Not sure if you saw my note Jane, but thought I should iterate that Fulmar would be quite unusual in this area at this time of year. So I think not a bird that could be confirmed based on a photo such as this.
Structure of 3 is wrong for Cory's.
Non-breeding prospecting Fulmars go to all sort of strange places in June.
I don't have any experience with Fulmars... but brown uppersides? OK call me out on "photo artifacts" but then what dictates that the head color is any more accurate? And Fulmar would be quite a rarity for that lattitude.
Irrespective of records, usual patterns, taking into account food source depletion etc , non-breeding Fulmars could turn up anywhere in the N.A, I'll stick with my initial thoughts.
[emphasis added]Difficult with these shots but 2 looks to be a Puffinus sp. so maybe a Manx, odd rear end? The 3 looks like a Northern Fulmar. Could be wrong..
I'd put my mortgage on bird 3 being a fulmar...
