An unhappy bird may begin to pluck its feathers or start screaming constantly for attention. Unless you have the time to devote to one of the more demanding breeds, pass on these lovely birds. You owe it to yourself and to the bird to be sure you are making the right choice. These beauties can, and will, be quite vocal at times. Some of the smaller birds, such as cockatiels, love birds, some of the smaller conures, or parakeets and canaries make wonderful apartment birds.
Some pets are able to interact peacefully with each other with no problems.
But it is a fact that some alpha' pets are quite jealous and will seek to harm the newcomer. Unless the bird will be in a room with a door than can be closed to prevent the other animals from getting too close, always make sure you are there to keep an eye on things. All it takes is one swipe from the cat's claws or one bite from your dog and your new bird could be killed. Birds don't just live on seeds alone. They require fresh fruits and vegetables, the occasional snack of people food', and lots of fresh water.
