The last days before - and the hatch - here the proces:
RRP
SO WHAT HAPPENS RIGHT BEFORE HATCH? JUST A FEW DAYS FROM EXTERNAL PIP, THE RAPIDLY GROWING EMBRYO IS TAKING UP NEARLY ALL THE SPACE IN THE EGG.ABOUT 4 DAYS BEFORE HATCHING THE CHICK DEVELOPS AN EGG TOOTH AT THE TOP OF ITS BILL.
IT...
Turns so that its head is at the large end of the egg next to the air space.
Pierces the internal membrane - the internal pip - and begins to breathe air with its lungs. Hatch has started!
Takes the yolk sac into its body as it consumes most of the remaining albumen and yolk.
Grows enough to contract the hatching muscle, pointing its head up and positioning its egg tooth against the shell of the egg. The eggshell is thinner and weaker than when it was laid, since the growing embryo absorbed calcium from the shell for its bones.
Rubs its egg tooth against the shell, which cuts a small hole. We have an external pip!
Rotates its body, slowly cutting a ring around the shell.
Pushes its body against the shell, forcing the shell apart.
Works itself free of the shell membranes and halves. The eaglet has landed and hatch is complete!
Within a few hours the egg tooth dries up and falls off

Eggshells and darkness
Posted by Ole Friis Larsen on March 30, 2020 at 07:55
The eggshells can disappear into the grass in the nesting bowl, but they can also be eaten by the eagles as calcium pill, or they can be thrown out while cleaning the nest.

The eagles are around the clock and undoubtedly get a good night vision. I don't know if there are studies on it, but darkness is also experienced differently by us humans. If we go from the light inside a house into the darkness, we can see nothing. If we stay out in the dark, the eyes will get used to the dim light in half an hour and we can see more or less well.

In Israel, there are webcams on, among other things, a nest with Snake eagles [EDIT: I don't find translation for the Danish word Ørnevåge] and a nest with eagle watch (a large species of wakefulness). Both nests have occasionally been attacked at night by the Great Horned Owl, and it has been possible to see the adult / adult birds on the nests reacting before the owl appeared. Owls are very silent in flight, so the parent birds of the nests must be able to see it in the dark, since they can now threaten threateningly with wide wings in the right direction before the attack

Acc. to the Danish data base for birdsobservations, 4 young eagles at least are in the area. But at the moment they leave the nest in peace. https://dofbasen.dk/popobs.php?obs=obs&obsid=24371366
Here is Oles comment on the web site in GT:
Young eagles are rejected
Posted by Ole Friis Larsen on April 1, 2020 at 8.18

I was in the Saksfjed-Shelf Hook area yesterday - Tuesday, March 31 - to watch birds at all. It is an excellent location for migratory birds along the coast to the east into the Baltic and inland from the south right now.

On that occasion, I saw at one point four young sea eagles in the air over the bay near the eagle nest. Here they were kept at a distance by one of the eagles from the breeding pair - probably the male - who simply circled around the beach next to the nest and 'showed the flag'. It was enough for the young to stay a little distance and forge / hunt ducks and geese on the water elsewhere across the bay. Therefore, when one cannot see one of the eagles at the nest, it may, among other things, be in the process of marking that access here is prohibited for other eagles.

APR. 2.

Now there is very little food left for cattle and horse in the reserve. That is on purpose. Flower plants will be in favour during spring and summer in stead of grass. The ponyes will now supply food from bushes and trees. A woodden savannah landscape is going to be. Rewilding by great herbivores.

Yesterdays prey in the nest was not a duck without feathers, but the rest of a hare or a fox, thr experts around the nest tell.


THIS morning there was a shift aroung 06.15 and at 07.30 the male starts calling evry15-20 sec.

08.15 F comes back, while M still calls. I do not know why M called.

The video: https://www.facebook.com/havoernene/vid ... 986836033/

08.17 M leaves the eggs and flies out. Then silence came back.

We do not know which egg has broken, so today there is either 2 or 5 days to first hatch.
