Stocky green-and-red quetzal of lowland rainforest. Perches in the mid story of mature rainforest, where most common in upland (terra firme) areas and areas around water. Compared to trogons, is larger and chunkier, with a red bill and without a prominent eye ring. The green uppertail coverts are long, extending down the back side of the tail to just past the tail tip. Listen for its song, a repeated two note series of a breathy whistle followed by a soft note, “wheeew … tuck … wheeew … tuck …”.
