Yes, they are. The nests are constructed in pretty much the same
configuration as I have seen on cliff faces except they are using two
exposed 2X4 beams that intersect at about a 30 degree angle and the bottom
side of the roof. The nest otherwise is "jug" shaped.

I guess that if Barn Swallows can nest on cliffs, then Cliff Swallows can
nest on barns (or houses).
Has anyone else seen such a thing?

Are they building mud nests, Scott? That's a pretty common practice
of the Cliff Swallows up here.

I just saw Cliff Swallows building nests in holes in the soffit board of
a building, a site I would have thought would only attract VG or Tree
Swallows. Don't know whether they were bringing in mud or just straw
and stuff, but they were zooming into those holes at about 40 mph.
Adaptable little buggers.
