Ornithologists currently count 10 pairs of breeding sea eagles on the Curonian Spit.
Ornithologist Saulis Skuja, head of the organization Let’s Help the Eagles, recalled that in 1988 there were only two pairs of these birds included in the Red Book in Lithuania: one in Curonian Spit and the other in the Čepkeliai reserve. Now its population has grown significantly. Both the modified approach to species conservation and the modified traditions of agricultural activity are believed to be.
Ornithologists from the organization dealing with the eagle population in Lithuania are also arriving at the Curonian Spit, where in addition to sea eagles, small eagles also breed.

In the spring, let’s help the eagles climb the treetops to control their nests. Later, the puppies are ringed, transmitters are installed, so that they can monitor their migration and behavioral peculiarities.
A pair of eagles – international
These days, ornithologists have received photos of the Curonian Spit taken by photographer Vytautas Knyna. The photographs revealed the story of a pair of sea eagles that breed here. The photographer captured these two adult birds, which had colored rings. After viewing the photos, the records can be read. The man was surrounded by the “Let’s Eagles” ornithologists themselves. The ring was placed on the leg in 2010, about 5 km from the current nest, for a chick that is not yet flying. Now the mature bird has returned to the nest to rotate in its native places.
Even more interesting was the story of the woman. It ringed in 2014 in Latvia, about 220 km from the current nest.
“As far as we can remember, this is the second pair of international eagles, as we say, in Lithuania. Two chicks were counted in their nest and ringed. Eagles are usually quite sedentary birds. As we record how they get to Western European countries. It generally migrates as it matures, ”said S.Skuja.
These birds are monogamous, forming permanent pairs as long as both members of the pair are alive. After one family member dies, the second finds another partner. Recent winters have been quite favorable for sea eagles: the temperate climate has allowed them to find enough food and endure the cold season. But even a decade ago, ornithologists had to care for these birds, and they continued to lose near fish or meat nests.
Socket – sturgeon
In the first days of summer, ornithologists observed the nests of sea eagles. He counted how many chicks were overfed. Adult juvenile prey was also examined. The parents mainly transported fish, juvenile waterfowl, and mammal remains to their nests.

At the Curonian Spit, sea eagles were found in the nests of sea eagles. However, the find surprised many in a nest: the remains of a spiny sturgeon were found.
In recent years, attempts have been made to reintroduce sturgeons into the Baltic Sea. The fish found in the nest had a marker. This marker revealed that the sturgeon in the nest was released into the Neris River in April and swam about 300 km before the eagle dived.
“The sturgeon is a deep-sea fish. An eagle could barely catch it in the floating water. The fish was probably weak or had already fallen. The eagle is a weasel that can feed and soul,” he said. 15 minutes interviewed ornithologist.
As sea eagles hatch, tourists may not be able to see them. However, in the second half of summer, when cubs learn to fly, eagles can be seen more often – near dunes or flying over water.
