Cuckoo - The Enemy in My Nest - Most cuckoos are less radical than our local variety that throw out the eggs of the foster parents. They just add an egg to the nest and let their young be fostered. Is that a phenomenal trick or one of the mysteries of evolution? Cuckoo - The Enemy in My Nest (2017) Director: Volker Arzt, Dietmar Nill Writers: Volker Arzt, Angelika Sigl Narrator: Dan Wesker Genre: Documentary Language: English Synopsis: It’s no news that cuckoos are brood parasites: they lay their eggs into the nests of other bird species – a clever trick that spares the rearing and feeding of own offspring. We’ve all heard the story. But why do other parent birds let this happen? Are they too stupid? Too inept? Or simply clueless? Admittedly, cuckoo’s eggs do usually look deceptively genuine. But the cuckoo chick? Not even remotely! It quickly grows into a giant that looks nothing like its new family. So why don’t the adoptive parents notice the sham then? Some cuckoo chicks even go as far as to kill the other chicks in the nest. In most cases, however, they just smuggle their eggs into the nests of other birds, some of which are intelligent enough to spot this easily. Still, they don’t throw the egg out. Until recently, the ornithologists’ theory was: the “victims” have yet to learn to counteract. Turns out: they may even profit from having strangers’ chicks in their nest! So is cuckoo’s behavior a phenomenal trick or an evolutionary riddle? ···················································································· SUPPORT US! ✘ Membership - https://bit.ly/3pYmbNb MORE MOVIES! ► Ocean Life: https://bit.ly/425KqWy ► Nature & Animals: https://bit.ly/4223SDL ► All Playlists: https://bit.ly/3MvVwyi #animals #wildlife #oceans ···················································································· COPYRIGHT: All of the films published by us are legally licensed.
