Beware - Very LOUD! Nursery of birds of prey. Falcons, snowy owls, Yoll's parents, and a kind wolf

Another video from the nursery "Peregrine Falcon", which is located in the suburbs of Moscow. I went there for dozens of kilograms of mice and went to see the birds since I was already there.
The screaming birds at the beginning of the video are young falcons, hybrids of a saker falcon with a gyrfalcon. They are screaming with no particular reason - simply because they like it and want attention. They have fluff on their heads. When they grow old, they will scream less.
Snowy owls are already hatching the second clutch of eggs. Chicks from the first were hatched in an incubator. We checked the quality of eggs and it turned out that only 2 out of 6 were good and the other 4 were bad, with no chicks inside. I specifically decided to show you a piece of video where we shone the phone torch through the eggs to see the development of embryos. I took the bad eggs to myself, so that I could transfer them to someone who collect bird eggs.
Yoll's parents raised 8 chicks this year. They have already left the nest.
A good polar wolf can lick a person to death.
