Discover why American Robins aren't always a sign of spring. Learn about their winter habits, food searches, and why many stay in Canada year-round.

When we think of the first signs of spring, many of us picture the cheerful song and bright orange/red breast of the American Robin. But what if we told you that spotting a robin doesn’t necessarily mean spring is on its way?

While it’s true that American Robins are often associated with warmer weather, many stay in Canada throughout the winter rather than migrating south. So, why do some robins stick around, and what are they up to during the colder months?

Why Don’t All Robins Migrate?

Migration for robins isn’t as straightforward as it is for other bird species. Unlike birds that migrate due to temperature changes, robins migrate primarily based on food availability. In the fall, many robins head south in search of fruit-bearing trees and shrubs, their primary winter food source. However, if robins can find enough food locally, there’s no need for them to make the long journey south.

Some robins also take advantage of urban areas, where fruit trees, ornamental shrubs, and even backyard feeders (with fruit and mealworms) provide a steady food supply. These adaptable birds can find what they need to survive, even when snow blankets the ground.

Where Are the Robins in Winter?

If robins are around during the colder months, why don’t we see them as often? The answer lies in their behaviour. In winter, robins tend to form flocks and stay in wooded areas where they can find shelter and food. They’re much quieter during this time, conserving energy and staying out of sight.

As winter begins to wane and food sources in the woods become scarce, robins start venturing out into open spaces, such as your backyard, in search of food. This behaviour often coincides with late winter and early spring, leading many to believe they’re returning from migration when, in fact, they’ve been nearby all along.

What Do Robins Eat in Winter?

During the winter, robins shift their diet from insects and worms to fruit. They feast on berries from trees like mountain ash, sumac, and crabapple. If you’d like to support robins in your area during the colder months, consider planting native fruit-bearing trees and shrubs or offering dried fruit in your feeders.

Be mindful of ice storms or snowstorms that cover thawed ground that Robins may have been harvesting insects from. Their food sources become covered and they may need assistance for survival. Robin suet at ground level,  and fruit and/or mealworms in an open style feeder may be helpful during these weather events. Apples, cranberries, raisins are good options for Robins. Do not use grapes or raisins in yards that dogs have access to, as they are toxic to dogs.

Spotting Robins in Late Winter

If you catch sight of a robin in late February or March (even January some years), it doesn’t necessarily mean spring is here. Instead, it’s a sign that these resourceful birds are leaving their wooded winter hideouts to search for available food sources in more open areas.

So, the next time you see a robin in the snow, remember: these birds are tougher than they look. Their presence isn’t a promise of spring but a testament to their adaptability and resilience. Maybe spring isn't just around the corner, but the good news is, regardless, spring is on it's way.
