Fall Arrives

Mourning Dove

On the final Wednesday in September the weather finally changed. Once again the temperature climbed into the 30s, but a cold front passed through around 3:00, generating a powerful but short-lived thunderstorm that brought many tree limbs down. This was the first rain we’d had in three weeks. The temperature fell about seven degrees, and since then temperatures have been back to seasonal, falling to single digits in the night and rising to about 15°C in the day. It’s now necessary to wear a coat in the morning, but I find the change refreshing.

Snippets from Late Summer

Late summer is a great time for birding. Shorebirds, flycatchers, and warblers which breed further north have moved into the area, while our resident breeding birds are preparing for their journey south. It’s a fantastic time to check out the woods and river for both residents and migrants before they leave for good. Personally, it’s one of my favourite times of year, especially as the summer weather tends to linger on into the end of September – unlike the fickle weather of May, you can go birding in shorts and sandals instead of gloves and winter coats. The diversity is just as excellent, and it is possible to find species that usually bypass Ottawa in the spring lingering here in the fall. Here are a few things I’ve found recently while out birding around the west end.

Great Black-backed Gull

Curious Wood-Pewees

Eastern Wood-pewee

On July 10th I took the day off work and went birding. It was another overcast day, and I found myself at Shirley’s Bay to see how bad the damage was to the dyke from the spring flooding. Although I was warned that it was bad in spots, I was allowed to go out birding on the dyke by the DND Range Control. While some areas had been heavily eroded, the part birded by most people – about halfway to the first island – was fine. After that it began to resemble the crumbled path between the first and second islands, with huge chunks of earth torn away. I did not go any further, though I was curious if anything was left between the two islands.

My attention was immediately caught by an adult Bald Eagle perching in a tree right out on the dyke, though it flew off before I could get close to it. I heard a Common Gallinule, two Common Yellowthroats, and several Marsh Wrens in the reeds, and saw an Osprey flying over the water. Two Spotted Sandpipers, a kingfisher, and a Common Tern were also present along the dyke. I didn’t stay long, as there wasn’t much of interest right in the middle of breeding season, and there was no shorebird habitat yet for early migrants heading south.

Life Among the Milkweeds

When most people think of milkweeds and the insects that are associated with them, they think of the iconic Monarch butterfly, which subsists solely on these plants in its larval stage. Others may recall the beautiful Red Milkweed Beetle, the black and orange Small and Large Milkweed Bugs, or the fuzzy Tussock Milkweed Moth caterpillars that sometimes gather together in groups of a dozen or more. However, milkweeds are an abundant source of nectar and pollen for many types of insects, and these in turn attract predators searching for easy prey. If you spend some time examining these plants at the height of their flowering season, an amazing secret world opens up, as all kinds of colourful creatures can be found on their flowers and leaves. Here are a few of the colourful and intriguing creatures I photographed in early to mid-July while looking for the more common butterflies and dragonflies.

Rain and Flooding in Ottawa

After one of the wettest Aprils on record, both the Ottawa and Gatineau Rivers have burst their banks, causing extensive flooding that has affected hundreds of homes on both sides of the provincial border. A combination of snow melt flowing into the Ottawa River through its various tributaries and the high volume of rainfall this spring caused the water to rise faster than could be controlled by engineers at the various dams along the river. The Ottawa River is the highest it has been in decades, and neither I nor the long-time birders here have seen anything like it.

This month alone (now only seven days old) has seen over 100 mm of rain, with 45mm rain on May 1st, 40mm on Friday, and 20 mm yesterday. In the 24-hour period between Saturday afternoon and Sunday afternoon, the Ottawa River rose 17cm, and, according to the Ottawa River Regulation Planning Board, is expected to rise a further 5cm before its peak on Monday. A state of emergency has been declared in Gatineau, where the Canadian Forces was on hand to help police reach difficult to access areas. On the Ontario side, Cumberland and Constance Bay were the two areas affected most, followed by Britannia, Dunrobin, Fitzroy Harbour and MacLarens Landing.

Late October Sightings

Black-crowned Night-heron

Although migration continues to progress, I haven’t seen as many late-season migrants as I had hoped. Still, there have been a few highlights during the last week of the month, including the arrival of some of our winter birds.

I headed out to Shirley’s Bay on Sunday, October 23rd, but the wind was so cold and blustery that I didn’t spend much time there. I saw a Merlin perching in a tree along Rifle Road and found my first Snow Buntings of the fall picking their way along the shore. There were only two of them, and they flushed when a couple of photographers got too close – I don’t think they even realized they were there. They may have been trying to get close to a Common Loon swimming fairly close to shore, unremarkable in its gray winter plumage.

Dragon-hunting at the Bill Mason Center

On August 7th I met up with Chris Lewis at Shirley’s Bay for a morning of birding and dragon-hunting. The morning got off to a great start when I saw a group of Wild Turkeys along Rifle Road even before I met Chris at the parking lot; there were two adults and a couple of baby turkeys! As soon as I stopped the car the adult turkeys began herding their offspring away from the road. Although they weren’t that close to begin with, it was cute to watch the babies stop and peck at the weeds while Mom and Dad steadily walked toward the back of the meadow. I’ve seen Wild Turkeys in that field before, but this was the first time I’d seen them with any young, and it was a thrilling experience.
