Rockin’ the roads of Headwaters: Touring the landscapes of Headwaters

Our next field trip will be a Geology and Geomorphology Field Trip on Saturday Feb 13th. If you are a member of the Upper Credit Field Naturalists Club, you should have received a more detailed notice. If you are not a member … well … Our goal is to help us all learn how to see our local landscape in a way that’s more inter-connected and explicable than just seeing it as pretty and hilly. We’re going to look first at the general area of the old Orangeville brickworks, and get some idea of how that mix of clay and marl was deposited some 12,000 years ago. That involves learning about the Alton moraine plug that was dropped by the last glacial advance in this area when a lobe of ice temporarily moved back northwest across what is now Lake Ontario during a brief period of regrowth of the otherwise… Read more »

The reason for FLAP (Fatal Light Awareness Program)

We installed new windows at home over the summer. Several times we’ve heard ‘thunks’ as birds hit the large shiny new window in our now-bright living room. Then this … Look carefully at the photo. One wing extends right to the top and the other to the left edge; both legs show; individual feathers show; the breastbone clearly shows; individual feathers show … The dove survived initially, weakly flying away after a few minutes. The next day at our feeder there was a dove with feathers missing from its head. But after that, there have only been two Mourning Doves in our yard, down from the three that we’ve had for the last while. What is our living room with wonderful windows is not a living room for birds … We’ve now put up stickers and hung window ornaments — with success so far. Our next speaker from FLAP will be… Read more »

The Supermoon Eclipse — before the clouds eclipsed …

Four of us turned out at Island Lake to hope for clear skies — and we were in luck! Clouds covered the moonrise to the east, but the cloud-free western skies for sunset gave us hope. In the meantime, 5 cormorants flew to roost nearby in a remarkably flimsy dead tree, swaying in the light breezes. Muskrats dove in front of us, surfacing with winter vegetative clumps on which they munched while lying on the surface. At least three Killdeer called repetitively amongst themselves. Two Great Blue Herons foraged successfully in the shallows right beside us long into darkness.   The clouds stayed off low along the horizon to the east as the Moon rose above them. Shafts of high thin altocumulus rose westwards out of the bank of clouds. These shafts of cloud alternately covered and uncovered the eclipsing Moon, providing some gorgeous opportunities for photos. My trusty smartphone was pushed to… Read more »
