Bewick's swans: Baby boost for threatened birds
http://news.bbcimg.co.uk/media/images/64899000/jpg/_64899252_mhpdhb2uiw1joriinnb4-uofxzvam5fra_jxxuc-vi8,hocixiqgwjjhuzkfuli2mxtuphn2ioc_udh-8c0skss.jpgNorthwest Europe's threatened Bewick's swan population has been boosted by a bumper year for chicks.
Numbers of the bird have declined dramatically since the 1990s.
Up to 7,000 Bewick's swans usually migrate to the UK, arriving in October and flying back to Russia in March.
But surveys this year show the number of young among these wintering flocks has risen to 17.6%, compared to an average of around 10% over the past 10 years.
