Chris Martin, a bird biologist, checked the nest and found that two chicks had hatched. Another egg was starting to hatch. The nest is in a special box on the 13th floor of a building on Elm Street. The box was built by humans and put there 10 years ago. These are the first chicks in 10 years to be born.
Scientists are very excited because the peregrine falcon is an endangered bird on the state's list.
Then they'll stay around the nest for several weeks after that. Peregrines are known for their fast-flying hunting skills. The parents of the chicks are the first in northern New England to make a nest on a human-built structure. This spring is shaping up to be a very good year for New Hampshire's peregrine falcons. There are now 11 peregrine falcon sites in the state with eggs that will soon hatch.
