When darkness falls over Canada’s vast wilderness, a symphony of mysterious sounds fills the air. From haunting calls echoing across northern lakes to eerie howls drifting through prairie grasslands, nighttime brings out some of nature’s most fascinating vocalists. Understanding these sounds connects us to the wild creatures sharing our landscapes.
Animal behavior can vary by region and season. Always observe wildlife from a safe distance and follow local guidelines when exploring natural areas at night.
1. Loon (Common Loon)

Few sounds are more Canadian than the loon’s haunting wail echoing across a quiet lake after sunset. This iconic water bird produces four distinct calls, including the tremolo, often called the “crazy laugh,” which signals alarm or excitement.
Their yodel call is used by males to defend territory and can carry for kilometres on still nights. Loons are most vocal during breeding season from May through July on northern lakes.
2. Great Horned Owl

A deep, resonant “hoo-hoo-hoo, hoo-hoo” announces the presence of Canada’s most widespread owl species. These powerful predators use their distinctive hoots to communicate with mates and warn competitors away from their hunting grounds.
Males typically hoot in a lower pitch than females, creating duets during courtship season. Found from coast to coast, their calls are among the earliest signs of breeding activity, starting in winter.
3. Coyote

Nothing quite matches the wild chorus of coyotes yipping and howling under starlit skies. Their vocalizations serve multiple purposes: announcing location to pack members, defending territory, and celebrating successful hunts with group sing-alongs.
A single coyote can sound like several animals through varied pitches and rapid changes. These adaptable canines have expanded their range across all Canadian provinces, bringing their nighttime serenades to urban areas too.
4. Tree Frog (Spring Peeper)

Despite measuring barely larger than a thumbnail, spring peepers create an absolutely deafening chorus on warm spring nights near wetlands. Each tiny frog produces a high-pitched peeping sound by inflating its throat like a bubble, creating waves of sound that signal winter’s end.
Males call to attract females, and when hundreds gather, the collective noise can reach 100 decibels. Their singing peaks during April and May across eastern Canada.
5. Grey Wolf

The long, mournful howl of a grey wolf represents one of nature’s most spine-tingling sounds. Wolves howl to rally pack members before hunts, locate each other across vast distances, and strengthen social bonds within their family groups.
Each wolf has a unique voice, allowing pack members to identify individuals by sound alone. Howling sessions often trigger responses from neighbouring packs, creating conversations across northern Canadian wilderness.
6. Crickets

The rhythmic chirping of crickets forms the background soundtrack to Canadian summer nights. Male crickets create their familiar sound by rubbing specialized wings together, a process called stridulation, to attract potential mates and warn away rival males.
Temperature directly affects their chirping rate, with faster chirps on warmer nights. Some species chirp at such predictable rates that you can estimate temperature by counting chirps per minute.
7. Beaver

While beavers themselves are relatively quiet, their warning signal is unmistakable: a loud slap of their flat tail against water that sounds like a gunshot echoing across ponds. This alarm alerts family members to potential danger from predators or human presence.
The slapping sound can carry surprisingly far on calm nights. Beavers are most active during twilight and darkness, making this their primary communication time around lodges and dams.
8. Barn Owl

Unlike the hooting of typical owls, barn owls produce an eerie, raspy screech that sounds almost otherworldly in darkness. This harsh, hissing shriek has inspired countless ghost stories in rural communities where these pale, heart-faced hunters patrol farmlands and grasslands.
Their calls serve territorial purposes and help pairs coordinate during breeding season. Barn owls remain relatively uncommon in Canada, found mainly in southern regions near agricultural areas.
