Does anyone know what "Kun" appeared in China's ancient books besides Shan Hai Jing?

This?

This is from Japan

Guns, birds mentioned in ancient books, look like pheasants.

Guang Yun: Thank you for the sheep. Thank you for the rhyme. It's a sound night. Bird name. Like a pheasant

Shan Hai Jing: There are birds on a single mountain, such as pheasants, prefixes, white wings and yellow feet, which are called white bream, and it hurts to eat them.

Most animals can be found in Shan Hai Jing.
