I wouldn't be surprised if other birds do this too.
"Using satellite tracking to study the paths pigeons take on homeward-bound
journeys, researchers have obtained strong new evidence to support a
long-held theory: in some environments, pigeons instinctively learn to
follow major roadways in navigating their flight."

This phenomenon was noted, and discussed, in the magazine 'British
Birds' some years ago. I don't have the references to hand, but will
search for them ( if a certain biologist doesn't get in first).
As far as I can remember, other species *were* implicated.
