Tóm tắt

Swainson?s hawk migration can be best described in terms of conditions that support soaring flight, rather than any kind of habitat selection. These birds fly a relatively straight path to make their migration as short as possible, but are constrained by the landscape available to them between their breeding and wintering grounds.
