Beauties Dave...and, did you know that "Bassanus" is actually derived from The Bass Rock, in the Firth of Forth, east of Edinburgh...?
The largest single island Gannet colony in the world with over 150,000 of them on the Rock. SO many of them, that the rock is actually white from their poo....
Almost certainly the bird would be named after the rock as the binomial naming system wasn't around before the 1750s and it seems the island was referred to as Bass Rock way before then. Interesting though.
There are a number of "basses" about in Scotia, predominantly hilly prominences, rocks or mounds which were used in Pictish and Medieval times as hill forts...
