Central Flyway Broad-winged Hawk Project Update
We've found five active Broad-winged Hawk nests in the Duluth area over the past month and several others outside of the city. It appears that the eggs from nests in Duluth have hatched over the past two weeks, but we have yet to see the nestlings. One clue that hatching has occurred is a change in the behavior of the incubating female. Instead of sitting low in the nest, the female often sits slightly higher and may squirm or shift as nestlings move beneath her. Can you spot the adult hawks hidden in these nest photos?
Female Broad-winged Hawks are remarkably quiet and well-camouflaged while on the nest. Most of the time, only a watchful eye peeking through the vegetation gives away their presence. The best opportunity to hear them is during prey exchanges. The male will bring food near the nest and call to its mate. The female on the nest carefully assesses whether it is safe to leave before retrieving the prey and returning to the nest. So far, we have observed adults delivering snakes, red squirrels, and small mammals.
We will continue monitoring nests and searching for new ones through early July. At that time, researchers from Hawk Mountain will join us to deploy transmitters on nesting adults. Hawk Mountain has been conducting similar research for more than a decade and brings extensive experience and expertise to this effort.
