Kishor has sent The Naked Scientists this question.

"The dry lands in central Australia become lakes unpredictably every few years and immediately attract birds and have fish in them. How do the birds know there is water and how do they navigate to get there?"

Dont know much about fish but birds migrate from location to location. It helps them find food, water, shelter for breeding & production, and safety from extreme weather. Also, bird hunting revolve around seasonal migration.
