streaks around the neck and on the back. When it is perched, a small amount of black can be seen in its wings; these are the “flight feathers.” They have bright red skin around their eyes, which in adults are yellow. Their legs are brick red and their bills are bright yellow with a black tip. The James's flamingo is similar to most of the

species in South America, but the Chilean flamingo is pinker, with a longer bill (which is not yellow), and the Andean flamingo is larger, with more black in the wings and bill, and with yellow legs. The easiest way to distinguish James's flamingos is by their lighter-colored feathers and the bright yellow on their bills. A good method to distinguish the two ''Phoenicoparrus'' flamingo species from other flamingo species is to look at their feet. The two ''Phoenicoparrus'' species have three toes but no

When the birds are roosting, they face into the wind so that the rain will not blow upwards and soak the underside of their feathers.

schedule and the color of the new feathers depends on the nature of their diet. There is no difference in color between males and females.

Flight

All flamingo species are capable of flying. The flight feathers are easily distinguished in James's flamingos as they are the only black feathers on the bird. To begin flying, they run a few steps and then begin to flap their wings. When they want to land, they repeat this process in reverse, and as they touch down to a surface, they continue to run as they decelerate and stop flapping their wings. When migrating in a flock, flamingos have been observed to fly at speeds of up to . But they may not reach this speed when traveling shorter distances.

portion of the bill contains lamellae that are ridge-like with a curvature and distal end become more like hooks. Marginal and submarginal lamellae are found, and James's flamingo has the greatest number of both, which also means a smaller intermarginal distance is seen between them. About 21 lamellae per cm are found in this species, which is more than twice the number found in other flamingos. When the upper and lower jaws close together, the lamellae mesh together to allow the bill to be closed fully.Jenkin, P.M. "The Filter-Feeding and Food of Flamingoes (Phoenicopter)".
