Crumbly curlew eggs may pose another threat to species, say UK scientists

Investigation launched after half of eggs from endangered wading bird in small study found to have fragile shells

A scientist has started a national investigation into curlews, after noticing in a small-scale study that some of the eggs being laid by the endangered birds were unusually fragile and crumbly.

If it emerges that the problem is widespread, the fragile eggs could pose a grave risk to the future of the species, which has declined significantly in Scotland, England and Wales and by 42% between 1995 and 2008 in the UK overall.
