![]() ![]() ![]() In the past four years, more than 100 cockies have been tagged and tracked across Sydney under a project called “ Wingtags”. In Sydney, they were found to be the fifth most common bird species, being sighted in 60 per cent of gardens. During the 20 years between 19, the number of sightings of Sulphur-crested Cockatoos in Brisbane gardens quadrupled, and their numbers had increased markedly. Like the Galah and several other seed-eating parrots, it has also adapted well to the urban environment. Since then, however, it has expanded its range and increased in numbers, mainly due to the clearing of forest, establishment of water tanks, and the cultivation of cereal crops. When a flock is feeding on the ground, at least one individual will be perched high in a tree acting as a lookout guard or “sentinel” ready to warn its flock mates of approaching danger, such as a dingo or farmer.īefore the arrival of European people, the Sulphur-crested Cockatoo was probably largely confined to open woodlands and forest edges in eastern and northern Australia. However their fondness for seed of many kinds has also brought them into sharp conflict with farmers growing crops, who regard the species as a pest due to its habit of eating ripening grain on wheat, corn, sunflower, sorghum and other cereal plants, as well as sprouting seed on the ground. Being a seed-eater in the main, it is easily kept in cages and aviaries stocked with a mixture of seeds. Famous for its ability to imitate the voices of humans with phrases such as “Hello Cocky”, as well as to perform acrobatic acts, the Sulphur-crested Cockatoo is a popular and much-loved pet in many households both in Australia and overseas. ![]()
