You can hear the sound they make flying at 2:22 from ages away. A birds that evolved with pretty much no predators except maybe a giant eagle, which would see them before it hears them, had no reason to be quiet.
Every pigeon makes this kind of noise with their flight feathers, as they are gregarious birds, it's a way of warning their fellow pigeons when there is a predator around.
I love Kererus they are so cute 🥰. In my garden I have wood pigeon (ramiers) wich really look like little Kererus... they are bigger than the normal grey pigeons and so cute 🥰
