Male Hispaniolan Trogon.
Possible Juvenile Male Hispaniolan Trogon.

Note the dull iris and fresh rounded juvenile rectrices, the central feathers with an indistinct and rounded terminal band. The indistinctly barred tertials and wing coverts, and the moderately barred pattern to the outer webs of the primaries may indicate juvenile feathers in a male, in which case the juvenile secondaries also can have very indistinct barring (versus completely unbarred in females). but more study is needed to confirm sexing criteria in juveniles of this species.

Formative Female Hispaniolan Trogon.

The juvenile central rectrices are worn, rounded at the tips, and with a smaller and more rounded subterminal band than found in basic central rectrices. Note also that the upperwing secondary coverts and inner two tertials appear to be replaced, fresher, blacker, and contrasting with the more worn and browner secondaries. the outer primaries appear tapered at the tips and tinged brownish, but show mpre distinct bars to the outer web than found in some juvenile females. Note also the duller brownish-red iris, typical of first-year birds. Formative Plumage with retained juvenile remiges, but the rectrices are broad, truncate, and with a wide dark terminal band, unlike juvenile feathers. It may be possible that central and other rectrices can be replaced during the Preformative Molt in some birds; study is needed. The complete lack of barring to the upperwing coverts and secondaries indicate a female.

Formative Hispaniolan Trogon, possible Male.

The best way to identify Formative Plumage is by the retained juvenile middle rectrices (r3-r5), which are narrow and rounded at the tips (as opposed to truncate and squared), relatively more worn, and from below show longer and more ovate white spots with a transverse border and a dusky bar which is narrower than in basic rectrices. Iris color appears to change from reddish-brown to brownish red during the first year. The outer webs to the primaries appear moderately barred, suggesting juvenile feathers on a male, but more study is needed on this.

Definitive Basic Female Hispaniolan Trogon.

In basic plumage, females differ from males in having unmarked green and dusky upperwing coverts and grayish to dusky secondaries, without bold black-and-white barring. The broad and truncate central rectrices with wide metallic-blue terminal band and the dusky and truncate outer primaries indicate Definitive Basic Plumage, as does the bright red iris. Note also the sparse and moderately indistinct barring to the outer webs of the primaries; definitive basic males have bolder black-and-white barring here.

Definitive Basic Female Hispaniolan Trogon.

The broad and truncate middle rectrices from below show a sharp and horizontal border with the dark subterminal band, indicate basic feathers and Definitive Basic Plumage. The unbarred wing coverts and secondaries, along with the lack of distinct barring to the outer webs of the basic primaries indicate a female.

Definitive Basic Female Hispaniolan Trogon.

Note the unmarked wing feathers and rather indistinct dark barring to the outer webs of the primaries. The darker middle than outer secondaries reflects a molt cline based on convergent replacement within this tract, and indicates Definitive Basic Plumage.

Definitive Basic Male Hispaniolan Trogon.

Males and females are similar in plumage except for the bold black-and-white barring to the secondary coverts, primary coverts, and secondaries. The outer webs to the primaries are also more boldly barred in males. The squared rectrices, broad square band to the tip of the central rectrix, and black primaries indicate Definitive Basic Plumage. Iris color in adults is bright orange-red to red.

Definitive Basic Male Hispaniolan Trogon.

The basic middle rectrices (r3–r5) below are broad, truncate, often flared at the tip, and show a broad squared white tip including a horizontal border with the metallic-blue subterminal band. The bold black-and-white barring to the outer web of the primaries indicates a male.

Definitive Basic Male Hispaniolan Trogon.

The boldly barred wing coverts and secondaries indicate a male, and the broad, truncate, and flared rectrices indicate Definitive Basic Plumage. The broad terminal band to the outer inner web of the central also indicates a basic feather.

Adult Female Hispaniolan Trogon.

In both sexes of juveniles and adults the bill is bright yellow tinged orange. In adults, the iris varies from pale orange to deep bright red. It may be possible that both bill and iris color becomes more vivid during pre-breeding and breeding periods (perhaps January–June) than during molting and non breeding periods (perhaps August–December).

Adult Male Hispaniolan Trogon.

The bill of trogons is short and stout with a decurved culmen, and has a slight "tooth" along the cutting edge of the upper mandible as is often found in fruit-eating birds. The iris in adults is bright pale orange to red, and the small legs and feet are usually brownish to brownish gray, with black claws.
