Olive-backed sunbird, perched at the base of a mirror on the bathroom building, seemingly admiring its own reflection. In the third picture, it flew up to the left part of the ceiling space.

Virtually every day for weeks, if I visited this bathroom in the early-mid morning, an olive-backed sunbird would be sitting at the mirror looking at itself, flying away when I or another person gets too close. Very amusing behavior! One of the divemasters said that they have been doing that for years.

Incidentally, the second picture shows off what I think is a clever mechanism for washing hands (the water bottle had small holes in the bottom).
