ho trovato delle news sul nido ... se non capisco male la coppia nidificante non e' quella dello scorso anno... nel tread si parla anche di un nido di gufo purtroppo finito male a inizio giusgno. Posto anche quella parte di messaggio che mi e' sembrata interessante
NEWS FROM THE NEST
June 21, 2007 At the Eagle’s Nest
Our newest family friends are still without names; everything seems to be well at the nest site.
Unfortunately, the location of our camera ended up being right by the eagles’ toilet, hence the previously foggy picture, before we went and cleaned up the lens. This nest is a so called “crown nest”, located at the very top of the tree, and sheltered by numerous branches. There simply are not many choices where to install the camera.
We have received a few questions about the June 20th picture, at 09.16 hours. It is a unique picture of the parent bird bringing prey, this time a young fox, to the nest.
The fact that the female eagle seems to be spending a lot of time with her young one probably means that there is adequate food available. At the eagles’ nest, the birds only eat what they need, and no food is wasted. Additionally, the pair has kept their nest in an excellent condition, and they continue to fix it up as needed with fresh boughs.
Heikki and I think that the nestling is a male, but we will be getting more information soon from Kalevi Tunturi based on the results of his measurements of the young one.
A good and peaceful Midsummer Day to all of our readers from all of us at the Flight of the Eagle Society (Kotkan Lento ry).

June 6, 2007. Nesting of the Great Grey Owl Has Failed.
The nesting of the Great Grey Owl has failed. Everything was well on June 5th at 21.10 hours. The female owl had left the nest to go hunting for food. An hour later one of the owlets had disappeared, and the other one was dead inside the nest. Soon after, the female brings a gopher and leaves it in the nest. The owl spends the following night next to its young one, then admits defeat, and leaves the nest.
What caused the nesting to fail? The culprit was probably a small mammalian predator, or a bird of prey. I am guessing it was a mammalian predator that the loud nestlings begging for food unwittingly lead to the unprotected nest. Would a bird of prey have killed the other owlet? A large predator, such as a chicken hawk, would have taken both nestlings. We cannot completely rule out the owlets dying for lack of food, but if that was the case, then where did the other owlet go?
Why did the female owl not protect the nest? I believe the cause for that is simply the need for more food. When the nestlings beg for food increasingly, and the male does not bring in enough, the female will leave the young ones to go hunting. The way I see it, the female should have stayed at the nest continuously while the owlets were as young as they were. I noticed the absences of the female earlier, and mentioned them in my answers to viewers’ questions.
There is another Great Grey Owl nest perched on a snag just a couple hundred yards away from the online nest. It is quite possible that the same male in his spring fever enticed two females to nest while gophers were running around in abundance. But once there were fewer gophers, it was no longer possible to feed young ones in two nests. In any case, we have seen the second nest’s male only a couple times in the pictures.
While birds of prey hunt, they leave many young animals orphaned. At the same time, their young ones do not live in complete safety either. Life is tough in the wild. We have just witnessed one of its lessons.
Kalevi Tunturi.
