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.

Snowy Owls Make Mysterious Migration

By Wynne Parry, LiveScience Contributor | December 06, 2013 03:57pm ET

The visitors from the Arctic have shown up as far south as North Carolina, on the island of Bermuda and in unusually large numbers in the Northeast and around the Great Lakes. Yesterday (Dec. 5), 15 were counted at Logan Airport in Boston.

For reasons no one understands, snowy owl sightings are spiking in eastern North America this winter.

"Maybe this is starting to shape up to be an irruption year," said Denver Holt, founder of the Owl Research Institute in Montana. 'Irruption' refers to the unpredictable migrations the birds make.
