A variant of Pacific parrotlet (Forpus coelestis)

Representative Pacific parrotletphoto — a dedicated image of this exact morph isn't available yet.
The wild-type Pacific (Celestial) parrotlet: a stocky little green bird, cocks showing cobalt-blue streaking behind the eye and on the wing/rump, hens lacking the blue. The base for all the trade mutations.
Keeper tips for this variant
Despite the sparrow size these are bold and bitey — house one per cage or a bonded pair, as parrotlets will badly injure cagemates in disputes.
