Observation details
Note from the experts: The documentation you have provided shows a Black Storm Petrel. This record was flagged by another eBird user with the following comment: "This looks like a very messy Black Storm-Petrel, note the shape of the paler covert panel, extends to include outer greater secondary coverts." This ID was confirmed by Alfredo Begazo, who also worked out a comparison between the two species that is about to be published. The main difference is extension of the light wing bar, which for Marhkam's Storm Petrel reaches the leading edge of the wings, while is stops short for Black Storm Petrel.
