As the name suggests, this is the largest species of flamingos. Standing up, it is only slightly shorter than a human being, length reaching up to 150 cms. Its light pink plumage and red wing-coverts come from carotenoids, a group of substances that birds take in through small crustaceans. If they do not have access to these, they will not develop the pink color. Therefore, sites with these conditions extra popular, such as this one at Lake Manyara with the largest concentration of flamingos that I've seen so far. As part of the flock moves on the red wings almost transform the sky into glowing night sky in the middle of the day.
