Scores of bird-spotters have flocked to the coast at Cromer this afternoon following sightings of a rare bird.

Attention - and binoculars - are focused on the citrine wagtail, which is believed to be in a field near Wyndham Park - on the coast road between Cromer and East Runton.

On www.birdforum.net, a bird alert was issued, with twitchers posting comments. Stuart White said: 'The first spring male in Norfolk? Very nice it was too.'

The citrine wagtail breeds in north central Asia in wet meadows and tundra. It migrates in winter to south Asia, often to highland areas. Its range is expanding westwards, and it is a rare but increasing visitor to western Europe.
