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.

Lasting severe weather impact found in feathers of young birds

Summary:
While studying a ground-nesting bird population near El Reno, Okla., a research team found that stress during a severe weather outbreak of May 31, 2013, had manifested itself into malformations in the growing feathers of the young birds. The team witnessed a phenomenon termed 'pallid bands' in a large proportion of fledgling Grasshopper Sparrows and found spikes in the chemical signatures of 'pallid bands,' which led to abnormalities in the new feathers.
