Areale e habitat

Ward's trogon ranges from Bhutan and Arunachal in North Eastern India and into northern and eastern Myanmar and southern China (in western Yunnan). A disjunct population was reported to be common in Fan Si Pan in Vietnam in 1939, but there are no modern records of that species there. The species is generally montane, usually occurring between 1,500–3,200 m (4,900–10,500 ft) but occasionally coming down as low as 300 m (980 ft). There is some evidence that it moves to lower altitudes in winter.<p>The preferred habitat of Ward's trogon is subtropical hill forest dominated by Quercus and Castanopis and temperate broadleaf evergreen forest. Within these forests it is found in the understory, undergrowth and within bamboo stands.<p>The species is not a common one, although it can be locally common in some locations. It was treated as vulnerable by the IUCN in the 1990s, but secure populations have been found in Bhutan, so it is presently listed as near-threatened.
