My passion for wildlife was stimulated in my teenage years, mainly thanks to my Mum (a biology teacher) who made me look at the world differently and being inspired by writers such as Paul Colinvaux. This early interest developed into biological research in my 20s, when I did practical conservation work in places such as the Comores and Mongolia.
Today, any free time I have I spend pottering around the flatlands of East Anglia or escaping to our hut on the Northumberland coast looking for wildlife and castles with my wife and children.
I studied Biological Sciences at Oxford and Conservation at UCL, and worked at Wildlife and Countryside Link before spending five years as Conservation Director at Plantlife.
I joined the RSPB as Head of Government Affairs in 2004, became Head of Sustainable Development in 2006, before becoming Conservation Director in 2011.
It's mighty cold outside.
But the good news is that it's Big Garden Birdwatch this weekend.
This is your perfect excuse to spend an hour indoors sitting with a cup of coffee, watching birds in your garden.
And once you've finished, you could always turn on the telly and catch up with the wonderful Winterwatch on iPlayer...
Whatever you decide to do, I hope you have a great weekend watching wildlife.
