By Labour Day weekend shorebird migration is well underway and some of the less common species start to arrive in our region. While the Eagleson storm water ponds are a great spot to find common species such as both Greater and Lesser Yellowlegs, Least Sandpipers and Semipalmated Sandpipers, the mudflats of the Ottawa River attract a variety of other birds, especially those that prefer tidal beaches and rushing water. Unfortunately, the water level of the Ottawa River depends not just the amount of rainfall we receive during the summer, but also the actions of the dam further upstream. We have received little rainfall this summer, as in most of our summers recently, however, this year the dam gates have remained shut so that the falling water levels have created the mudflats necessary to attract flocks of shorebirds. It has been great to see the sandbars emerge on the river on my daily bus commute along the Sir John A. MacDonald Parkway, and I was thrilled to see the mudflats developing at Andrew Haydon Park in recent weeks. This past weekend I went looking for shorebirds early in the morning, and the huge exposed muddy beach at Ottawa Beach was the best I’ve seen it in years. As long as the dam gates remain closed, this part of the Ottawa River shoreline will remain the best spot for viewing hard-to-find shorebird species throughout the fall given its accessibility.
