Males have dark cobalt wings, backs, rumps and streak behind the eye. Females are various shades of green with no blue and an emerald green eyestreak. Males of this subspecies have silver gray backs and wings as well an eyestreak that completely encircles the back of the head. There are several color mutations of Pacific parrotlets now available although they are very expensive compared to normal green birds. All of these mutations have proved to be recessive and none are sex-linked, including the lutinos.
Pacifics have a well-deserved reputation for being feisty and bold.
They are the most fearless of the parrotlets and can be very stubborn and strong-willed at times. As with all parrots, they need to be taught limits and realize who is the boss. It is interesting to note that the blue mutation seems to have a much calmer, steadier disposition both as a pet and with each other. Despite the Pacific's feisty personality, they make wonderful pets. They are always so curious and there is never a dull moment.
