Twitchers

I'm next to a little lake today.
There are a group of bird watchers just down the road hoping to spot something or other. Little do they realise that their presence is probably making the little tweets hide.
Maybe a group of people should hang out outside a twitchers house with binoculars and see how they like it.
Maybe they're just a bunch of bird pervs. I've seen that kind of thing on the net. Weird.
