The Different Species of CockatooĬockatoos consume a wide range of predominately vegetable food items such as tubers, roots, nuts, and fruits, with seeds forming a large part of their diet. In black cockatoos, for instance, it can take two years to complete, while in the long-billed Corella, it can be much shorter at around six months. Molting in this bird species is a complex and prolonged process. Interestingly enough, cockatoos also preen other birds’ feathers that are hard to get at. By doing so, they remove oil and dirt and realign feather barbs. To maintain their plumage, cockatoos frequently preen their feathers throughout the day. While in contrast, some female cockatoo species, such as the Galah and Major Mitchell’s cockatoo, the iris color presents as pink or red, or even brown-red in the white female cockatoo species. Male cockatoos are generally slightly larger than females and present with dark brown irises. In fact, cockatoos keep their large bills sharp by rasping the two jaws together when resting. Interestingly enough, cockatoo birds also use their strong bill as a third limb when climbing branches.Īnd it is this large bill aided by their muscular tongue which helps dehusk the seeds they are eating. This bird species is generally medium to large, of stocky build, has a length that ranges from 12 to 24 inches, and can weigh anything up to two and a half pounds.Ĭockatoos generally have long broad wings which can reach speeds up to 43 miles per hour which were recorded on Galah Cockatoo.īut having said that, larger cockatoo species such as Major Mitchell’s and the Sulpher-Crested cockatoos are also known to have rounder, shorter wings. In fact, cockatoos are visually different from parrots due to their lack of Dyck texture feathers.Īnd as a result, this bird species does not scatter light in such a way as to produce the vibrant blue and green colors often found in many parrots.Īs such, cockatoos have predominately white or black plumage with hints of yellow, pink, or red, and in some species, you find a brightly colored area of bare skin around the face and eye known as a peri ophthalmic ring.īut what truly sets the cockatoo apart is the adjustable feather crest on top of their head which they use to great effect to make themselves look bigger or when the bird is showing off. Yes, they have a waddling gait just like other parrots and share the same common traits such as a curved beak, short legs, strong claws with a zygodactyl foot, and the ability to fly, but that is where most of the similarities end.Ĭockatoos have a different arrangement of carotid arteries, a gall bladder, and even differences in their skull bones. Morphology of Cockatoosĭespite being classed as a part of the larger parrot family, the 21 species of cockatoo come with their own distinct features that set them apart from true parrots. And by the 18th century, cokato, cocatoo, and cocatore were also used in reference to this bird. Variants on the name during this time included crockadore, cacato, and cockatoo.
