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. Voice: The cinnamon-rumped trogon has a short, sharp cry that is normally repeated 4–5 times during a call. This repeated cry is phonetically approximated as "ta-y-aup-ta-y-aup". There is normally a pause of about 10–15 seconds between these calls. They additionally have a second "purring" call. These different vocalizations may be used in different scenarios, though this has not been confirmed.
