Bonny,
We have no cliffs here so their nest will have to be in a tree I suppose.
I read that they usually lay 2 eggs but only 1 Eaglette usually survives as one will push the other from the nest in a battle for food.
I also read that the adults will lure the babies from the nest with food to teach them to fly, allow them to return to the nest through the summer months but then kick them out at the end of summer.
Also that they will sometimes snatch geese in flight for food! Wow! Said the Eagle gets under the goose, turns upside down and grabs the goose.
We have herons and egrets around here, so I guess their babies will be at risk!
This could be an interesting Spring and Summer if I get out there watching for things!
