Wind Farms and Red Kites www.assignmentpoint.com
The red kite is under threat in a number of European countries The causes include poisoning, closures of garbage dumps and feeding stations, shortages of live prey, electrocution, shooting, predation of the broods (e.g. by introduced species like racoons), etc. www.assignmentpoint.com
And here is a new one www.assignmentpoint.com

VULTURE MORTALITY IN SPAIN : • - Lekuona report, 2001 368 turbines 409 griffon vultures • - North of Soria : 200 griffon vult. • North of Castellón : 273 wind turbines 177 griffon vultures • one windfarm in Western Navarre over 100 griffon vultures • Tarifa dozens of griffon vultures (and 6 egyptian vultures) • No cumulative study… • 1,000-2,000 griffon vultures a year www.assignmentpoint.com

In all likelihood, their disappearance is due to death by collision, for there is no evidence that red kites are afraid of windfarms. Besides, open-space raptors are often seen flyingclose to wind turbines (Dr Lekuona 2001, Dr. Smallwood 2004) www.assignmentpoint.com
There are only 310-400 breeding pairs of Red Kites in Italy. ALTURA warn that 15,000 wind turbines in their country would be a major factor in the extirpation of the Red Kite, the Egyptian Vulture, and the Bonelli’s Eagle. www.assignmentpoint.com

WILL MITIGATION HELP? • THE ALTAMONT EXPERIENCE • - Moving the turbines • Repowering • Land management • Stopping the turbines part time • Mostly unsuccessful www.assignmentpoint.com
THE TASMANIAN MITIGATION (WOOLNORTH windfarm)unsuccessfulRADARSimpracticalTHE SMOLA-TYPE MITIGATION(the omerta) will cause many more deaths www.assignmentpoint.com
IT HAS BEEN DOCUMENTED THAT RAPTORS FLY CLOSER TO WIND TURBINES THAN WOULD BE EXPECTED BY CHANCE ( Thelander et al. 2003 ) www.assignmentpoint.com
The recently-moved topsoil around wind turbines attracts burrow-dwelling rodents that attract raptors. www.assignmentpoint.com
The latest report from California found another important reason : DECLIVITY WINDS www.assignmentpoint.com
Raptors and windfarms use slopes and ridges exposed to the prevailing winds www.assignmentpoint.com
Raptors and windfarms are therefore…. on a collision course www.assignmentpoint.com
And the raptors are losing www.assignmentpoint.com

Decline of the rare Egyptian vulture: new study, Estación Biológica de Doñana: biggest drop in nest sites where windfarms have been built www.assignmentpoint.com
The new census of the Egyptian vulture population is what led to this finding. Martina Carrete believes that similar conclusions may be drawn about other raptor species when their populations are next censed. www.assignmentpoint.com
For 6 years, I have myself been trying to warn bird societies that this was bound to occur. Earlier this year, Spanish Birdlife (SEO) responded by an apparent change in policy. Let’s hope other bird societies will respond before it is too late. www.assignmentpoint.com
LATEST REPORT FROM ALTAMONT PASS WINDFARM, CALIFORNIA (Dr Smallwood et al. 2009) reveals that mortality at windfarms has been underestimated. www.assignmentpoint.com
62 tubular-tower wind turbines totalling 22 MW killed by collision 115 raptors per annum - highest raptor/turbine mortality in the world. Dr Smallwood et al. 2009 www.assignmentpoint.com
UNDERESTIMATION, WHY ? • - The swamping bias • - The no-find bias • - The search frequency bias • The crippling bias (previous picture) • - The radius bias • The outsider bias • (Dr Smallwood et al. 2009) www.assignmentpoint.com
CONCLUSION : Unless a minimum setback of 3 km is respected between wind turbines and red kites’ nests and roosting places, the red kite could be headed for extinction. www.assignmentpoint.com
