At first glance, one can think that this is a horror scene where a flamingo opened the skull of another flamingo with its beak. But do not worry, these are just two parents feeding their baby. Flamingos produce milk similar to that of pigeons. Derived from the glands in the upper digestive tract and may also be produced by the male flamingo. Milk contains fat, proteins and blood cells (red and white) and has an intense red color, that looks like blood. Here a parent feeds his baby with milk coming out of his mouth, while the second puts milk on the head of the first, so it can also reach the mouth of the baby.
