Model predicts population of UK’s
tallest bird could double within 50 years after its return to the east of
England following a 400-year absence

Common cranes which recolonised
eastern England less than 40 years ago after a 400-year absence are now here to
stay, research has found.
There could be as many as 275
breeding pairs of the UK’s tallest bird within 50 years, scientists at the
University of Exeter, the RSPB and the Wildfowl and Wetlands Trust (WWT)
predict.
Cranes were lost from the UK as a
breeding bird in the 16th century as a result of hunting and the drainage of
large areas of wetlands, but some returned to the east of England in 1979.
Conservationists supported the
small population, but they breed slowly and their numbers remained low over the
next two decades, leaving the population at risk of disappearing again if hit
by problems such as disease.
A new population model, published
in a paper in the journal Animal Conservation,
found that an important part of the growth in numbers until 2010 were new
arrivals from continental Europe.
