Robins are one of those birds that are practically ubiquitous. They nest all the way from the Arctic tundra throughout most of the United States, particularly the northern tier of states and central part of the country. But they live in all manner of habitats. They are a bird that is very familiar, almost domestic in terms of their ability to nest right near people's houses and so forth, even in cities. If there's a little park, there'll be robins there. But they also can nest in the woodlands and their demeanor changes. If you are looking at robins that are not so habituated to seeing people, they can be very shy birds. And, as you get on farther north, where the forests begin to be more coniferous and spruce and fir and so forth, that kind of thing, you'll find them nesting in those habitats. And I have actually seen American robin nests on the ground in northern Alaska, right where there are no trees. So, they either have to put them on the ground or in very low shrubs. This kind of thing. So, they're very, very diverse in terms of the habitats they use and they have a very wide range. And in the winter time, if you include the winter time as well as their nesting range, you can find robins throughout North America.
