Three peregrine falcon chicks hatched over the weekend in the nest box on the 14th floor of One Capital Center in downtown Boise.
The chicks weighed about 1½ ounces (40 grams) when they emerged from their shells. They will be full-grown when they leave the nest and by the time they fledge in July, the little fluff balls will be 18 inches tall and have a wingspan of more than 3 feet.
The adults will brood the chicks for about 10 days, depending on the weather. The young birds are not yet capable of regulating their own body temperatures, so they need the adults for warmth. The young ones also can huddle together to keep warm.
