Perhaps you're thinking about:
* Animals that birds live *near* water: This would include fish, frogs, snakes, turtles, and many other creatures that live in or around aquatic environments.
* Animals that birds *prey* on: Birds often eat fish, insects, amphibians, and small mammals that live near water.
* Animals that birds *share* their habitat with: Birds often share their space with other animals near water, like mammals, reptiles, and amphibians.
Can you clarify your question a bit? What kind of animals were you curious about?
