The flight patterns of two different bird species can vary greatly. For example, a hawk will soar high in the sky and swoop down to catch its prey __________ a sparrow usually stays close to the ground and flits from tree branch to branch. Hawks have large wings with long feathers that allow them to glide through the air more easily than sparrows which have shorter, rounder wings that help them maneuver quickly between obstacles. The differences in their physical features contribute significantly to how they navigate their environment while flying.
