This is the rarely photographed female of the Diard's trogon. The male differs from the female in having scarlet on the belly and underbelly, black on the head and upper chest, a purplish-blue orbital ring, and reddish-brown on the back of the head. What stands out is a bright pink neck collar. The species grows to about 34 cm in length and feeds on ficus fruits and a variety of insects, including caterpillars, beetles, walking sticks (Phasmida), and grasshoppers.
