Greater Sulphur-crested Cockatoo
Cacatua galerita
This large white cockatoo has a long forward-curving yellow crest, yellow on the underwing linings and in the base of the tail. Sometimes, the feathers of the cheeks are yellowish. Its beak is black. In the male, the eye is solid black and in the female it is brownish red.
What They Eat
Sulphur-crested Cockatoos eat seeds, fruits, berries,
nuts, flowers, leaf buds and insect matter. They also plague farmers
by eating newly sprouted seeds and raiding crops as they ripen.
They may also help themselves to bagged grain. They also eat the
seeds of many weed species but their damage to crops outweighs
their benefit at controlling weeds.
Where They Live
This species is common in a
wide variety of wooded and savannah habitats in New Guinea, northern
and eastern Australia, and Tasmania usually near water.
What They Do
During the breeding season, Sulphur-crested
Cockatoos seem to congregate in pairs or small groups. At other
times they associate in large flocks of hundreds of birds. In
flight, these beautiful white parrots show yellow underwing linings
and often screech loudly. They often feed on the ground and employ
a reliable sentinel system to warn feeding birds of approaching
danger. Birds perched on the periphery of the foraging flock will
scream and take flight, the rest of the flock rising to escape
with them. When relaxed the feathers of the
cheeks are extended to cover the lower mandible.
How They’re Doing
This is an extremely common bird that
is regarded as an agricultural pest because of the heavy toll
flocks take on agricultural fruit and cereal crops. Losses of
between 50-90% of peas, safflower, maize and sunflower along with
the continued growth of bird populations has left farmers in a
difficult position and has led to the slaughter of thousands of
birds by poisoning, trapping, clubbing and shooting.
