171. Bridger Mountains Hawk Watch, Bozeman, Montana

A ridge at 8,520 feet elevation that thousands of Golden Eagles fly past each fall.

This is the premier location in the lower 48 states for observing migrating Golden Eagles in autumn. Up to 1,800 eagles have been observed in a season, and more than 500 have been tallied in a day!

Seventeen raptor species pass through the area each autumn. The migration begins in earnest in mid-September, and non-eagle activity reaches a crescendo in late September and early October. We count the greatest number of Golden Eagles in mid-October. Bright sunshine, warm temperatures, and strong southwest winds, which usually occur one to two days ahead of an approaching cold front, make the best conditions for seeing a large number of raptors.

I always enjoy the vigorous hike required to reach the summit and observation point, as well as the anticipation of the day’s flight. One never knows what will fly by, and the 360-degree view of the surrounding mountains is awe-inspiring; it’s worth the effort all by itself. Many outdoor enthusiasts visit, and I enjoy sharing the day’s highlights with them.

I also love watching the resident mountain goats, and some visitors have seen black bears and cougars. — Steve Hoffman
