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: 
This is one of the reason why what we commonly think of as 'rules' of a sport are usually actually called 'laws'. See the [Laws of Cricket](http://www.lords.org/laws-and-spirit/laws-of-cricket/)

They are called Laws because you cannot possibly define to the very last possible detail every single possibility that might happen - such as the example here. In cricket the laws are applied by the Umpires and their ruling is final (except in some cases where technological challenges are allowed in certain circumstances).

So in the case here, the Umpire would apply [Law 32 (Caught)](http://www.lords.org/laws-and-spirit/laws-of-cricket/laws/law-32-caught,58,AR.html) - which states that one condition for a fair catch is that:

> 
> (ii) the ball is at no time in contact with any object grounded beyond the boundary.
> 
> 
> 

A bird in the air, is not grounded beyond the boundary

In addition it later states:

> 
> a catch shall be considered fair if .... (f) the ball is caught off an obstruction within the boundary that has not been designated a boundary by the umpires before the toss.
> 
> 
> 

The umpires are not going to designate a temporary phenomenan such as a bird to be a boundary so this would clearly be a fair catch, and the batsman would be out.
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.
