American Robins go where there is food. Flocks can move around to different nut or fruit trees as they ripen and avoid bad weather when it blows through. I have a pond that is always flowing in my yard and they hit it occasionally throughout the winter to take baths or stop by to devour berries on a nearby mountain ash or crab apple tree.
Robins ARE territorial on their summer breeding territories, but not at their roosts, or in feeding trees. Flocking is a behavior that gives the birds more eyes and ears to search for food sources and be watchful for predators.
So the robins you saw may be flying south or to a local pond or just out foraging for a tree full of fruit. Some America Robins migrate but if you look at the range map you’ll see that there are winter populations of robins in most states year round. Robins are surprisingly hardy birds, capable of surviving temperatures well below zero. But that doesn’t mean sightings are common.
