These birds are not strongly migratory, but they will leave the coldest parts of their range in winter and make altitudinal movements.

Swallow nests are generally built with plaster, wood, terracotta or stucco. Artificial nests, such as nest boxes, are an important conservation tool for many species, however nest box programmes rarely compare their effectiveness with individuals not using nest boxes. Red-footed falcons using nest boxes in heavily managed landscapes produced fewer fledglings than those nesting in natural nests, but also than pairs nesting in nest boxes in more natural habitats.
