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.

Waterbirds affected by low water, high salt levels in lakes

A recent study from researchers at the University of Montana, National Audubon Society, Oregon State University and East Cascades Audubon Society shows food sources for migratory birds decline with low water levels and high salt content in lakes.

The study is based on data gathered for more than 25 years at Lake Abert in Oregon, one of the most important stops for migrating waterbirds in the western United States. It found that as surface water levels decline, salinity increases and affects the availability of brine shrimp and other invertebrates -- a key food source for waterbirds.
