The term CAWER is a combination of two words, CROW and ER. CROW is a four-letter word that refers to a large black bird with a raucous call. ER is a two-letter suffix that is often used to denote a person who performs a certain job or activity. Therefore, CAWER can be interpreted as a person who works with crows. This could include a wildlife biologist studying CROW behavior, a falconer who uses crows to hunt, or a farmer who uses crows to scare away other birds from their crops.
