MALE: upperparts dull green; forehead, cheeks, and throat bright yellowish-green; underparts dull yellowish- green with slight greyish tinge on breast; periophthalmic region cobalt-blue; lower back, rump, carpal edge, primary and secondary-coverts, secondaries, under wing-coverts, and axillaries violet-blue, darker on rump; primaries green with violet-blue on bases of innermost feathers; upper tail-coverts green; undersides of flight feathers bluish-green; tail green above, dusky green below; bill horn-colored tinged with brown; iris dark greyish brown; legs brownish.
FEMALE: all blue markings replaced by green; upperparts brighter green than in male; lower back, rump, and periophthalmic region emerald green; underparts yellowish-green, duller on under wing-coverts.
IMMATURES: males have emerald-green periophthalmic region and yellowish-green under wing-coverts; green intermixed with blue on rump, lower back, and wing-coverts; females resemble adult female.
LENGTH: 12cm. (4¾")
SUBSPECIES:
- F. c. metae - MALE similar to conspicillatus, but underparts brighter and more yellowish-green; head brighter green, particularly on throat and cheeks which are more yellowish; bend of wing more yellowish; blue periophthalmic ring much reduced, being restricted mainly to a partial superciliary line. FEMALE very similar to conspicillatus, but general plumage slightly more yellowish.
- F. c. caucae - MALE like conspicillatus, but blue of lower back, rump, and upper and under wing-coverts paler, less violet; heavier, more robust bill. FEMALE like conspicillatus, but with heavier, more robust bill.

- The Atlas of Parrots, Dr. David Alderton (1991)
ALTERNATIVE NAMES: None.
SEXES: The cock has a yellowish green forehead, extending to the cheeks and throat. The underparts are slightly duller in coloration, with a bluish gray suffusion on the breast. The area encircling the eyes is cobalt-blue. The wings and upper back are dark green, with the lower back and rump being violet-blue, of a darker shade over the rump itself. The primary and secondary coverts are also violet-blue, as are the under wing coverts, axillaries and the carpal edge of the wing. The primaries are green, with violet-blue restricted to their bases, while the secondaries are entirely violet-blue. The lower surface of the flight feathers are bluish green. The upper tail coverts and the tail are green, with the tail feathers being of a more dusky shade on their lower surface. Beak pinkish white; legs pinkish; irides dark brown.
Hens are duller in terms of overall coloration, with the blue areas of the cock being green in this instance. Their upperparts are brighter, with the area around the eye being emerald-green, as is the lower back and rump. The underparts are more yellowish green.
YOUNG BIRDS: Immature cocks have no blue encircling the eyes, with this area being emerald-green, while their under wing coverts are yellowish green. They can still be recognized however, because of the greenish blue coloration on their lower back and rump, as well as over the wing coverts. Hens in contrast are similar in appearance to adults.
RECOGNIZED SUBSPECIES: Three. These are as follows:
- F. c. conspicillatus: Present in eastern Panama, being resident in the Bayano River valley, and ranging westwards virtually to the Canal Zone. Also occurs in northern Colombia, east of the Andes in Meta, Boyaca and the upper Magdalena Valley as far as about the line of latitude at 10°N.
- F. c. metae: Occurs on the eastern slopes of the Eastern Andes, being present in Boyaca, Cundinamarca and Meta in the central part of Colombia, ranging eastwards in the vicinity of the Meta River into western Venezuela. Cocks of this race have brighter, more yellowish green underparts. The throat and cheeks are also more yellowish, with the plumage of the head being a brighter shade of green. The area of blue plumage around the eye is significantly reduced in size, being confined mainly to the rear of the eye. The bend of the wing is also yellower than in the case of the nominate race.
- F. c. caucae: Found to the west of the Western Andes, in the upper Patia Valley and in the Dagua Valley, as well as in the middle and upper part of the Cauca Valley, being present in both Narino and Cauca, southwestern Colombia. Cocks in this case are similar to those of the nominate race, but can be distinguished, at least in some cases, by the depth of their blue coloration. This is paler and less violet in the vicinity of the upper back and rump in this race, as with both upper and under wing coverts. The beak is somewhat bigger as well. Hens appear identical to those of F. c. conspicillatus, except for this difference in the relative size of their beaks. Known as the Cauca Spectacled Parrotlet. (The race formerly described as F. c. pallescens, recognized from the vicinity of the upper Patia Valley, is now considered to be conspecific with this form, as set out here.)

MALE: green of a rather dull tone, brighter on the forehead, crown and cheeks; upper tail coverts also green; under parts tinged with greyish blue. Lower back, rump and most of the wings ultramarine blue, very dark on the rump. Surrounding the eye there is a distinctive ring of cobalt blue. Iris dark brown; beak whitish; legs and feet flesh colored.
FEMALE: the green color is generally brighter but there is no blue at all in the plumage.
IMMATURES: are a dull edition of the adults and young cocks can be identified by the dull blue on the wings, lower back and rump, although they lack the blue ring around the eyes.
SUBSPECIES:
- F. c. caucae - this race is larger than the nominate race, the wings and tail are longer, and the beak heavier. The blue is less purplish.
