According to avibase (http://avibase.bsc-eoc.org/species.jsp?avibaseid=CA694FB8F9B76A0B), the latest revision, probably 2009, still calls it Ramphastos swainsonii. In Clements 6th edition (version 6.7 incl. 2012 revisions), it is changed to Ramphastos ambiguus swainsonii; but AVIBASE still recognize it as Ramphastos swainsonii. But checking at Wikipedia, genetic studies separates Ramphastos swainsonii and Ramphastos ambiguus, as different species. Based on the new descriptions, Ramphastos ambiguus seems more appropiate for this picture than Ramphastos swainsonii. It is not just a re-naming, but a whole new genetic specie. Thanks bayucca. Very helpful.
