@navjeevan dadwal,
Try asking this question to someone like the RSPB (you'll easily find their website) as they are very helpful with pointing you in the right direction on this type of thing.
A good book would be 'The Biostatic Cookbook: The most user-friendly guide for the Bio/Medical Student.'
A quick search on something like Amazon would give you more details on this and similar books.
Then again, we may have a resident expert arriving any second, but just in case they don't, .......
