Plural of ethology; multiple studies or systems of understanding animal behavior.
From Greek ēthos (character, nature) + -logia (study of) + plural -es. The plural suggests different approaches or schools of behavioral study.
Different species have wildly different ethologies—what's normal social behavior for wolves (pack hierarchy) is totally abnormal for cats (solitary hunters), and understanding this prevents misunderstanding animals.
