Feeding

The yellow-billed prefers shallow water where if feeds on small fish, amphibians, molluscs, crustacea, insects and occasionally small mammals.

Breeding

Wildfile Specials

• Yellow-billed storks engage in "Swaying-Twig Grasping": part of the mating display involves the male standing on a  potential nest and gently picking up twigs and releasing them while swaying its head from side to side.
• Yellow-biiled storks excrete urine onto their legs in order to cool down.  They also regurgitate water for their chicks so they can  keep cool.
• Parents sometimes help to keep their chicks  cool by spreading their wings to provide shade.
