It has occurred in Macau so it must be traded! I cannot believe that a Turdoides babbler flew from Burma to Macau. The occurence of such an inlikely species in apprarently good condition is the reason why I am very cautious about ascribing wild origin to commonly traded birds from a similar geographic region - such as Blue-throated Flycatcher, see my post on that species in TPK earlier today.
