A Canada Day Salute to the Canada Goose

Meet the Canada Goose, scientific name Branta canadensis, nicknamed the “cobra chicken” for its long neck, fierce hiss, and unapologetic attitude.

This Canada Day, we’re turning our attention to a bird that shares the nation’s name—and quite often, our sidewalks. The Canada Goose is a familiar sight across the country, especially here in Calgary, where they patrol pathways and riverbanks like feathered sentries. With their upright stance and unflinching glare, they’re quick to hiss at any passerby who drifts too close, particularly in early summer, when human families gather outside just as goose families are doing the same.

Yes, families. These so-called “cobra chickens” aren’t just being rude—they’re protecting what matters most.

Canada Geese are deeply social birds. They form tight-knit family units and even travel in extended groups of familiar individuals. While many geese migrate back north in the spring, Calgary is home to a hardy resident population that chooses to brave the cold winters alongside us. For both local and migrating geese, spring marks the beginning of the breeding season.

Two adult Canada Geese guide their brood of goslings through the water, keeping an ever-watchful eye out for danger.

Between March and May, females begin to lay eggs in nests made of dried grasses, lichen, and lined with the mother’s warm down feathers. The father, on the other hand, begins patrolling to protect his family. This is when those dramatic goose encounters tend to happen—the flapping, the hissing, the chase. However, it’s not aggression for its own sake; it’s vigilance, a father keeping watch over his vulnerable family.

Roughly 28 days later, the eggs hatch. Within hours, the goslings are walking, feeding, and swimming—tiny balls of fluff trailing behind their parents in a behaviour known as filial imprinting. This is a biological phenomenon in which a young animal forms a strong attachment to the first moving object it encounters, usually its mother. That imprint shapes their early learning, helping them identify their parents, follow them, and model essential behaviours like foraging, grooming, and swimming. It’s a kind of trust hardwired by evolution: follow the familiar, and you stay safe. Though flight won’t come until around 10 weeks of age, goslings grow quickly and master the basics within their first day. Still, they stay with their parents for up to a year, even completing their first migration with their family unit.

A Canada Goose leans in close, keeping careful watch as its fluffy gosling walks forward, because even the tiniest steps feel safe with someone big looking out for you.

Understanding this changes the story, doesn’t it? The hissing goose becomes a concerned parent. The waddling line of goslings is a symbol of care and learning. Suddenly, a park full of geese becomes a nursery, not a battlefield.

So what can we do to live peacefully alongside them? Keep your distance, especially during nesting season. Don’t feed them—human food can make them sick and encourages dangerous proximity to people and roads. Respect their space, and they’ll go back to grazing, paddling, and guiding their young without incident.

This Canada Day, let’s share our space with a little more empathy. The geese aren’t here to ruin the party—they’re just raising families of their own.
