The nest of the cliff swallow is made of mud and attached to
protected areas of buildings, bridges, or other structures. It is
jug shaped, with the opening pointed downward. The swallows enter
by flying up into the opening.
One swallow is just arriving under the
eaves as another is just leaving (see the white forehead).

opening of the nest.
A rare occasion, this cliff swallow not only perched on the
wire above my yard, but waited while I went inside, got my camera and
came back out to take this picture.
