A conservation biologist is studying the problem-solving and social learning behaviours of wild kea parrots (Nestor notabilis) when presented with a novel multi-step puzzle box containing food. Currently, the researcher sits in a hide and writes a continuous, unstructured narrative describing every physical movement and vocalisation made by the keas, whilst recording their own subjective opinions about the birds' levels of "frustration" and "ingenuity".
Explain how this observational study could be improved by using structured behavioural categories.
