Three days of offshore birding with predominantly medium to strong N–NE winds which are favorable for Pterodroma observations but quite hard on us, humans. Overall, a productive series of pelagic trips with the key species well observed. Steady passage of Cory's shearwater Calonectris borealis and Bulwer's Petrel Bulweria bulwerii everyday. Despite good coverage, hoped-for views of White-faced Storm-petrel or Barolo shearwater did not materialize.
