Slaty-tailed trogon, Costa Rica. The Slaty-tailed Trogon (*Trogon massena*) is a striking, medium-to-large trogon found in the humid lowland forests of Central America and northwestern South America, ranging from southern Mexico down to Ecuador. Males are particularly eye-catching, sporting a brilliant iridescent green head, back, and upper breast, which contrasts sharply with their vivid red belly and undertail. True to its name, the tail is notably slaty-gray on the underside, distinguishing it from similar species. The bill is a bright orange-red, adding yet another splash of color to an already vivid bird. Females are more subdued, with a gray head and breast replacing the male's green, though they retain the red belly. Like other trogons, it has a distinctive upright, rather sluggish posture and tends to perch quietly in the forest midstory, sallying out to snatch fruit or large insects. Its call is a series of low, cooing notes that carry through the dense forest understory. It is considered one of the most beautiful birds in its range and is a sought-after sighting for birdwatchers visiting tropical Central America.
