It鈥檚 April, but Great Horned Owls have been busy at their nests for two months. Golden Eagles are on their nests as early as the beginning of March. And Red-tailed Hawks begin to lay eggs early in that same month, as well. Of the birds familiar to us, most don鈥檛 even think about breeding until April. So why do these large birds of prey begin this annual event so early?
Hear that mouse? There鈥檚 the answer. It takes a long time to raise a baby hawk or owl to the size at which it can fend for itself. Even though both parents are hunting for and feeding them, such large birds grow slowly. So by beginning to nest early, the hawks and owls fledge their young by the time spring arrives. This is just about the time young rodents and rabbits are leaving their nests in great numbers. The young birds, 鈥榯hough inexperienced in catching their own meals, have a lot of potential prey to make their hunting a bit easier and their survival more likely.
