Black-capped Petrel returns to the Azores?

On 22 May 2009, a Black-capped Petrel (Pterodroma hasitata) was photographed at sea by João Quaresma some 5-6 miles south of Queimada, Pico. Interestingly, the first record for the archipelago was photographed off Graciosa on 26 May 2007. Photos of both birds are posted on the Birding Azores web site.
