Greater flamingos (Phœnicopterus roseus) are sociable and particularly expressive birds that quack with sounds reminiscent of those of geese. While their typical flight call is loud and repeated, they produce a softer, continuous babbling on land when feeding and nasal growls during parades and mating rituals. Greater flamingos have a strong voice from the beginning of their life, and a real hubbub reigns in the colonies.
