<p>Chimney swifts feed exclusively while in flight. They are primarily insectivores (Palmer and Fowler, 1975). They forage by hovering over tree branches and catching insects in flight; they take a variety of insect and spider prey. Forty to fifty chimney swifts were recorded hovering at the outer branches or diving through the top branches of a sweetgum tree in pursuit of a particular species of weevil (Chantler and Driessen, 2000).<span> (Chantler and Driessens, 2000; Palmer and Fowler, 1975)</span></p> <p><strong>Animal Foods: </strong>Insects; Terrestrial Non-insect Arthropods</p>
