Are flamingos viviparous or oviparous?
They lay eggs and nest them until they hatch, which would make them oviparous. They build quite tall nests of mud and debris in shallow areas. Their coloring comes from the food they eat and can fade without the proper nutrients. Viviparous means that the eggs are retained inside the body where the young hatch and then leave through the cloaca opening, as it happens with some snake species.
