Exploring Canada’s Creatures of the Night
In 2014, Nature Canada did our own night walk to look for nocturnal creatures. We began our walk along the dark trail guided only by the beams of light provided by our headlamps and flashlights. The low, constant hum of crickets could immediately be heard from the brush lining the path and was occasionally punctuated by the chirp of birds that had bedded down for the night. We approached our first bait station, located near the trail entrance, to see what creatures our fermented brew had attracted.
By day, Ottawa’s Mud Lake is host to a wide variety of active creatures from snapping turtles, to blue heron and all manner of insects, but by night, the wooded areas surrounding the lake transform and — if you’re lucky or have a particularly attuned set of eyes – a very different set of creatures can be seen. Mud Lake is also the site of Ottawa’s NatureHood program.
On this evening, a group of visitors had gathered at Ottawa’s Mud Lake to explore the often overlooked biodiversity of the area at night. Spotting nocturnal animals is a fun activity, but it’s also an important one if we are to know the makeup of Canada’s biodiversity.
We spotted a rabbit stopped to observe our group at one point, its eyes glowing eerily from the reflected light of our camera flashes. At our second bait station we encountered not moths, but a group of white banded ants that our sweet potion had attracted. The ants quickly scurried away from the gaze of our lights, but we were able to get a close look at a black spider that had set up a web between two bushes nearby.
As we made our way to the final bait stations, we stopped to look out on the lake. A muskrat bobbed up and down in the dark water as it made its way to the far shore.
At the final station we found that our bait had attracted a moth! It stayed still long enough on the tree for us to identify it as a sharp-winged shade. Based on what we know about moths (and our own limited success at spotting them at the Mud Lake nature walk) in the fall season, moths become more difficult to see due to falling temperatures. However, there are plenty of other nocturnal creatures that can be seen year-round in the Canadian environment.
Chris Earley is an Interpretive biologist at the Guelph Arboretum at the University of Guelph, where he’s been leading night time nature walks for close to 20 years. He says that many of Canada’s nocturnal creatures can still be seen when the temperature drops including: great horned owls, barn owls, flying squirrels, rabbits, coyotes and other small mammals.
“Nature walks are actually a great winter activity,” Earley said. “The freshly fallen snow makes it a very pretty environment to go owl watching.”
Earley leads evening nature sightseeing events and workshops called Owl Prowls in which a group of visitors learn about the creatures before heading out into a wooded area at the arboretum to attempt to spot or hear the owls using territorial calls.
Earley says going out and exploring Canada’s nocturnal creatures can lead to some interesting nature stories and sightings.
