 A sparrow sized raptor had an extrodinary stride length indicating that it may have glided between steps.  Maybe like a flying fish on land.

The Cursorial theory on the origins of powered flight in birds
always made a great deal more sense than the Arboreal.
Amongst the obvious facts is that birds are so well adapted to
the ground that flightless birds -- secondarily flightless --
began evolving relatively quickly!
Not the only piece of evidence but amongst the more obvious...
