This dataset relates to two closely related experiments conducted using similar methodologies: one - Discrimination Ability experiment - from December 2021 to May 2022 and another - Multiple Models experiment - from October 2022 to April 2023. Data describe the responses of wild birds (mainly Great tits Parus major) towards feeding stations where insect-like stimuli concealed a possible food reward. Data include: Passive Integrated Transponder (PIT) tag records of birds visiting the feeders (note that not all birds were tagged); demographic information about the tagged birds; timings and set-up of the feeders used at each session; and which stimuli from each session were “attacked” (and in what order).

Three files describe behavioural trials involving jumping spiders, crab spiders and praying mantises respectively. They include details about the individual predators, the stimuli used and the behavioural responses from the predators.
