Photo of Jim Wortham.We have just completed the survey in western Ontario. Our timing seemed to be perfect. Lakes were all thawed, trees have not leafed-out, and the birds are here and ready. The habitat looks great, but my concerns persist from last year regarding the beaver population. Many prime beaver marshes remain unoccupied, and as a result, water levels in these marshes are not maintained and the potential habitat is lost to nesting waterfowl. My rough estimates are that only about 60% of the potential beaver colonies are occupied. Next stop, Bangor, Maine to deliver this aircraft off for maintenance and inspection, and to borrow a sister aircraft to complete the remainder of our survey.
