Fort Washington in Montgomery County, Pennsylvania — The American Northeast (Mid-Atlantic)
On the Wing
In North America, migrating raptors travel along several migratory routes. This hawk watch site sits along the eastern-most route, known as the Atlantic Coastal Flyway. Birds fly south for the winter from northeastern Canada and the United States, following the Appalachian mountains and the Atlantic coastline as far south as Argentina. Each species migrates on its own schedule; years of hawk-watching have shown which times are best for spotting each species.
To travel the longest distance using the least amount of energy, birds take advantage of thermals. Raptors spiral high into the air in these rising columns of hot air and then use that height to glide until they can catch another thermal.
Surfing on the Mountain
Another way birds use air currents to their advantage is by slope surfing or slope soaring. When winds from the north and west blow up against the Appalachian mountain chain, the wind is deflected up. That creates a wave of air that birds surf for long distances, using very little energy.
Be a Raptor Ranger
Launch your own “hawk” migration at home. Create paper airplanes and see which one travels farthest. Do different types of wings and tails work better than others? Can your plane catch a breeze to surf farther?
