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.

Engineered sandbars don't measure up for nesting plovers

Summary:
Dams reduce the creation of natural sandbars, which is bad news for birds that depend on them for nesting habitat. More than 200 hectares of engineered sandbars have been built along the Missouri River to address this problem -- but how does this compare to the real thing? A new study takes advantage of a natural experiment created by the region's 2011 floods, demonstrating that engineered habitat doesn't provide the benefits of sandbars created by nature.
