"O pássaro bebe água."

Translation: The bird drinks water.

[Kevin259675]

Why does this sentence not use "a agua" but the other example "A tartaruga bebe a agua" does use "a" before "agua"

[LobsangC]

You could say 'The bird drinks water' or 'The bird drinks the water'. Both would be correct with only very subtle differences in meaning, even in English if you think about it.
