I had just started so my advice is limited but I shall recommend a book I picked up in Guernsey. It is 'Important Sites for Birds in the Channel Islands' and the ISBN is 0-9518075-7-9, it was £7.80 there. You could do a google search for a source of the book. It really is an excellent little book.
Are you listening to the voice that talks in your head while you read this?
