Wild jackdaws’ reproductive success and their offspring’s stress hormones are connected to provisioning rate and brood size, not to parental neophobia Alison L. Greggor, Karen A. Spencer, Nicola S. Clayton, Alex Thornton Explanation of column titles in raw data: BLOOD ANALYSIS.CSV Box: Nestbox for that chick Bird_BTO: Unique identifier for that individual, based on its BTO ring number Wing: Length in mm Tarsus: Length in mm Weight: Mass in grams Time_of_day: Number of minutes since sunrise when blood sampling began Mean_control: Mean entrance time of parents across both control trials Mean_test: Mean entrance time of both parents across both neophobia trials Sex: Sex of the chick Blood_time1: Number of seconds since disturbance at the nestbox began when first blood sample was taken Blood_time2: Number of seconds since disturbance at the nestbox began when second blood sample was taken Feed_rate: Mean feeding rate of parents across both control trials Colony: Nestbox colony to which the box belongs Body_condition: Condition of chick based on their residual deviation from the nestling population’s regression of weight against tarsus Num_sibs: The number of siblings each individual had in the brood at the time of blood sampling Hatch_day: Number of days from the beginning of hatching in the population that the observed box hatched Baseline: Amount of corticosterone in the first blood sample (ng/ml) Stress_induced: Amount of corticosterone in the second blood sample (ng/ml) CONSISTENCY AND FITNESS ANALYSIS.CSV Box: Nestbox for that chick Condition: Experimental condition for this observation Entrance: Time in seconds from the start of the trial Num_fledge: Number of chicks that fledged from that box Prop_fledge: Proportion of chicks that fledged out of those that hatched Mean_body_condition: Mean condition of chicks in that nest, based on their residual deviation from the nestling population’s regression of weight against tarsus Test_Order: Did the control condition precede the test condition for that test pair? (Y=1, N=2) Time: Time of day in minutes since sunrise when experiment began Days_since_hatch: Number of days since the first chick of that box hatched Colony: Nestbox colony to which the box belongs Hatch_day: Number of days from the beginning of hatching in the population that the observed box hatched Rate_1st_Control: Feeding rate calculated during the first pair of test/controls for that box Rate_2nd_Control: Feeding rate calculated during the second pair of test/controls for that box
