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.

Bird migration changes on Fair Isle revealed

A major survey into bird migration from Africa over the past 60 years has revealed substantial changes in behaviour.

The Fair Isle bird observatory has recorded bird migration at its station between Shetland and Orkney since 1938.

A new initiative - the Fair Isle migration project - has now analysed records from the sanctuary since 1955.

The study has also revealed changes to the times of the year the birds are migrating.

The research has concluded spring migration has happened much earlier in recent years for many species, such as the swallow, which is arriving up to three weeks earlier than the birds did in the 1950s.

For other species, such as the willow warbler, spring migration has occurred much later.
