Just as a quick follow-up, I was just down on Cayman Brac for two weeks of diving. Once work gets caught-up some, I'll work in the UW photo album.
First, I did apparently catch a very good sale on Cayman Airways. They're reportedly happening fairly frequently, so keep an eye out.
Also, be aware that the official flight itinerary isn't necessarily being followed faithfully right now, because because the Postmaster on Little Cayman is currently ill, so they're flying a post officer who lives on the Brac over to Little every morning, and back home to the Bracevery afternoon, and the official flight schedule doesn't always have a LYB --> CYB afternoon flight, so they have to "make one" right now. What happened with us was that our flight from Grand to Brac was on Wednesday ~5pm and they combined our flight with the Grand-Little flight ...
and everyone's checked baggage to the Brac was left behind on Grand without telling us. Fortunately, all of our checked baggage arrived that same evening on the ~8pm (Brac arrival time) flight.
On the subject of Queen triggers, I previously said:
Agreed & understood; our interpretations of rare-uncommon-frequent-common-etc are imprecise...by your scale, perhaps I should have only said 'uncommon. In the Sister Islands, I'd say a 75% chance on a dive; IIRC, my record is ~10 unique individuals on a single dive.
Purely by coincidence, I dived the first week with a Marine Biologist from Colgate and we talked about reef health, human impact factors & Queen triggers. What she explained was that they are a minor "indicator species" of a sort (by absence) because they prefer to eat a specific type of algae, and this algae tends to decline from human development. Thus, the flow-down causality is: (more humans) --> (less algae of the type that QT's like) --> (fewer Queen Triggers).
I also tried to remember to keep an eye out for Queens during my dives to try to gage frequency. I did so pretty well for the first several days, but didn't remember to do so for every single dive. For the dives in which that I did remember to specifically look, I saw at least one Queen on nearly each of them...call it close to a 90% success rate.
In other news, I didn't see the killer whale pod this year, but future visitors to BRBR might see the print of one my photos of them from last year that I gave to Mick now hanging up in the dive shop.
