May 18.
First night without adult eagle in the nest.
Romme from 2020 left the coasts of Germany on the 25. of April and made a 4 hours travel back to Denmark.
Romme knows the landscape and goes north and south on the east side of its home range.
Romme does not fly to the nest area or into the territory where it was raised.

It is close to the nest. But that is it. Romme knows its surroundings well now.

'Romme' and the nest
Written by Ole Friis Larsen on 21 May 2022 at 17.06
Coloring rings and GPS transmitters on Sea Eagles show that the young eagles can roam far and wide and return to the nesting area where they grew up, but it is probably more about food than about trips home to the 'family'.
The American Cornell University, which is responsible for very serious research in birds, writes in an article that only a few species of very social birds - for example crows and cranes - can recognize each other after a year of separation.
The adult / adult Sea Eagles form pairs for life and can of course easily recognize each other, but they also see each other daily throughout the year.
'Romme' can probably easily recognize the area he grew up in and has learned to fly in, but he hardly thinks of the nest as his 'childhood home' if he sees it again.
There are examples of young eagles being allowed to visit nests with chicks, and we once assumed that it was probably earlier chicks from the nest, but just reading the color rings has shown that it can also be a complete stranger. young eagle that has nothing to do with either the nest or the adult / adult birds on the nest.
The parent birds can thus probably not distinguish between their own and others' young after a while.
It is common for larger birds such as geese and cranes to stay together in family flocks throughout the winter, but when the parent birds are about to breed again, last year's young are thrown out, and in most of the species the birds will not be able to recognize each other after a while. as a family, but only as fellow species.
'Romme' and his parents will therefore probably now just experience each other as other individuals of the same species.
