How crow get water from bottle bottom.

A crow needs to get water from the bottom of a bottle, it may use its beak to tap and peck at the bottle. If the bottle has a narrow opening, the crow may use its beak to push a small stick or leaf through the opening to reach the water. Some crows have been observed using tools like twigs or leaves to make the water level rise so that it's within reach. For example, a crow might drop a small twig or leaf into the water to create ripples, or push a larger object like a pebble or stick into the container to displace enough water that it can reach the liquid. Crows are intelligent problem-solvers and can use a variety of techniques to get the water they need in different situations.
