It's Behind You!
That's the cry that goes up in pantomime when the villain sneaks up on the hero or heroine, the audience can see what's happening but the hero can't. This must be what it feels like to be a young laysan albatross. Lurking beneath the waves, out of sight, is a deadly foe - a tiger shark.
The young birds do not have the skill to take off from the surface of the water, which as you can see from these series of still images, taken from NHNZ Images video, is not an easy task for such a large bird as an adult albatross.
There's considerable wing flapping, and running along the surface of the water before final take-off.
The plumage of young birds is not quite so water-proof, and once they land of the sea surface they can quickly become bedraggled.
Crash-landings in the sea are quite common amongst the youngsters just learning to fly.
They are then unable to take-off, and become a sitting target for tiger sharks patrolling the shallow coastal waters.
It only takes a few seconds for the shark to grab its victim, pull it under and eat it.
Tiger sharks are voracious hunters. Each summer the sharks congregate just as the young birds fledge from their Hawaiian nesting grounds.
