Comoro Cuckooshrike Coracina cucullata

A medium-sized bird with a gray back, a black hood, and pale underparts. There is an unusual and rare olive morph in which the head and back are olive-gray and the underparts greenish-buff. The juvenile is a drastically different-looking heavily streaked and spotted bird. Found locally in montane forest on the islands of Grand Comoro and Moheli. The most common vocalizations are a descending high-pitched series of soft whistles and a mild, chatty series of “chew” and “tew” notes. Within its small range, most similar to Grand Comoro and Moheli Bulbuls, but easily separated by the paler underparts and lack of an orange bill.
