Ground nesting bird advice

Hi,

I will be undertaking grassland surveys in the summer, and have been asked by some of the sites to present a method statement and risk assessment.  I realise my main point of concern is disturbing ground nesting birds, but as I have never written a risk assessment before I'm unsure as what to write other than that I will be careful in looking for signs of nesting birds, including warning calls etc.

Any help on examples of what to write in terms of this would be much appreciated!
