Peregrine falcons have made their annual return to Minnesota Power’s Hibbard Renewable Energy Center in Duluth and Boswell Energy Center in Cohasset, and viewers can tune in again to “Egg Watch” on the company’s FalconCam to watch peregrine parents care for their eggs.
The falcons are caring for four eggs at each site this spring. According to the Cornell Lab of Ornithology, the incubation period is between 29 and 32 days, which places hatching at Hibbard in early May and at Boswell about a week later.
Peregrine falcons were once threatened with extinction due to the use of pesticides before being removed from Endangered Species List in 1999.
