Reproduction The Crowned Solitary Eagle is a monogamous species. Between August and October, a single white egg with grey spots is laid on a platform-like nest of sticks and leaves. The nest is constructed on the tallest trees of breeding territories, 10-13m above ground. Some eagles have been seen nesting on human made buildings in area where no trees were available. The egg hatches around 45 days after it was laid (November-December). The female stays near its offspring from the moment the egg is laid until the chick is old enough to be left alone for short periods of time. The male continuously brings food to the nest, while the female joins the hunting when the chick hatches and grows a bit. The offspring will stay in the nest for 65-70 days. Not much is known concerning the age of breeding, but it is estimated that they do not breed before they reach 3-5 years of age.
