On November 30th I spent some time at the Eagleson Ponds looking for migrants. I haven’t been able to get out as much as I would have liked these past few weeks, and with the days getting colder (some days have not even reached as high as 0°C recently) I have felt even less inclined to go out – my tolerance for cold has plummeted these past few winters, leaving me with no desire to get out first thing in the morning when it is well below zero. When it warmed up to -1°C after four subzero days in a row, I decided to take advantage of the nice weather to head out to the ponds in the afternoon just to see what was around. It was a cloudy day with no wind, perfect for scanning the flocks of geese still around.

By the time November arrives, all but the hardiest of insects have vanished, leaving only those few species that are adapted to the cold temperatures of mid-autumn in Canada. The last dragonfly on the wing here in Ottawa is the Autumn Meadowhawk, a small red or brownish dragonfly with very little black along the abdomen and yellow or brown legs. It is these two traits that make them easy to distinguish from other local meadowhawks – the other common species have distinct black markings on the abdomen and black legs. The most similar dragonfly in our area is the Saffron-winged Meadowhawk, which also lacks distinct black abdominal markings. However, the Saffron-winged Meadowhawk is larger, usually has a noticeable amber-coloured tint to the leading edge of its wings, and has black legs with brown stripes. In addition, most of the other meadowhawk species are gone by mid-October.
