CU Preston: ""During our study period, which is primarily from March until August, we're looking at the reproductive cycle of eagles, and so what we're doing now is checking to see how many nests are active, and every month or so we do aerial surveys to try to determine if the nests are still active and if so, how many chicks are in the nests and what's going on around those nests, so we have the nests mapped. We're coming in right now. As a matter of fact we're finding that the chicks are 13, 14 days old. The female is brooding the chicks, staying very close by. The male is out gathering food. He'll bring the food into the nest. Usually he won't bring it directly to the nest of the chick. He'll bring it to the female. The female then will bring it to the chicks, tear it up a bit, and fee them that way. By the time they're about 25 to 27 days old, they'll be able to tear the food themselves. Later in the season , we'll find that the femail will spend less and less time with the chicks as they grow larger toward the time that they leave the nest, when they fledge, the adults will spend very little time nearby
