Texas Hawks in Flight|
Shape Recognition Training
This presentation was developed by Rob Fergus in response to his students in a recent class he taught at Hornsby Bend on identifying hawks as you see them in migration (way up in the sky, backlit, etc.). Subtle differences in silhouettes are addressed, as well as pattern/plumage and other characteristics of raptors in flight.
