Journey North American Robin Robin Territory Study Background A robin out there someplace calls your backyard its home territory. A robin's territory, the place where mating and nesting occurs, is usually less than half an acre.
Territories often overlap, perhaps because of the feeding grounds that neighboring robins share.
Another pair nested next door on one side. Yet another nested next door on the other side. A pair of robins also nested in the yard behind hers. After a few territorial squabbles, all the robins pretty much kept to their own yards for feeding. But this woman had the only birdbath on the block, so two of the neighboring pairs of robins started sneaking into her yard for drinks and baths.
