Size The greater flamingo is the tallest flamingo, standing 20 to 150 cm (47-59 in.) and weighing up to kg lbs.). Males reach full size between one-and-a-half and two years. Male flamingos are slightly larger than females

Breeding Seasons

Flamingo colonies may breed at different times of the year. Breeding success is based on synchronous nesting of a flamingo colony so that chicks of a colony hatch around the same time in any one year. Colonies very rarely nest more than once a year.

Breeding and nest building may depend on rainfall and its effect on food supply.

Courtship

Groups of flamingos perform ritualized stretching and preening when courting begins.

Males group together and often run with bills pointed toward the sky and necks held straight out.

Birds interested in one another call to each other frequently and in unison.
