Bird Studies Canada’s (and CanWEA, MNR) July 2014 Bird/Bat Fatality from Wind Turbines Summary

birdcartoonBird Studies Canada  – why bother doing the summary if you know more than half the birds are not being collected? Why is the specific data on each projects ‘kill’ confidential? Do the wind companies own the wildlife here too? Seems like it. 

“In Ontario, 1,187 bird carcasses were found, comprising 118 identified species. Passerines were the most common fatality, representing approximately 69% of all bird fatalities in Ontario. The most prevalent passerine species found were: Golden Crowned Kinglet (9.39% of all bird carcasses found), Red-eyed Vireo (6.91%) and Horned Lark (5.39%). Raptors represented 8% of all bird fatalities, with Turkey Vulture (2.29%) and Red-tailed Hawk (3.99%) found most commonly. Gulls represent approximately 2% of all bird fatalities; with Ring-billed Gull (1.59%) the most often reported Gull species. Waterbirds represent approximately 2% of all bird fatalities, with Mallard (1.29%) as the most frequently reported waterbird species.

Table 4 lists the top 20 bird species found during post-construction mortality monitoring at wind power projects in Ontario and the proportion of carcasses found of each species, listed from lowest rank (most prevalent across sites) to highest rank (least commonly found). A full list of fractional rankings by species is available in Appendix 2.”

Table 4: The top 20 bird species found at wind power projects in Ontario based on fractional ranking and percent species composition. A full list of fractional rankings by species is available in Appendix 2.

Rank        Species                     % Composition

  1. Golden-crowned Kinglet     9.39%
  2. Red-eyed Vireo                      6.19%
  3. Horned Lark                          5.39%
  4. Purple Martin                        6.09%
  5. Tree Swallow                         8.79%

“The total number of operating turbines in Ontario as of February 2014 was 1,331 (CanWEA, personal communication) resulting in an estimated mortality of 7,250 bird fatalities (95% confidence interval of 6,236 to 8,265 fatalities) in Ontario between May 1st and October 31st based on February 2014 installed capacity.”


The mortality estimates presented here potentially underestimate true mortality as they are based solely on carcasses that fell within 50 m of the turbine base. It is expected that a certain proportion of birds and bats will fall outside of this radius, and there are several different approaches to quantifying this correction factor as can be inferred based on extrapolation of Figures 11 and 12. Zimmerling et al. (2013) reported that turbine heights were very similar (~80 m) for most turbines installed in Canada as of 2011 and estimated the proportion of carcasses expected to fall outside of 50 m to be up to 51.8% of birds, based on 4 studies that searched a radius up to 85 m. These values were further validated based on a field trial that searched up to 85 m from the turbine base (Zimmerling et al. 2013). Smallwood (2013) found that the proportion of both birds and bats that fell within 50 m of the turbine base varied with turbine height and estimated higher correction factor values for carcasses falling outside of 50 m than Zimmerling et al. 2013. Smallwood (2013) fit a logistic function to carcass distributions, and the proportions of carcasses falling within the search radius were calculated based on a variety of search radius and turbine height combinations. For 80 m turbines, carcasses were expected to fall to a maximum distance of 156 m. These findings indicate that the mortality estimates presented here may underestimate true mortality, but still allow for comparisons amongst sites and regions as long as turbine heights are similar; this is an important consideration for future investigation of landscape level factors and mitigation measures.”

  1. The Public Trust Doctrine:
    Implications for Wildlife Management and Conservation in the United States and Canada

    http://www.fw.msu.edu/documents/ptd_10-1.pdf

    “Defenders of the short-sighted men who in their greed
    and selfishness will, if permitted, rob our country of half
    its charm by their reckless extermination of all useful
    and beautiful wild things sometimes seek to champion
    them by saying that “the game belongs to the people.”
    So it does; and not merely to the people now alive, but
    to the unborn people.

    The Public Trust Doctrine (PTD), requires accountability of
    government for its actions in managing publicly
    owned assets. The public, as beneficiary of the
    trust, has legal rights to enforce accountability
    upon its government,

    These critical elements of the Doctrine were
    made clear in 1892

    ‘[excerpt] [rubber-stamped]: RECEIVED NORFOLK COUNTY Mayor’s Office Aug 10, 2005’

    ‘[excerpt] August 5, 2005

    Dear Mayor Kalmback and Members of Council,

    On behalf of AIM PowerGen Corporation (AIM) and Bird Studies Canada (BSC), we
    would like to update Council on recent discussions undertaken AIM and BSC
    regarding the Erie Shores Windfarm project. Following the Norfolk County Council
    meeting on July 12, 2005, staff of AIM and BSC agreed that it would be beneficial to
    meet again to discuss the project and to seek ways to address concerns regarding potential
    impacts of the project on bird populations. This meeting has taken place, and there have
    been a number of subsequent discussions among BSC and AIM staff.

