Nest Sites in Buildings

When you think about it where does a swift nest? They could be in the eaves of a building, in the stone work, on the attic floor or on top of the walls. We have seen them in small sites about the size of a child's ball and in over flow pipes. Here are some examples of nest sites in or around buildings
