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.

Northern bird found to be more resilient to winter weather

One of the UK's most widespread songbirds, the Wren, varies in its resilience to winter weather depending on where it lives in Britain -- according to new research from the University of East Anglia and the British Trust for Ornithology.

Findings published today in the Royal Society journal Open Science reveal that Scottish Wrens are larger than those living in southern Britain, and more resilient to hard winter frosts.

Populations of small birds may decline following periods of cold winter weather, something that is probably linked to low temperatures and difficulties in finding sufficient insect prey.

Researchers at the British Trust for Ornithology (BTO) and UEA's School of Biology studied one of the UK's smallest songbirds, the Wren.

They found that populations inhabiting regions where winters are more severe show some form of adaptation.
