Saber-toothed cats and other predators went extinct as well, as did many kinds of vultures, including Teratornis Merriam--the largest flighted bird ever, with a wingspan of 3 meters or more.
Firing such fast projectiles into material is a technique engineers use regularly to see how jet engine components stand up to a mid-flight bird-strike.
Because the refuge is a stopover on the migratory flight corridor, bird life is dynamic and ever changing.
In flight, this bird has powerful, shallow, and flexible wing beats.
In flight, the bird's two black and white bands on the primaries and secondaries are conspicuous.
During the northern lapwing's zigzagging display flight, the bird's outer primaries produce a humming sound.
The flight of 'Bird' from humble call for deliverance into a frenzied ecclesiastic hymn is utterly spine-tingling.
