Why do birds pause during the upstroke?

Similar pauses or glides during the upstroke can be observed in many birds in a range of flight modes (J. M. V. Rayner & K. D. Scholey, unpublished observations), and probably contribute to dynamic control of the flight path as well as to energy economy.

What is the scientific name of the Cape pigeon?

D. capense capense south east of Tasmania The Cape petrel (Daption capense), also called the Cape pigeon, pintado petrel, or Cape fulmar, is a common seabird of the Southern Ocean from the family Procellariidae.

How does natural selection shape bird wing design?

As a consequence of high power demands, most studies of bird flight assume that the internal and external wing design in flying birds has been, and continues to be, shaped by natural selection for efficiency in flight, with efficiency defined as mechanical power output from the muscles divided by metabolic power input to the muscles.
