Dataset of a social foraging experiment with naive and specialist house sparrows For questions or comments, please contact Naama Aljadeff (naama.aljadeff@gmail.com) -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- File: Stage2_specialists Description: Choices of specialized individuals Column heading Description Sparrow Sparrow identity Cohort Experimental cohort (1-6). Cohorts are replications of the experiment. Group The group to which it belongs(color specialist group, shape specialist group,mixed specialist group= with color and shape specialists) Specialization The type of specialization on which it was trained (color or shape) Session Experimental session (1-4). Sessions are sequential social foraging periods on a grid with replenished food reward. RC The number of choices for the rewarding color in intact wells (reward was initially available with a probability of 0.5,Intact wells are ones that had not been already pecked by any of the sparrows, including the focal bird) RS The number of choices for the rewarding shape in intact wells (reward was initially available with a probability of 0.5,Intact wells are ones that had not been already pecked by any of the sparrows, including the focal bird) R cues The number of choices for one of the rewarding cues (color or shape) in intact wells. Prop RC The proportion of choices for the rewarding color out of the total number of choices for the rewarding cues. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- File: Stage2_naive Description: Choices of naive individuals Column heading Description Sparrow Sparrow identity Cohort Experimental cohort (1-6). Cohorts are replications of the experiment. Group The group to which a naive sparrow was introduced (color specialist group, shape specialist group,mixed specialist group= with color and shape specialists) Session Experimental session (1-4). Sessions are sequential social foraging periods on a grid with replenished food reward. RC The number of choices for the rewarding color in intact wells (reward was initially available with a probability of 0.5,Intact wells are ones that had not been already pecked by any of the sparrows, including the focal bird) NRC The number of choices for the non rewarding color in intact wells RS The number of choices for the rewarding shape in intact wells (reward was initially available with a probability of 0.5,Intact wells are ones that had not been already pecked by any of the sparrows, including the focal bird) NRS The number of choices for the non rewarding shape in intact wells R cues The number of choices for one of the rewarding cues (color or shape) in intact wells. RC exp The expected number of choices for the rewarding color at random, given the number of available intact wells of this cue RC obs/exp The observed to expected ratio for the rewarding color NRC exp The expected number of choices for the non rewarding color at random, given the number of available intact wells of this cue NRC obs/exp The observed to expected ratio for the non rewarding color RS exp The expected number of choices for the rewarding shape at random, given the number of available intact wells of this cue RS obs/exp The observed to expected ratio for the rewarding shape NRS exp The expected number of choices for the non rewarding shape at random, given the number of available intact wells of this cue NRS obs/exp The observed to expected ratio for the non rewarding shape ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- File: Stage2_success analysis Description: The level of success experienced by the specialized individuals Column heading Description Sparrow Sparrow identity Cohort Experimental cohort (1-6). Cohorts are replications of the experiment. Group The group to which a speciallist sparrow belongs or to which a naive sparrow was introduced Specialization The type of specialization on which a specialist sparrow was trained (color or shape) or "naive" for naive individuals. Session Experimental session (1-4). Sessions are sequential social foraging periods on a grid with replenished food reward. Success in The type of cue for which success level was estimated Successful pecks The number of successful pecks (pecks in intact rewarding cue wells containing food) Unsuccessful pecks The number of unsuccessful pecks (pecks in open wells or in rewarding cue wells without food) Sum The total number of pecks Prop success the proportion of successful pecks out of the total number of pecks in that cue (including open wells that were already empty). ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- File: Stage3 Description: The level of success experienced by the specialized individuals Column heading Description Sparrow Sparrow identity Cohort Experimental cohort (1-6). Cohorts are replications of the experiment. Group The group to which it belongs(color specialist group, shape specialist group,mixed specialist group= with color and shape specialists) Session Experimental session (1-4). Sessions are sequential social foraging periods on a grid with replenished food reward. RC The number of choices for the rewarding color in intact wells (reward was initially available with a probability of 0.5,Intact wells are ones that had not been already pecked by any of the sparrows, including the focal bird) NRC The number of choices for the non rewarding color in intact wells RS The number of choices for the rewarding shape in intact wells (reward was initially available with a probability of 0.5,Intact wells are ones that had not been already pecked by any of the sparrows, including the focal bird) NRS The number of choices for the non rewarding shape in intact wells R cues The number of choices for one of the rewarding cues (color or shape) in intact wells. Successful pecks The number of successful pecks (pecks in intact rewarding cue wells containing food) Unsuccessful pecks The number of unsuccessful pecks (pecks in open wells or in rewarding cue wells without food)
