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.

Wind farm turbines take toll on birds of prey

EAGLES, falcons and other raptors make up to a third of the estimated 1500 birds killed each year at Australia’s biggest wind farm.

The finding of an independent report for Macarthur Wind Farm operator AGL follows 12 monthly searches of 48 turbines at the 140-turbine operation in Victoria.

After adjusting for birds eaten by scavengers between searches and the total 140 turbines, Australian Ecological Research Services estimated each turbine killed about 10 birds a year.

The analysis said this would include 500 raptors a year.

AGL has confirmed that 64 bird fatalities were found during the official searches and an ­additional 10 carcasses were found near turbines by maintenance personnel, landowners or ecologists when not undertaking scheduled carcass searches.

The total included eight brown falcons, seven nankeen kestrels, six wedge-tailed eagles, one black falcon, two black-shouldered kites and one spotted harrier.

But an AGL spokesman said the report had “shown no significant impact on threatened ­species”. The company said overall ­estimates of bird and bat mortality “are subject to several sources of bias which may result in inaccurate estimates”.
