Where Swifts Nest
Swifts On The Nest - Photo David Callan
Swifts are usually to be found nesting under roof tiles, just inside the roof space of a building or in holes in a wall.
Wherever there is a local colony and holes in the eaves or broken pointing, or missing tiles, they will eventually find suitable holes and move in. Anyone who has watched a pair of swifts looking for a suitable "home" will know how thoroughly and persistently they will investigate anything that looks like a possible site.
It is not the case that they only nest in old buildings. There are swifts nesting in houses built in the 1960s/70s.
They will generally be found to be nesting over 3m above ground level, though like all our other generalisations that one is not infallible.
All swifts which are seen going into a site are not necessarily nesting, as young non-breeding birds roost at nest sites - but that is an added complication that does not need to make any difference to swift nest site conservation - a roost site is a potential nest site.

In Holes in Walls
These tend to be in older stone buildings, where pointing has crumbled to leave small holes
