The flight of Birds

In order to fly, birds must counter the forces of gravity, friction and turbulence.

Through the evolution of feathers and wings along with other morphological and physiological adaptations the birds are able to fly.

Aside from your typical straight-forward flying, some birds have developed the ability to hover, fly backwards, fly upside down, and many species have the endurance to fly for several days on long-distance migrations.

It is refreshing to befriend and spend some time among the birds. The way they think and do is unknown but it is wonderful to see them take-off, fly, and land effortlessly. I was indeed inspired and tried to sketch some of them in my own inadequate way…

Learning to sketch…; any tips?
