Is it unusual to see American Robins in the middle of winter?

We do get a lot of questions from people surprised by seeing American Robins in winter. But although some American Robins do migrate, many remain in the same place year-round. Over the past 10 years, robins have been reported in January in every U.S. state, except Hawaii, (see map) and in all of the southern provinces of Canada.

As with many birds, the wintering range of American Robins is affected by weather and natural food supply, but as long as food is available, these birds are able to do well for themselves by staying up north.

One reason why they seem to disappear every winter is that their behavior changes. In winter robins form nomadic flocks, which can consist of hundreds to thousands of birds. Usually these flocks appear where there are plentiful fruits on trees and shrubs, such as crabapples, hawthorns, holly, juniper, and others.

When spring rolls around, these flocks split up. Suddenly we start seeing American Robins yanking worms out of our yards again, and it’s easy to assume they’ve “returned” from migration. But what we’re seeing is the switch from being nonterritorial in the winter time to aggressively defending a territory in advance of courting and raising chicks. This behavioral switch is quite common in birds.

You can report your robin sightings (and any other birds you see) at eBird. Read more about American Robins in our All About Birds Species guide.

    Had a flock of about 20 show up a few days ago when it was in the mid 60’s here in Raleigh, NC.

    Thanks, I’d always wondered about precisely this! Haven’t seen a winter robin in Brooklyn yet, but in spring and summer it seems we get more of them every year.

    My
    husband saw one in Woodstock, Illinois two days ago. My sister says they have Robins in Park Ridge (IL) year round. In my area – Richmond, at the Illinois/Wisconsin border – people report having bluebirds all winter long. Bluebirds and Robins are cousins.

    I hear them a lot so i know they are around but with the behavior change in the winter makes it is hard to see them.

    Go into the woods of prospect park and you will see them.

    Is the same true for other thrush like the Hermit Thrush?
