How do birds drink? A robin takes a mouthful of water and then tips its head way back to send the water down its gullet. Pigeons are among the few birds that can suck in water with their heads down. Swallows and swifts skim a beakful of water on the wing. Gulls like this Western Gull can even drink salt water. If you have a birdbath, be sure to keep it clean. The birds' health is at stake.
