     Equipped only with a pair of binoculars (双筒望远镜) and ready to spend long hours waiting in all weathers

for a precious glance of a rare bullfinch (红腹灰雀), Britain's birdwatchers had long been supposed to be lovers of a minority sport. But new figures show bird-watching is fast becoming a popular pastime, with almost three million of us absorbed in our fluttering feathered friends.

     Devoted birdwatchers, those prepared to travel thousands of miles for sighting of a rare Siberian bird, are

fast being joined by a new breed of follower whose interest is satiated by watching a few finches (雀科鸣鸟)

on a Sunday walk or putting up a bird-box in the back garden.

     "Almost three million UK birdwatchers is certainly possible if you include everyone with only a casual

interest," Stephen Moss said in his newly published book.-A bird in the Bush: a Social History of Birdwatching

- which records the pursuit from the rich Victorian Englishman's love of shooting rare birds to the less

offensive observational tendencies of birdwatchers today.

     Television wildlife programmes have helped to fuel the new trend. Last summer, BBC 2's Britain Goes

Wild was a surprise success. It pulled in three million views and led to bird-houses selling out across the UK as

45,000 people promised to put up a box. Birdwatchers networking system first came to the attention of the

nation in 1989, when a birdwatcher caught sight of the first Vermivora chrysoptera-a golden-winged songbird

from North America-to be seen in Britain. He put a message out on the network service Birdline, and the next

day 3,000 birdwatchers proved the full pull of a truly rare bird as they visited the Tesco car park in Kent.,

where it had settled. Today, birdwatchers can log on to www.birdline.co.uk or have news of the latest sighting

texted to their phones.

      "Multimillion-pound spending on binoculars, bird food and boxes point to the increasing numbers of

birdwatchers." Said David Croack, the editor of Bird Watching magazine"The number of people involved is so

big that they have great potential to influence government decisions affecting the environment."
