Question: Lets say a batsman hits a shot and in midway it hits a bird in the air and then as soon as it hits the bird, the ball starts falling down and is caught by a fielder, will the batsman be given out?

I searched a lot all over but could find nothing about a rule which clarifies this, any help will be appreciated.

Answer: 
The rule for all indoor stadiums having roofs are that if the roof is closed and the ball hits the roof, then it is considered a dead ball.

Hussey [hits the roof](http://www.youtube.com/watch?v=OkcP5M2n-F0) with a monstrous shot.
I believe the first answer is incorrect.

If the ball hit a flying bird it would probably be called a *dead ball*, as I believe it has to go directly to a human fielder without touching *anything else* to be considered out caught. 

In the same way that if the ball hit a helmet on the ground, bounced up and someone caught it, it would be a *dead ball* and 5 penalty points awarded to the batting side.
