Almost perfect clean-up on their first day on the Azores with many vagrants and some locals ticked immediately.
Only a pelagic is needed then, they'll have everything they could've hoped for. They found several rarities by themselves, Bridled Tern being the most surprising one to me and only Solitary Sandpiper appears to have left the archipelago.
Their new list now includes
Cory's Shearwater
Snowy Egret
Semipalmated Plover
Grey-tailed Tattler
Buff-breasted Sandpiper (self-found)
Semipalmated Sandpiper (self-found)
White-rumped Sandpiper (self-found)
Roseate Tern
Atlantic Canary
plus Hudsonian Whimbrel, Atlantic Gull and Azorean Wood Pigeon.
If they manage to get Monteiro's Storm Petrel, Swinhoe's Petrel and Sooty Tern this would have again been a perfect clean-up like so many times before. As said above they'll likely get Azores Bullfinch in October and have several more shots at some tubenoses. There's also not that much left to chase in September in Britain, so they might consider to visit Cape Verde earlier to get the tricky tubenoses there, that they would currently not get.
