[QUOTE="Rasmus Boegh, post: 1298945, member: 1146"] I'd strongly suggest splitting it into three (Venezuelan, Orange-backed & Campo). There is very strong evidence (morphology, vocal, behavior, and, most recently, sympatry [e.g. in Tocantins, Brazil, Orange-backed and Campo occur together w/o any evidence of interbreeding - same can be seen in Belém where both have been introduced]) that they should be split and this is a case where I'd be willing to guarantee that authorities that haven't split them yet will do so in their next update (at least if they keep even a bit update with the developements). I might suggest a small update to the OPUS rules; generally, follow the already established idea (follow the majority of the major check-lists), but not when we are aware of [i]strong published[/i] evidence that clearly shows the minority is right. The troupials are one such case. [/QUOTE]
