Stantec has just released report #5, which covers the first half of 2011 on Wolfe Island. This was generally an uneventful report, with many of the patterns established in the first 4 reports continuing. At least I don’t have as many criticisms of Stantec as I did in my critique of their report #4. For instance, the power production on the days they did the survey wasn’t always minimal. Still, these reports continue to document just how much Wolfe Island has been impacted. Obviously bird populations vary widely from year to year for a number of reasons, and Stantec takes advantage of variation to present every possible reason why the populations are down, except of course to blame their turbines. Here’s the summary.
- Birds: 31 carcasses found, adjusted to 131, down from the report of a year ago.
- Raptors: 7 carcasses found, adjusted to 16, up a bit.
- Bats: 7 carcasses found, adjusted to 41, down from last year.
- Winter raptor density: improved from last year, at 0.54/km.
- Notifications: 6, half for raptors, half for Bobolinks. Continue reading Wolfe Island Bird Report #5
