Condensation on metal Use cloth to absorb water, then wring water from cloth. Extreme temperature variations between night and day may cause condensation on metal surfaces. You should follow in the direction in which the trails converge. Signs of camps, campfire ashes, animal droppings, and trampled terrain may mark trails. Flocks of birds will circle over water holes.
Some birds fly to water holes at dawn and sunset.
Their flight at these times is generally fast and close to the ground. Birds tracks or chirping sounds in the evening or early morning sometimes indicate that water is nearby. If you do not have a canteen, a cup, a can, or other type of container, improvise one from plastic or water-resistant cloth. Shape the plastic or cloth into a bowl by pleating it. If you do not have a reliable source to replenish your water supply, stay alert for ways in which your environment can help you.
