   Plumage

   Overall feather coloration and pattern.

   Adult males have a brilliant orange patch on the nape, extending slightly onto the hindcrown. The head, neck, and breast are pale grey, transitioning to a greenish-yellow belly. The back and wings are bright green, with a distinct yellow band on the undertail coverts. The tail is green with a broad yellow terminal band. Adult females are generally duller, with a less extensive and paler orange nape patch, often appearing more yellowish-orange, and a more greenish-grey head and breast. Juveniles are predominantly green, lacking the distinct orange nape and grey head of adults, with some yellowish mottling on the underparts.

   No significant seasonal plumage changes are reported for this species.

   Sexual dimorphism

Key field marks

• Orange Nape Patch. Look for the bright orange patch on the back of the neck, especially prominent in males. In females, it's duller and smaller, often yellowish-orange.
• Head and Breast Color. Observe the pale grey head and breast in males, contrasting with the green body. Females have a more greenish-grey wash.
• Overall Green Plumage. The rest of the body is bright green, providing excellent camouflage in the canopy.
• Yellow Undertail Coverts and Tail Band. Note the bright yellow undertail coverts and a distinct yellow terminal band on the green tail, visible when the bird is perched or in flight.
• Vocalization. Listen for its characteristic soft, mournful 'hoo-hoo-hoo' cooing, which can help locate the bird even when it's hidden by foliage.
