The parrotlet parrot might be small in size but it is big in personality. These pint-size parrots are bold and assertive, and they can learn to talk, too. Parrotlets may look like little green parakeets, but they are not priced like parakeets, nor do they share the same temperament. At 5 inches in length, they are also a couple of inches smaller than parakeets. There are several species of parrotlet, but only two are commonly found in the pet trade, the Pacific parrotlet (Forpus coelestis) and the green-rumped parrotlet (Forpus passerinus), though most of the others are available if you inquire from breeders. The Pacific Parrotlet (Forpus coelestis) has become one of the more popular small birds in the country, and is the most common of the various parrotlet species.
