Cinnamon-rumped Trogon

The cinnamon-rumped trogon is a close relative of the scarlet-rumped trogon, which also resides in the Malay peninsula and Indonesia. These two birds have similar appearances, but the cinnamon trogon is slightly larger, and the birds can be distinguished by the eponymous coloration of the plumage on their backs and tails. This species contains two subspecies, the nominal H. o. orrhophaeus of Thailand and Malaysia, and H. o. vidua of Indonesia. Both subspecies exhibit distinct sexual dimorphism. The nominal subspecies (H. o. orrhophaeus) ranges from 45 – 61g and it is about 25 cm in length. Males of the subspecies have a black hood, distinct blue bill, and a narrow head. Their backs and tail plumage are a pale brown (cinnamon), and the plumage under the tail is white, bordered by black. Males have pink underbellies, which can be used to differentiate them from females, along with the female's dark brown hood. Juvenile birds resemble females of the species. H. o. vidua appears quite similar, though females of the subspecies tend to exhibit darker coloration in their plumage.

The cinnamon-rumped trogon is found in Southeast Asia, specifically in Peninsular Malaysia, Thailand and Borneo. The species requires undisturbed forest habitat, though across its range, it may be found at highly variable elevations, from sea level on the Thai-Malay peninsula up to 1,500 meters on Borneo. Its habitat preference appears to be moist, tropical lowlands, though it also resides in piedmont areas of Borneo and Sumatra. The cinnamon-rumped trogon is non-migratory.

Cinnamon-rumped trogons have a diet that consists mostly of insects. They mostly enjoy cicadas and many phasmids, and will also sometimes eat stick and leaf insects. This species typically hunts alone, but has also been noted to sometimes forage in smaller groups.
