How long does it take for Bald Eagle eggs to hatch?

Bald Eagles are monogamous and mate for life. Together they build their large nest, called an eyry, at the top of a tall, sturdy tree or they may also nest in a cliff or on the ground in treeless regions.

A new nest averages 2 feet deep and 5 feet across. They are lined with twigs, moss, grass, and feathers. The nest becomes larger each year as the eagles return to breed and add new nesting materials to shore up the old nest. Eventually, some nests reach sizes of more than 10 feet wide and can weigh several tons.

Breeding bald eagles typically lay one to three eggs once a year, and they hatch after about 35 days of incubation. Hunting, egg sitting, eaglet feeding and brooding duties are shared by both parents. The young eagles begin flying three months after hatching and are on their own about one month later.

We have an Anerucab Bald Eagle nest that we are so lucky to observe every day. It is about 60 feet off the ground high up in a big pine tree nestled safely between thick limbs. It is about 5 feet wide and at least two feet deep. The mother, most of the time remains in the nest, while the father hunts and brings food. We cannot see the eggs but love to watch the the parents take care of the nest. It is thrilling and consider ourselves very lucky for this experience.

I live in East Texas and my husband and I have been watching a Eagle's nest in our area. Recently we noticed an Eagle in the nest. Then about a week ago we noticed the nest was gone. The tree that the nest was in was an old tree and the tree limbs that the nest was in broke and the nest was on the ground. I went and took a look and found pieces of egg shell in the mounds of grass and twigs on the ground. My question is will the pair of Eagles return and build a new nest or some where else? And will they lay another egg?

Research has found that the basics in nest construction are instinctive primarily, but birds’ nesting skills improve through trial and error. If this eagle nest failed, they will move on to another location and try again.

When an eagle's egg begins to crack, how long does it take before the eaglet is fully born?

There is a live eagle cam on Minnesota Bound's website if anyone is interested.