    Both BSC and AIM have reiterated their strong support for ‘clean’ energy sources,
    including wind power. Similarly, both AIM and BSC agreed there are areas of mutual
    interest and concern with respect to windfarm projects. They relate principally to the
    appropriate siting of projects, monitoring for potential impacts, and mitigation measures
    during project construction and operation where necessary. We have discussed in detail
    BSC concerns regarding the proposed location of some windmills. Discussion focused on
    those areas located east of County Road 23, Gore Road, that are within or adjacent to: the
    Long Point Biosphere Reserve (and its Zone of Cooperation), the region’s
    internationally-recognized wetlands and two Important Bird Areas, important feeding and
    staging areas for waterfowl, coastal migration routes for raptors, and other areas
    identified as critical to region’s wealth and diversity of birds.

    AIM and BSC have both expressed strong interest in studying the further the potential
    impacts on birds of the Erie Shores project, and we are currently seeking funds to
    undertake this research. This research will build on studies undertaken by AIM as part of
    the approvals process, and build on the more than 40 years of data collected by BSC (and
    the Long Point Bird Observator and Long Point Waterfowl and Wetlands Research
    Fund).

  3. Also do they factor in the take count loss for the birds that obliterate upon hitting a blade, or the coyote and critter feast scarfed down in their guts?

    The story reminds me of a meeting with some wind scum and how great it was to our wildlife and they’d be totally safe, oh and what’s a tundra swan???? Shrug.

    I’m not kidding!

    • A PhD wildlife ecologist and a local hunter both doubted the low scavenger rates in consultants’ reports from Wolfe Island. I think it would be a relatively easy matter to independently quantify scavenger rates in a given area by distributing chicken heads (= little birds), etc. in a circle. Variables might include season, density, distance from center, time. (Scavengers return.) A good project for a student.

    • “Clear Creek wind farm up and running”
      Ashley House, Simcoe Reformer
      08/12/04

      TURBINES PRODUCING ENOUGH TO POWER 3,000 HOMES

      Six new wind turbines are winding up
      Norfolk’s contribution to a green energy
      grid.
      AIM PowerGen announced Tuesday
      the Clear Creek wind farm is officially
      online and producing 9.9 megawatts of
      wind power, enough to power 3,000 aver-
      age homes.
      A similar farm outside of Dunnville
      was powered up in October.
      It is the last of four projects the wind
      power developing company AIM Power-
      Gen commissioned in Ontario for 2008.
      In June, AIM’s wind farms in Cultus and
      Frogmore came online, adding 20 mega-
      watts to Ontario’s grid.

      The smaller scale operation, compared
      to Erie Shores Wind Farm commissioned
      in 2006, was fully operational Nov. 22 and
      connected right to Hydro One’s local dis-
      tribution lines.
      “This is one of the first projects to be
      connected to local distribution lines,”
      said David Timm, vice president of stra-
      tegic affairs with AIM.
      “We are greening
      the local community in a sense.”
      While all power is pooled into the
      provincial electric grid, electrons flow to
      the closest power load; meaning homes
      in Norfolk are being powered by these
      turbines.
      Completion of the project brings On-
      tario’s installed wind capacity to over 649
      MW, with 11 per cent of the power being
      harnessed here in Norfolk.
      While Timm said AIM will focus on
      other ongoing projects in Essex and Shel-
      bourne in 2009, the wind power developer
      is not losing interest in the wind power
      potential on Erie’s north shore.
      The company’s website indicates it
      is working on a feasibility study for off-
      shore turbines in Nanticoke.
      They are also in the late development
      stages of Phase 2 of the Erie Shores Wind
      farms, which includes infilling turbines
      between existing ones and extending the
      farm further west.
      They are awaiting
      procurement from the Ontario Power
      Authority.
      AIM is not the only person interested
      SEE WIND FARM/PAGE 2

      Wind farm
      CONTINUED FROM PAGE 1
      in harnessing wind power in
      Haldimand and Norfolk Coun-
      ties.
      “We’ve definitely had lots
      of inquiries,” said Chris Baird,
      general manager of planning
      and economic development
      with Norfolk County. “Because
      of our good source of wind we
      are looked at as favourable.”
      Earlier this week, Dover
      East Wind Limited Partnership,
      a division of Tribute Resources
      Inc., announced it hopes to
      construct 30 MW of generating
      capacity on 1,800 acres of the
      Nanticoke Industrial Park.
      Timm said it’s a combina-
      tion of many things, not just
      Lake Erie’s predictable wind
      source, that keeps generating
      interest in the county.
      “We’ve had great commu-
      nity support, interested land
      owners and a receptive com-
      munity,” Timm said.
