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.

How are birds able to obey the speed limit?

Birds can judge the speed limit of a road, researchers at Cardiff University have discovered.

They found that birds are able to work out the average speed of a road and adjust their flight responses, in order to reduce the chance of crashing.

However this does make birds vulnerable to speeding cars, as they may not realise the vehicles are travelling faster than normal.

Dr Sarah Perkins, who was behind the study, told BBC Radio 5 live's Breakfast: "If you speed, the birds are in that area are adapted to the speed limit not your speed, so you may be more likely to cause wildlife roadkill."
