Mitigation?  What mitigation, we don't need no stinking mitigation!
To paraphrase Mel Brook's "Blazing Saddles" (1974)

Bird and raptor allowable mortality threshold rates in Ontario have been set equal to the highest ever recorded in North America.  The Industrial Wind Generating Installation at Wolfe Island has consistently approached those thresholds in every reporting period since the plant started operating in May 2009.  Birds killed include: birds listed as "threatened" (Chimney Swift & Bobolinks), raptors, and 25 other species of birds. To date Environment Canada and the Ontario Ministry of Natural Resources have recommended no mitigation actions other than ongoing monitoring.  Presumably when all the raptors and other birds which migrate along this major migration route have had their numbers sufficiently reduced,  the problem will be solved and no further mitigation will be necessary.

What can we expect the cumulative bird mortality to be once Ostrander Point, Amherst Island, Wolfe Island Shoals & 22 other Industrial Wind Projects to be constructed in the area come online?  The MNR treats each project in isolation and doesn't appear to consider the cumulative effect of so many Industrial Wind Plants being constructed across a major migratory flyway.  They also don't consider the cumulative effect on watersheds, erosion or the impact this Industrial checkerboarding will have on the long term viability of Ontario's biodiversity? 

The climate is variable.  If nothing else has come from 12 years of climate science, this has.  No one disputes that the climate gets warmer and colder over time.  If our climate is indeed warming at present (and there is some legitimate doubt about that), whether caused by humans or nature or a combinaion of both, the accepted theory is that in attempting to adapt to changing conditions our flora and fauna will migrate from southern regions to more northerly regions.  How will the Industrial Checkerboarding of the Lake Superior watershed and our boreal forest, which our Ontario Government wants to carpet with thousands of IWT, help sustain biodiversity and allow our endangered natural heritage adapt to a changing climate?  The more wilderness is fragmented the less carrying capacity it has and the greater the percentage of its flora and fauna that become extirpated if not extinct (1)

But the Ministry of Natural Resources is not interested in such considerations.  The MNR's priorities are evident in the phrasing to be found at the start of EBR postings related to the GEA and REA:

"Ontario wants to make it easier for businesses to apply for and obtain environmental approvals in a way that increases protection of the environment. That's why we've created a new environmental approvals process that will create a more efficient, user-friendly approach that continues to fully protect the environment."

Note that the priority is making it easier for business and more "efficient" and "user friendly".  The environment is last in both sentences.  Furthermore our environment is not currently 'fully' protected.  I'm also unsure how building hundreds of kilometers of 20m wide roads able of carrying 50 to 100 tons of equipment, clear cutting hundreds of acres of carbon sink forest, disrupting wetlands and spawning streams, and pouring hundreds of thousands of tons of cement on which oil-leaking IWT, which catch fire, will be erected and connected to the US export market via thousands of kilometers of new high voltage transmission towers, which will have to be cut through our untouched wilderness, "increases protection of the environment".

Update 4 May 2011:

Wole Island now has the highest raptor kill per turbine in all of North America.  The MNR's soution:  another year of monitoring, the last required of the project.  We may well ask ourselves, then what?

Thanks to Helen for this picture of Darryl Mueller in 1993, holding a Golden Eagle killed by an Industrial Wind Turbine at Altamont Pass, California, USA, another person who fought single-handed to protect eagles from turbines, in this case at Altamont Pass, for many years.

Another interesting article, also to be found on Springerlink, deals with the possility that the colour IWT are painted has a marked effect on insect attraction.  It would appear that by painting IWT with paints which have minimal IR & UV properties, we can siginficantly reduce the way they attract insects and consequently bats and insect eating birds.  Apparently purple is the least attractive colour to insects.  This may not reduce raptor mortality, but may help significantly reduce other species of birds, as well as bats, killed by IWT.

When attending proponent open houses and meetings, or corresponding with the IWT company make sure you bring this to their attention and request that they paint their IWT purple.  If they refuse, ask them why.  Get answers in writing when possible.  Write or email the MNR in Peterborough and ask them to require IWT companies to paint their turbines purple as a mitigation measure to reduce bird and bat mortality.  Bring the company's refusal to the MNR's attention.

Insect attraction to wind turbines: does colour play a role?

C. V. Long, J. A. Flint and P. A. Lepper

The phenomenon of wildlife mortality at wind turbine installations has been generating increasing concern, both for the continued development of the wind industry and for local ecology. While an increase in aerial insectivore activity in the vicinity resulting from insect attraction to turbines remains a strong possibility, little research exists on the possible causes for such events. In this paper, the relative attraction of a selection of specific turbine colours and other hues is assessed in order to determine if turbine paint colour could be influencing insect numbers at these installations. The common turbine colours ‘pure white’ (RAL 9010) and ‘light grey’ (RAL 7035) were among those found to attract significantly more insects than other colours tested, suggesting colour may well have a role to play in potential mitigation.

Habitat Fragmentation Effects on Birds in Grasslands and Wetlands: A Critique of Our Knowledge
Douglas H. Johnson

Abstract
Habitat fragmentation exacerbates the problem of habitat loss for grassland and wetland birds. Remaining patches of grasslands and wetlands may be too small, too isolated, and too influenced by edge effects to maintain viable populations of some breeding birds. Knowledge of the effects of fragmentation on bird populations is critically important for decisions about reserve design, grassland and wetland management, and implementation of cropland set-aside programs that benefit wildlife. In my review of research that has been conducted on habitat fragmentation, I found at least five common problems in the methodology used. The results of many studies are compromised by these problems: passive sampling (sampling larger areas in larger patches), confounding effects of habitat heterogeneity, consequences of inappropriate pooling of data from different species, artifacts associated with artificial nest data, and definition of actual habitat patches. As expected, some large-bodied birds with large territorial requirements, such as the northern harrier (Circus cyaneus), appear area sensitive. In addition, some small species of grassland birds favor patches of habitat far in excess of their territory size, including the Savannah (Passerculus sandwichensis), grasshopper (Ammodramus savannarum) and Henslow's (A. henslowii) sparrows, and the bobolink (Dolichonyx oryzivorus). Other species may be area sensitive as well, but the data are ambiguous. Area sensitivity among wetland birds remains unknown since virtually no studies have been based on solid methodologies. We need further research on grassland bird response to habitat that distinguishes supportable conclusions from those that may be artifactual.
