Bald eagles will add to their old nest each year for that year's nesting til the weight of the nest causes it to collapse.
Well, in 2007 the bald eagles were removed from the endangered species list, the lower point of bald eagles was 417 breeding pairs, it is now estimated that there are over 10,000 breeding pairs with at least 1 mating pair in each state. In some other answers it says there are 47,000 bald eagles left. Now the bald eagles are listed with a status of "threatened".
Bald eagles build large nests of sticks and small tree limbs. They add to the nest each year until it collapses.
Bald eagles nests are large collections of sticks and tree limbs, added onto each year. Can sometimes weigh nearly a ton in extreme cases.
Bald eagles make a nest of sticks, returning each year and adding on til the nest can weigh nearly a ton.
Insects communicate with each other by sensory.
I do not know how Jaguars communicate with each other. They might growl or purr.
