What I am very sure of is the conclusion of Hayes 2006: "Because the two taxa may often have opportunity to interbreed on Tobago but tend to mate assortatively, they appear to have achieved essential reproductive isolation, thus supporting their current treatment as distinct species." (J. Carib. Ornithol. 19:12-20). One can of course disagree with this conclusion, but it seems that the SACC has followed this treatment without too many questions in reading their note 10 for B striata. The data in Hayes 2006 says that there were 50% of scored individuals that scored 7-8, 16% scored 1-3, while the rest were 34% scoring 4-6 (6% scored 5 which is the only certain hybrid category).
