With a specific name like Turdus migratorius, you might thing the American robin is only here part of the year. After all, migratorius implies it migrates. Well, it does. Nevertheless, for the overwhelming part of the 48 contiguous states, the robin is a year-round fixture. Their summer breeding grounds extend from the southern states (and include the mountains of central Mexico) to cover all but the most arctic portions of Canada. In the winter they move south, with their northern limit right around the U.S.-Canadian border. So, if you live in Canada, their arrival is a sure sign of spring. The birds we see in the summer may not be the birds we see in the winter but frankly, they all look pretty much alike. We often see them eating berries on the holly in our front yard. This time of year, as it begins to warm up, they are active pulling up worms, as this one was doing before being so rudely interrupted by me.
