Unlike the other species, they will only produce one clutch a year and sometimes one clutch every other year. Unfortunately, they also tend to be much more susceptible to stress than other parrotlets. Spectacled Parrotlets Spectacled parrotlets are at the small end of the scale weighing around 25 grams and less than five inches in length. Males are a deep, rich evergreen with a bright blue eye ring, cobalt rump, primary and secondary coverts, secondaries and under wing coverts, bright violet blue on the primaries and rump. Both males and females have horn-colored beaks and legs.
Spectacles are the only parrotlets with a true eye ring.
Fortunately, they are also quite prolific and relatively easy to breed so their numbers have increased dramatically. The rarest and largest species is the Yellow Face parrotlet weighing 50 grams and almost six inches in length. The males have deep violet blue primaries and secondaries similar to male Pacifics including the blue eye streak. Females also have blue rumps which is lighter than the males. As the name implies, both males and females have bright yellow faces.
