From my observations, I think that they follow the food on a yearly cycle, but, at least here in the Midwest, that movement tends to be within a given area that covers their other needs (water, shelter, and safety). For instance, at one of our best locations, we know they go down by the river in the early spring, likely looking for fish or mussels. We hear them calling down there and see the mussel shells. They then seem to spread out in the area in late spring and early summer. By late summer/autumn they seem to group in areas where they can take advantage of ripening berries and nuts (blueberries, black berries, chokecherries, acorns, and hazelnuts in our area). Once hunting season starts, we sort-of lose track of them as they seem to retreat and no longer interact with us (not that I blame them). In winter, they hole up in the deep spruce bogs, where the wind doesn't go and the bog keeps it warmer. We only know this because we see tracks leading in and out of these areas in the snow; however we only find large tracks that time of year. Presumably that is the adults out hunting for deer.
That is all based on observations, but there is a lot of supposition in there too and a lot more study needs to be done. That said, we have successfully used these observations to locate new sites where they live and figure out where they will be at various times of the year.
