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.

Bad news and good news for birds nesting at reservoirs


Date:June 25, 2015

Summary: In a six-year study at Arrow Lakes Reservoir in British Columbia, researchers found that while some nests failed due to flooding as the reservoir filled up in the spring, the higher water levels actually provided benefits for the nests that survived. Their results show that overall, nesting in the reservoir's riparian areas did not reduce nest success.More than half of the world's major river systems are regulated by dams and reservoirs. Many bird species rely on riparian habitat, building their nests in the vegetation that lines rivers and streams. However, whether they can find success nesting on the shores of reservoirs that are drained and flooded according to the needs of water storage rather than the needs of wildlife has been largely an open question.
