I could try that on my way up to Norfolk. Thanks Mark.
According to the July Bird Watching magazine, which came in the post today, my local patch at Gatwick Airport, which features in their Go Birding walks section, "Tree Sparrows are always present", so looks as though I'll have to start opening my eyes a bit more, because I've been about 30 times in the last year and never seen them. C'est la vie. I suppose my bird identification skills will eventually improve.
