American Robin’s are not fussy about their nest site. So many customers tell me the same thing “They nest over the porch light.” Usually it is under the protection of a porch roof or an eave. This serves as protection from their largest preditor, the Hawk. The Robin will nest on a narrow window sill so their nest boxes don’t have to be elaborate. A shelf 6″ wide and 8″ long with a little roof. You can hang them on the back side of a shed or even a house. Just don’t put them out in full view of passing hawks or as soon as the eggs hatch they will be picked off one by one. Keep them protected.
