Raising Bald Eagle Eaglets - Nurturing to Learning to Fly (Fledging)!

Описание: How quickly do the eaglets grow?
The eaglets grow rapidly, they add about a half pound to a pound of body weight every week until they are about 9-10 weeks old, depending on if the eaglet is a male or female. Females are always larger.
At about two weeks, it is possible for them to hold their head up for feeding.
At about three weeks they are 1 foot high and their feet and beaks are very nearly adult size.
At about three to four weeks old the eaglets are covered in a secondary coat of gray down.
At about four to six weeks, the birds are able to stand, at which time they can began tearing up their own food.
At about three to six weeks, black juvenile feathers will begin to grow in. While downy feathers are excellent insulators, they are useless and must be replaced with juvenile feathers before an eaglet can take its first flight, some 10 to 14 weeks after hatching.
At about six weeks, the eaglets are very nearly as large as their parents.
At about eight weeks, the appetites of the eaglets is at its greatest. The parents will hunt almost continuous to feed them, meanwhile at the nest the eaglets are beginning to stretch their wings in response to gusts of wind and they may even hover for short periods. The eaglets grow stronger.
At about nine to ten weeks, they begin branching, this is a precursor to fledging.
Around ten to fourteen weeks, the eaglets will fledge, or fly away from, the nest.
Once the eaglets have fledged they may remain around the nest for four or five weeks, taking short flights while their primary feathers grow and strengthen. Their parents will still provide all of their food. The juvenile fledglings, with the exception of their color, look similar to their parents, but are nothing like them in behavior. The juveniles now have to learn to hunt, and they only what’s left of summer to learn. After that, they’re on their own. The first winter is the most dangerous and difficult part of an eagle’s life.
