Starlings like to catch bugs in general. They could just as well be called buggers.
TEXT OF COMIC:
Are you doing something for Mother’s Day?
Yup. I’m making cornbread for my pet starling.
Your bird isn’t a mother.
Yes he is!
A cat that catches mice is a mouser. My bird catches moths, so logically he is a mother.
Are you putting moths in the cornbread?
Whoa! BEST IDEA EVER.
