From ANIMA
From running the Greek through a few translations, it sounds like these are the babies of unreleasable Eagle Owls. But the babies will get to go free after they have been properly raised by their parents, just as in the wild!
Greek Text
Για τον μήνα τον καλό σας έχουμε μπουφάκια ολόφρεσκα νέας εσοδείας (δικιάς μας), από μη απελευθερώσιμους γονείς στο Κέντρο Περίθαλψης, στα Καλύβια. Όπως και τα περσινά και τα προπέρσινα όταν έλθει η ώρα θα τοποθετηθούν σε κλωβό σταδιακής επανένταξης και θα αποδοθούν στη φύση.
Also a pair of unreleasable Barn Owls, with their babies, and a helpful uncle in the background as well!
Greek text
Και άλλη εγχώρια παραγωγή, τυτουδάκια στα Καλύβια, εδώ βοηθάει και ο θείος το ζευγάρι, όπως φαίνεται…
I believe the Eagle Owls are 2 parents, and 2 babies. Male owls can be up to around 20% smaller than females.
Oh… My antropocentrism lead me to imagine the big one as the male. But it is true that many animals have a bigger female.
Even though she is bigger, you still don’t tell her that to her face anyway! 😇
