What Does This Expression Mean?

Simple Definition
The direct distance between two locations measured in a straight line.

People noticed that birds, especially crows, fly directly toward their destination instead of following human roads or paths. Since crows travel through the air, they often take the shortest route possible.
Over time, people began using this image to describe direct distance between two places.
Although crows inspired the saying, the idea applies to many birds that fly in straight paths.
