The dogs!
"I often get there before dawn, but it doesn't matter how early I get up, I can never beat the dog walkers - which I don't really mind. I like dogs. I'm not too fond of the dog owners though. Once I had an unfortunate incident with a Dalmatian called Brutus. His owner said that the dog obviously didn't like my aura. Five minutes later I thought of what I should've said:

"Madam, I'm afraid I cannot control my aura any more that you can control your dog!"

It was before 5 o'clock and I'd already been attacked by a psychic Dalmatian.

Up with the lark?... Up with the bark more like."

At Parliament Hill:
"It really is a bird's eye view from up on the hill. Any high place, especially above an urban sprawl, is likely to be a good look-out point to watch birds flying over. Mind you, you soon realise most of them are London pigeons. What I'm really hoping for is migrants. I often hear them before I can see them. They maybe call once or twice, but they don't land, they go straight over. Whilst I'm listening I can enjoy the remains of the dawn chorus. Blackbirds, song thrush and the herring gulls that nest around London Zoo. There are also blackcaps and yellow wagtails, which are a rarity on the Heath"

About the others users of Hampstead Heath:
"One of my problems is that people do sometimes go round doing bird impressions. Honestly. I've heard people quacking like ducks, honking like geese... cuckoos are quite common - people doing cuckoos I mean. And some of the dog owners have whistles that sound like birds. There's one bloke who calls his dog like a curlew. It fooled me once. But it's not a curlew, it's a Jack Russell"

Of his local patch overall:
"If someone asked me why I come here so often, I'd have to say 'cos it's my place, my local patch. I know it's not incredible, but it's not bad. And it's mine. Being out on Hampstead Heath sometimes drives me crazy, but I reckon I'd be totally nuts without it"
