Nighthawk migration: On August 29, Tim Dyson & I counted migrating Common Nighthawks from Back Dam Park near Warsaw from 6-8pm. We tallied 133 birds, with one “flock”comprising at least 48. Quite a sight! Tim has already had several evenings in late August with more than 100 nighthawks. Nighthawks are designated as a Species of Special Concern in Canada (COSEWIC – 2018) Their population in southern Canada has declined by 68% since 1970, but the rate of decline has slowed appreciably over the past decade, and the species appears to be quite abundant in suitable boreal habitats.
American Chestnut update: On my efforts to re-establish American Chestnut: Lots of good news. First, all of seedlings that I started in the Spring have survived and seem to be thriving. Of course, we still have Winter to get through. Second, for the first time, all three of my most mature trees produced catkins this Spring, although I only see developing Chestnuts on two of them. I’m hopeful that I will be able to harvest many more viable seeds this Autumn than last. Third, and maybe most important of all, I discovered an American Chestnut sapling that must be at least five years old only metres away from the three original trees that I planted. Given its height (about a metre and a half) I surmise that it was planted by squirrels in the first year that the trees produced nuts. I have attached a picture. This is the proof I needed that the trees could self-seed up there, much earlier than I expected to have it.
