You drink the seagull's blood, which is surprising very warm. It doesn't taste terrible, and is not as bad as you think. Aftering losing your quench for something to drink, you decide to have some of the bread in the bottom of the raft, and then you hear it, and helicopter flying overhead, hoping they spot you. Should you start yelling and screaming to make them hear you, risking the chance of not being heard, or look if you have a signaling device in the bottom of the boat, risking the chance of the helicopter being gone by the time you find it.
