File:Table1 Treatment- binary, predator or control, used as fixed effect in both models NumberOfDisturbanceSubjects- count of number of predators observed in plot during breeding season (response variable) DisturbanceType- binary, rows with all predators used for model 1, rows with hawk predators used for model 2 PlotYear- unique number for each plot in each year (used as random effect in both models) File: Table2 PlotYearID- unique number for each plot in each year (used as random effect all models) MaleID- social father (used as random effect all models) FemaleID- social mother (used as random effect all models) BroodID - unique number for each brood EPYFemale- how many young/eggs of brood sired by male other than social father (used as response variable model 1) EPYMale- how many young/eggs the social father fathers in nests outside of this brood (used as response variable model 2) ob- unique number for each row/observation (for modeling overdispersion) MaleExplorationScore- exploration score of social father, standardized (mean centered and expressed in standard deviation units, used as fixed effect in model 2 and 4) FemaleExplorationScore- exploration score of social mother, standardized (mean centered and expressed in standard deviation units, used as fixed effect in model 1 and 3) Number of Extra-PairPartnersFemale- number of sires (fathers) of eggs in brood (used as response variable model 3) Number of Extra-Pair PartnersMale- number of partners (females) that social father has (including social mother) (used as response variable model 4) ConditionFemaleStd- social mother mass, standardized (mean centered and expressed in standard deviation units, used as fixed effect in model 1 and 3) SizeFemaleStd- social mother tarsus length, standardized (mean centered and expressed in standard deviation units, used as fixed effect in model 1 and 3) PredTreat- categorical variable, predator or control (used as fixed effect in all models) AgeFemale- age of social mother, binary: "0" = yearling, "1" = adult (used as fixed effect in model 1 and 3) ConditionMaleST- social father mass, standardized (mean centered and expressed in standard deviation units, used as fixed effect in model 2 and 4) SizeMaleStd- social father tarsus length, standardized (mean centered and expressed in standard deviation units, used as fixed effect in model 2 and 4) AgeMale- age of social father, binary: "0" = yearling, "1" = adult (used as fixed effect in model 2 and 4)
