Cats will eat your pet bird. This may be true with many cats but sometimes a cat and bird can become friends. It depends on your cat's personality. Many cats will have their instinctive hunting skills kick in and could easily harm or kill the bird.
If you are going to introduce your cat and bird, you need to do it slowly. It is usually best to introduce a cat to birds when he is a kitten. Then he can grow up knowing the birds.
But at the end of the day, your cat has its predatory instincts and you never know when it might unleash them.
