What type of feet does a flamingo have?

Wading birds, such as herons, usually have three toes forward and one behind, all long to support them on soft surfaces. Flamingoes, however, have a very small first rear toe, with three toes forward, webbed for swimming, that are not so long as most wading birds. What we see as the foot is only the toes. What we see as the lower leg bone is really the foot fused into a single bone, with a prominent heel joint that looks to us like a knee that bends backwards. Bird toes are as different as bird species, and fit their lifestyle. Most birds have one toe behind and maybe above, with three forward. Some birds have two forward and two behind, some have a toe that can shift from front to back, a few birds have only three toes forward; the Ostrich has only two toes forward.
