We spent yesterday motoring through the calm, perhaps not due north, but certainly north of the direct route and that following a tack north the previous night.  Last night the wind came in from the south west at 8:30 and we drifted through the night in a gentle breeze. 
 
This morning it arrived more determinedly and we have been reeling off 4 to 6 knots with the staysail poled out since the daily rain at 6:30.
 
Having set off to go north of the high, we have done it, or it moved south anyway.
 
 
Back to serious business:  You may have noticed me relating that the only birds are shearwaters  Did you spot the omission of a more accurate identification.  Now we do have four bird books on board, some small field glasses and a very small telescope. 
 
Our "Seabirds of the World" has 22 shearwaters in it, our American Audubon "Field Guide to Birds - Eastern Region" has 5, the Collins "Field Guide to Birds of Britain and Europe" has 4 but I cannot distinguish a Cory's from a Greater shearwater in any of them.   Up near Greenland it was easy as the white neck and rump markings of the Greater were clear.
 
However all is not lost, I found a little "Instant guide to Seabirds of the North American Coasts" which shows upper and lower markings of each.  The others are so proud of their photos that they never give views from above. 
 
So the final decision is as follows:  They are nearly all Cory's shearwaters round here:  500,000 pairs breed on the Azores, but the ones with very white rumps could be Greater shearwaters.  Of course some Cory's have very white rumps as well.
 
There were a lot of them yesterday, but this morning's drizzle, followed by spray as the wind gets up keeps me inside.  They may still be out there.  Nephew Miles will say that he identified them as Cory's shearwaters a fortnight ago.  OK, he was right.
