Chelan Ridge Fall 2019
The Chelan Ridge HawkWatch is a collaboration between HawkWatch International and the USFS Okanogan-Wenatchee National Forest. In our 22nd season of monitoring, counts typically range between 1,600-2,100 migrants of up to 17 species per season. The most commonly seen species are the Sharp-shinned Hawk, Red-tailed Hawk, Cooper's Hawk, Northern Harrier, Golden Eagle, and American Kestrel . We also band raptors at this site and provide opportunities for visitors to learn about the diversity of birds of prey in the area, migration monitoring as a conservation tool, and what we can learn from trapping and banding efforts.
Directions
The Chelan Ridge HawkWatch is located on the Okanogan-Wenatchee National Forest, approximately 13 miles northwest of Chelan, WA. From Wenatchee: go north on Hwy 97 past the Chelan turn-off to Milepost 244. Turn left at the Apple Acres Road sign and drive 1.5 miles. Turn right on Antoine Creek Road which turns into NF-8140. On the ridge top, go right at the T intersection on NF-8020. Keep right for another mile to the second parking area. From here, look for the trailhead sign and hike approximately 0.75 mile north following the flagged trail to the lookout area.
HawkWatch International
The mission of HawkWatch International is to conserve our environment through education, long-term monitoring, and scientific research on raptors as indicators of ecosystem health.
