One Greater Flamingo-chick in Zoo Basel is fed on crop milk.

Crop milk is a way of feeding from the crop of parent birds, by regurgitating to young birds. They are found among all pigeons and doves where they are referred to as pigeon milk. Crop milk is also produced by flamingos and some penguins.[1][2][3]
