These data describe individual behaviour during an experiment investigating chick responses to 3D-printed insect replicas. Data describe chick progress through an initial training period, during which they open lids of small dishes and consume mealworms, and then during a testing trial, in which they approach and open dishes on which were placed 3D-printed insect replicas. Also included are chick growth curves (daily weights in g) for the period of the experiment.

These data describe individual behaviour during an experiment investigating chick responses to different trait combinations in 3D-printed insect replicas. Replicas were based on various combinations of shape, pattern, colour and size traits taken from either non-mimetic flies (Tachina fera) or wasps (Vespula vulgaris). Data describe chick progress through several phases: - A grouped phase where chicks became familiar with foraging within the experimental arena - A training phase, during which they open lids of small dishes and consume mealworms, - A learning phase, where the chicks learned to associate fly stimuli with a reward and wasp stimuli with no reward - A testing phase, in which they were presented with single stimuli at a time and we recorded the time taken to approach and attack the stimulus. Also included are chick growth curves (daily weights in g) for the period of the experiment.

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.
