What does ethological mean?
Ethological is an adjective describing anything related to ethology, the branch of zoology concerned with studying animal behaviour — particularly instinctive and evolutionarily shaped behaviours observed in natural conditions rather than in artificial laboratory settings. The word appears most often in academic and scientific writing: researchers speak of ethological studies, ethological evidence, or an ethological approach when analysing how animals actually behave in the wild. It is closely associated with figures such as Konrad Lorenz and Niko Tinbergen, whose mid-twentieth-century fieldwork on imprinting, fixed action patterns, and signalling helped establish behavioural observation as rigorous science. Because it derives from the same Greek root as 'ethics', the word occasionally causes confusion with 'ethical', though its meaning is entirely descriptive rather than moral. For readers of nature writing or popular science, recognising this term signals that a discussion is grounded in systematic observation of living animals rather than anecdote or speculation.

"Her ethological research on imprinting in greylag geese transformed our understanding of attachment."
"The documentary drew on decades of ethological fieldwork among wild chimpanzees."
"From an ethological standpoint, the peacock's extravagant tail is a textbook case of sexual selection."
Konrad Lorenz's ethological work with geese that imprinted on him as 'mother' won a Nobel Prize — and proved baby animals don't need to learn who to love, they just do.

Etymology of ethological
Ethological derives from ethology, a term coined in the nineteenth century from Greek ēthos, meaning 'character' or 'customary behaviour'. The Greek root ēthos also gives English 'ethic' and 'ethics', making them true cognates. When biologists adopted 'ethology' for the scientific study of animal character and behaviour, 'ethological' followed as its adjective form, becoming firmly established through the rise of modern ethology in the twentieth century.

How ethological is actually used
A technical term used chiefly in zoology, psychology, and behavioural science. It carries a scholarly, formal register and is rarely encountered in everyday speech. In American texts both 'behavioural'-style spellings are irrelevant here since the word itself is spelled identically in British and US English.
Easily confused with ethological
Ecological relates to organisms' relationships with their environment, while ethological relates specifically to the study of animal behaviour.
Ethical concerns moral principles; despite the shared Greek root, ethological refers to the scientific study of animal behaviour.
