In Massachusetts, Great Horned Owls typically start nesting in the middle of February, raising their families in the later stages of winter. The female will incubate the eggs while her mate brings her food. Within a month, up to five eggs will hatch and the owlets will be closely guarded by their parents. Six weeks after hatching, the owlets will leave the nest and walk around. In another three weeks, the young owls will already have learned to fly. The parents will continue to feed and care for their offspring for several months, often as late as October. It is wise to stay away from young owls and their nests as Great Horned Owls are not afraid to attack if they feel their family is threatened!
