Parrotlets are the smallest parrot species commonly bred in captivity. The genus Forpus, particularly the celestial or Pacific parrotlet, is growing in availability and popularity in aviculture due to its size. It has a stocky build and a short tail. In the wild, most parrotlet species travel in flocks of about five to forty but the number could be as large as one hundred. They form lifelong, tight pair bonds with their chosen mates. If left alone for too long, a single parrotlet can lose some of its companion ability.
The Pacific parrotlet, in particular, has little trouble challenging other animals and humans. Parrotlets in general are feisty, affectionate and willful. If someone wants a great companion, they should keep only a single bird, because a pair of parrotlets will probably bond closely to each other to the exclusion of the owner. Parrotlets are dimorphic and easy to pair up, and they do enjoy each otherís company. They can also be kept peaceably in groups in large aviaries, but itís best to keep them separate from other species.
