Yesterday I shared some images of last week’s flood at Mayslake Forest Preserve. When I saw how high the water had risen, I expected to find the Canada goose nest washed out. She was in the bowl-like parking lot marsh, on top of a muskrat house. When I got there I found that the water was high, but it had found a new outlet that limited its rise.
As I walked the east shore of Mays’ Lake that day, I heard a sudden loud splash above the roar of the nearby stream. It reminded me of a beaver’s warning dive, but there have been no resident beavers on the preserve in some years, so I passed it off as something else. On the next day, however, I found this:
Until I have reason to believe otherwise, I imagine this beaver was passing through, following the course of the flood or perhaps using the elevated waters to make an exploratory trip.
A final image comes from the day after the flood, as a northern rough-winged swallow rested at the edge of the lake.
This was a reminder that the spring migration is accelerating as the end of April approaches.
