As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Common cranes 'here to stay' after recolonising eastern England



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.
