Lovebirds are a small, stocky variety of parrot, generally growing to be 5-7″, with a large beak. They usually live up to 10-12 years, but have been recorded to live as long as 25 years on occasion. Lovebirds are best kept in pairs, as they are very social and affectionate. If only raising one lovebird, you must be available to give it plenty of attention.
Habitat
A cage of a minimum of 32″ x 20″ x 20″ per pair of birds is recommended, with several perches or branches and dishes for food, drinking water, and bathing water. It is also recommended to have at least one nesting box placed high up in the cage. Lovebirds often like to hide away when feeling threatened and need a safe place to retreat.
Diet
A diet of primarily seeds provides great variety, but lacks some essential nutrients and should be supplemented with fruits, vegetables and greens, nuts, and even oyster shell or cuttlebone to supplement calcium. They especially love apples, broccoli, cabbage, kale, carrots, parsley, and spinach. Lovebirds also drink a lot of water, and vitamins can be added to their water as well.
