Getting twitchy

Our thoughts, and those of Bird Watching columnist David Lindo, AKA The Urban Birder, have been turning to twitching these last couple of days.

The reason? A Dusky Warbler - London's first - discovered at Lockwood Reservoir, Walthamstow. It's around the allotments on Black Horse Road, E17, if any of you are interested in going after it. So far, the weather has stymied David, but we don't reckon he'll resist temptation for too much longer.

It's another sign that spring's on the way. In early January, it's easy to vow only to bird your local patch this year, but the closer the spring migration period gets, the more you start to think: "Well, maybe I'll twitch the odd county rarity".

We'll be looking at the psychology of twitching, and of birdwatching more generally, in the magazine in the near future, but what are your thoughts on it? Where do you draw the line? And what birds might lure you into a madcap overnight motorway dash to the other end of the UK?
