Lovebirds are smaller versions of parrots.
They don't mimic words as well as parrots do. They possess green bodies but have differently colored heads. Lovebirds were named because a pair of the resemble lovers sitting together preening each other. These birds are peculiar as they are loving only to their respective partners and don't extend love to others of their own kind. Lovebirds are small enough to fit into a standard size cage of 36 by 20 by 20 inches.
