Cockatiels are known for their distinctive yellow heads and bright red cheek spots and these medium sized birds make lovable pets. They are very playful and love to climb, so a variety of swings, ladders and ropes in its cage should be provided.
In the wild, cockatiels live in large flocks and mate for life so ideally you should keep two cockatiels together.
Unfortunately, they do not tolerate being kept with smaller birds and can easily hurt budgies or canaries in a fight. They tame easily and can learn to talk and mimic tunes, although they can be fairly loud.
