I just saw on Facebook that the ABA Checklist Committee has added Black-backed Oriole to the ABA Checklist.
This bird was in Pennsylvania from January to April 2017 and was accepted by the Pennsylvania Ornithological Records Committee earlier this year. The same bird turned up in Massachusetts in May 2017 but the Massachusetts Avian Records Committee rejected it.
In its summary the ABA Checklist Committee said "Acknowledging that this was indeed a difficult bird to assess, in the end, most committee members found no convincing evidence against natural vagrancy for this bird aside from extreme unlikeliness."
