Why it's so fast

A bird's speed depends on which kind of flight was measured. A stoop, a glide and level flapping are different jobs, and this list does not pretend they are one number.

  1. The wing is a compromise

    A wing that makes lift easily is often a wing that makes drag. Birds that dash, soar or dive are shaped for one of those jobs more than the others.

  2. Read the conditions

    Radar of a stoop, a GPS glide and a flapping mean will not agree, because the bird was not doing the same thing. The ranked figure is the one the entry names.

The dive people mean is usually the peregrine falcon.

This is how the category works. A note written for this entry appears here once it is in the database.
