Our Raptor Ecology and Conservation Team (REACT) is running North America’s largest Ferruginous Hawk nest monitoring program. In order to study Ferruginous Hawk ecology and potential cumulative effects, we check on hawk nests once a week to compare nest success across the Canadian Prairies.
We use an extendable painter’s pole with a camera mounted on the top to peer into nests. We call them our “Tree Peepers”, trademark pending. This method is effective and fast, thereby reducing disturbance to the nest. Check out the video below to see how’s it done.
We check on nests until the young fledge (i.e. naturally leave the nest) or until the nest is done. If the nest didn’t fledge any young, we record reasons for failure. Was it predated? What kind of animal was the predator? If the nest was successful, then we record the number of young fledged, when they left the nest, and other similar data.
All the data goes into our huge database (cue computer noises) and is readied for our analyses.
