Life Sciences Paper 1, November 2024, question 3.1.1(b)

Flamingos are long-legged wading birds that feed on tiny organisms filtered from shallow lakes. A female flamingo lays one egg at a time. Both parents take turns to sit on the egg and keep it warm until it hatches, which takes about 28 days. The parents guard the nest against predators during this time. After hatching, both parents feed the chick with a special milk-like secretion from their throats until it is able to feed itself.
