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

Pair Bonding

Pair bonding is very strong, and flamingos may be monogamous. However, flamingos have been observed to mate with more than one partner.

Copulation

A female will most often initiate copulation by walking away from the group. A male follows close behind.

The female stops, lowers her head, and spreads her wings. This behavior is an invitation to the male to mount her.

Mating occurs in the water. The male jumps onto the female's back from behind, firmly planting his feet on her wing joints.

After mating, the male stands on the female's back, then jumps off over her head.
