Frigatebirds
Two species (Great and Lesser Frigatebird) nest on the island. I have no idea how to tell them apart when they're perched...
... but in flight the size difference is obvious enough (2 Lessers, a Great and a Red-footed Booby pictured here).
Adult male Lessers also have a white axillary triangle which is absent in Great.
We saw several downy chicks,
and some smart red-headed fledglings.
Note the tick wedged in the base of this bird's bill.
