The big, black bumblebee we have on St. Martin is hard to photograph, but I discovered they like flowers from the passionfruit family. Also known as carpenter bees, they chew a tunnel into wood and build their nest there. I believe the species we have is Xylocopa mordax.
We have a bunch of these in our almond tree in Ebenezer Estate, Dutch Cul-de-sac. Sometimes you will see a golden version of the usual blue-black bumble bee.
