I'm wonder if the White House 'Cliff Swallows' statement reflects the fact
that this is what they often see in Crawford, TX?  Barn Swallows
live there too, of course (see
   http://www.mbr-pwrc.usgs.gov/id/framlst/i6130id.html
).

Take a look at
   http://www.mbr-pwrc.usgs.gov/id/framlst/i6120id.html
for a picture of the Cliff Swallow's nest, range map, etc.

I'm just glad the announcement didn't call them 'Cave Swallows'! (
