Air Quote by Lawrence Hargrave
“The closer the bird is to the surface of the water, the firmer and more inelastic is the uplift of the rising air. The bird appears to almost feel the surface with the tip of its weather wing.”
About This Quote
Source Book: Bird Flight Mechanics, 1905
Proximity to water makes rising air denser and less springy, so the bird’s wing senses the surface directly.
In simple terms: Near water, air is denser and feels solid to the wing.
Observe how environment changes lift.
