'' Although Koh Chang is only three miles from the 

 nearest part of the mainland, I was very much surprised to 

 find a Trogon present. With its shade-haunting proclivities 

 and Aveak powers of flight it is almost the last bird one 

 expects to meet with on an island." — C. B. K.

There is little doubt that these specimens represent a 

 perfectly distinct race of this widespread Trogon, which can 

 be recognised at a glance when the fresh skins are compared 

 with recent skins of the allied forms, though the differences 

 in tint are difficult to express in words.
