Natural History Field-Excursion: Migrating Raptors over Chelan Ridge

December 17th, 2017 | Posted by in Field Excursions

This post is the first of a 3-part series describing graduate students’ ten-day field excursion to the Methow Valley, as part of their fall Natural History Course. Below is writing by Brendan McGarry, graduate student in the North Cascade Institute’s 17th cohort

The first thing I saw when I opened my eyes was frost coating the inside of the rainfly. I could hear the crepuscular stirrings of my fellow campers, and gave myself a silent pep talk to get moving despite the chill. This was going to be an exciting day after all, we were here to see raptors. 

My cohort and I were part way through the field section of our Natural History of the North Cascades course when we trundled up to Chelan Ridge Hawkwatch Station. It was only October, but we’d seen the hints of winter coming to the high places. The hawks we hoped to see migrating were another hint that the seasons were changing.

The Chelan Ridge Hawkwatch station was established in 1998 in a partnership between the Okanogan-Wenatchee District of the US Forest Service and HawkWatch International. The goal was to learn more about the raptors migrating through Washington, down the Pacific Coast Flyway. Here, starting in late August, ending in late October, intrepid biologists scan the skies, and count hawks. With luck, they also lure them into traps to band the birds and release. While we were grumbling about the cold, they were already out doing their jobs.

The first bird, an immature Cooper’s Hawk that zipped by during breakfast, was spotted by Kent Woodruff. This was apt because he was our host. Kent, a retired Forest Service biologist who established the station, was full of stories about the wildlife of the North Cascades. Yet, never was he more animated than when he spoke of the birds overhead.
