An important
quality of Forpus Parrotlets is that they are sexually
dimorphic. This means that the sex of the bird can be determined by
visual observation which makes pairing birds easy and does not require
surgical or genetic sexing. In all but one of the species within the
Forpus genus, the males have a varying amount of vivid or deep blue
on their rumps. The males of all species have shades of vivid blue
on primary and secondary feathers on their wings. The females are similar
in appearance but always lack the blue markings on the wings. Even
young chicks can be sexed by their coloration, another bonus when deciding
which offspring to hold back for future breeders. The only species
in which the female has blue on the wing are the Yellow Face, and even
then, the blue is of a much paler shade.
