Bird brought back from brink of extinction
    2018-07-19  08:53    Shenzhen Daily

BRITAIN’S tallest bird, the common crane, is to stay after being brought back from brink of extinction for the second time.

The crane was extinct in the U.K. for 400 years until two from continental Europe landed in 1979 and set up home in the Norfolk Broads. However even by 2015 there were only 20 breeding pairs.

There had been fears the U.K. could lose the birds, which can be more than 1.22-meter tall, again as they are threatened by foxes and breed slowly, rearing one or two chicks at a time.

But conservationists who brought in 90 cranes from Germany between 2010 and 2014 are believed to have given the species the chance to thrive. A study led by the University of Exeter has found Britain could have as many as 275 breeding pairs in 50 years. In 2016, the latest figures available, there were 48 pairs, says the RSPB.

The imported birds have interbred with those already living in Britain. There are now populations in Gwent, Gloucestershire, Norfolk, Suffolk, Yorkshire and East Scotland.

The authors of the study, which also involved the RSPB and the Wildfowl and Wetlands Trust, say the next challenge is to ensure there is enough suitable wetland available for the birds, which pair for life, to breed safely.

Andrew Stanbury, an RSPB conservation scientist and co-author of the paper in the journal Animal Conservation, said, “It is always great to get the opportunity to celebrate a real conservation success story and U.K. cranes is one of these.”
