Geographic Range and Habitat
Cockatiels are native to Australia and can be found in Tasmania. They prefer to be inland near fresh bodies of water. These birds are nomadic and follow predictable migratory patterns in Australia. For their nesting sites, cockatiels prefer to be near bodies of water and large hollow trees.
Physical Descriptions
Cockatiels are slender and streamline. They are also the only crested parrot that has their tail come into a point. The tail makes up half of their body length; moreover, the tail fans out to help it control altitude and balance during flight. Male and female cockatiels are very similar in appearance. They both have dark brown irises and a crest about 5 cm made of a dozen of feathers. Their crests would raise at different angles to indicate their mood and is also a form of communication. The underside of their tail had alternating patterns of color. Males and females can be differentiated through the coloring of their feathers. Males have a dark brown to a gray plumage with bright orange circular patterns on its cheeks bordered by white. On the other hand, females have duller orange circular cheeks without a white border and mainly gray plumage. Cockatiels' beaks and toes are alike those of parrots; their upper beaks are curved to a point and they are zygodactyly (meaning they have two toes pointing backward and two toes pointing forward).
Reproduction
Cockatiels mate with only one partner in their lifetime; they start mating early on. Their bond is for not only for reproduction, they also stay together loyally after mating. They male and female would show several ritualistic behaviors before they mate. An example would be the females making small peeps and having their tails stand erect to show readiness while the male would pound their beaks to attract attention and strut-walk. The male would also inspect the nest to see it is safe or not before letting the female enter. The cockatiels' mating season is usually when there is much rainfall for the abundant supply of food. A pair usually claims the entire tree as their nest. If any of their eggs break, females can lay more since they are indeterminate egg-layers. The male and female takes turns sitting on the eggs, usually the male in the morning and the female at night. While the female is in the nest keeping the eggs warm, the males stand guard outside. After the babies hatch, they are fed by the parents, usually the male cockatiel. Moreover, cockatiels do not abandon their babies.
Food Habits
Cockatiels are ground foragers. They eat seeds, soft fruits, some plants, small insects, and animal matter. They drink very little water from water holes and small pools because they are vulnerable on the ground. Cockatiels do not need much water since they function with metabolic water production.
As a Pet
Cockatiels are the second most popular type of bird to be kept as pets. They are loyal to their owners once they establish a bond similar to the bond with their mate. These birds are also popular as pets since they show affection by letting the owner pet or stroke its head. Also, males are able to whistle tunes they have heard making them more popular as pets.
