Take-off is one of the most energetically demanding aspects of flight, as the bird must generate enough airflow across the wing to create lift. Small birds do this with a simple upward jump. However, this technique does not work for larger birds, such as albatrosses and swans, which instead must take a running start to generate sufficient ...
In a delta formation, the trailing object follows closely behind and slightly above the lead. This allows the upwash from the lead to generate lift for the trailing object in flight. [1] [2] When using the excess lift from the lead the trailing object does not need to generate as much lift, leading to the increased efficiency. This can be used ...
Lift is a meteorological phenomenon used as an energy source by soaring aircraft and soaring birds. The most common human application of lift is in sport and recreation. The three air sports that use soaring flight are: gliding, hang gliding and paragliding. Energy can be gained by using rising air from four sources: Thermals (where air rises ...
Birds use wing-assisted inclined running from the day they hatch to increase locomotion. This can also be said for birds or feathered theropods whose wing muscles cannot generate enough force to fly, and shows how this behavior could have evolved to help these theropods then eventually led to flight.

For birds and flying mammals, geolocators often take the form of a little solar-powered harness, which is fitted to the back of the animal and can weigh as little as half a gram.
How do birds get their colors? Understanding bird coloration combines biology and physics. There are two primary ways that birds get their color: pigmentation and the physical structure of the ...
Take deer and birds, for example. Deer let birds land on them and pick through A large animal like a buffalo allows smaller animals like birds to pick through their fur while remaining unbothered.
Wieselsberger (1914): An aerodynamicist who was the first to suggest that a formation may give birds an aerodynamic advantage. From the principles of aerodynamics, he knew that birds generate Bernoulli lift because of the upwash and downwash at the edges of their wings. He proposed that birds flying in a V formation make use of the upwash of ...
