Gunsight Mountain Spring HawkWatch 2021

We’re excited to announce that migration is on once again this spring at the Gunsight Mountain HawkWatch in Alaska—North America’s northernmost migration monitoring site! This valley count is known for large Red-tailed Hawk and Golden Eagle counts, but also sees a good flights of Rough-legged Hawk and Northern Harrier; these 4 species comprise nearly 80% of the average yearly flight. Many of the Red-tailed Hawks are of the stunning Harlan’s subspecies, and light reflecting off of snow cover creates amazing looks at raptors flying overhead.

Directions

Drive NE on the Glenn Highway (route 1) from Anchorage. Highway will travel through towns of Palmer and Sutton. At MP 120 there is a vehicle pullout on the right hand side of the road. That is the primary watch site (April 1 - May). Early season counts (March 7 - March 31) are conducted at a trailhead parking area on the left hand side of the road just past MP 121. Anchorage Audubon Society and Mat-Su Birders conduct an annual Hawk Watch Weekend in mid-April at the large MP 118.8 pullout on the right hand side of the road. Just before the 118.8 pullout is a left turn to a larger parking area and outhouse. Drive time from Anchorage is approximately 2.5 hours. Winding road, rock falls, cliffs, gorgeous scenery.

HawkWatch International
