's always exciting to run into a family group.

This was only about 100 yards up Sunshine Canyon Road from the Mt. Sanitas Trailhead.

Dave Leatherman alerted me that my apparent breeding record of Broad-winged Hawk might be rarer than I thought. No confirmed breeding records were reported during either Breeding Bird Atlas, and Andrews & Righter mention only one confirmed record of breeding for the state. So I hope people can obtain additional confirmation of this apparent family group.

We had very good looks this morning of the adult Broad-winged Hawk from the Centennial Trail parking lot at the mouth of Sunshine Canyon, Boulder. The hawk was perched for a long time on top of a pine tree across the road from the parking lot.

Both the adult and immature Broad-winged Hawks were seen this morning (July 29) at the mouth of Sunshine Canyon, Boulder.
At 11:05 both birds were flying low over the riparian area between the Centennial Trailhead parking lot and the start of 
the Mount Sanitas trail system to the east. The immature perched briefly on top of a pine tree on the south side of Sunshine 
Canyon Drive. Serious flying practice looks to b underway.
