   It is difficult to classify them precisely, but, in roughly ascending order of productivity, we now recognise the purely chance observer, the locality regulars (now recognising that ‘time in’ eventually equals ‘rarity out’), the ringers (particularly when working in groups), the occasional tally-hunter (most of us, if we are honest), the full-time observatory workers (exhibiting the highest standards of discipline) and the growing group of full-blooded rarity collectors (self-styled ‘twitchers’, covering individually up to 30,000 miles in their annual pursuit of ‘lifers’).

   Twitchers are very mobile and may travel great distances to see rare birds, of which they hear through their efficient 'grapevine'.

   I do not consider myself either a twitcher or an expert.
