Sulphur-crested Cockatoo

Description:

The Sulphur-crested Cockatoo, Cacatua galerita, is a relatively large white cockatoo found in wooded habitats in Australia and New Guinea. They can be locally very numerous, leading to them sometimes being considered pests. Their distinctive raucous call can be very loud; it is adapted to travel through the forest environments in which they live, including tropical and subtropical rainforests. These birds are naturally curious, as well as very intelligent. They have adapted very well to European settlement in Australia and live in many urban areas. These birds are well known for their forward-curving sulphur crests which can be used to show off their moods. They are very long-lived, and can live upwards of 70 years in captivity,[citation needed] although they only live to about 20–40 years in the wild. They have been known to engage in geophagy, the process of eating clay to detoxify their food. These birds produce a very fine powder to waterproof themselves instead of oil as many other creatures do.

Habitat:

They inhabit a wide area of Australia along the coastal regions from North to East to South and can withstand a wide range of climate conditions.

Notes:

Species that feed on the ground are very vulnerable to predator attack. The Cockatoo has evolved a behavioural adaptation to protect against this: whenever there is a flock on the ground, there is at least one high up in a tree (usually a dead tree), keeping guard. This is so well-known that it has even entered Australian slang: a person keeping guard for sudden police raids on illegal gambling gatherings is referred to as a Cockatoo or Cocky for short.
