Female Red-tailed Cockatoo tail feather carved into the likeness of a Phoenix
The family name for Flamingoes is Phoenicopterae, from the word phoenix.
It makes sense in a way because these birds live in fire, sort of. They inhabit environments that are too extreme for any other bird or mammal. They gather and breed in super salty and alkaline environments that would quickly kill other creatures. They can drink very hot water, close to boiling. As Katrina von Gruow writes in The Unfeathered Bird, “Flamingoes are really very special birds indeed and, with their carmine wings, emerging from the intense chemical heat of the tropical salt lakes, certainly worthy of the name “phoenix".”
