This file contains the capture-mark-recapture data used to estimate the effects of clutch and brood size on adult female breeding probability and survival. Variables are as follows: "ch" is the capture histories, which are in an LDLD format with two secondary occasions (nesting and banding) each represented by "L", followed by non-breeding season (represented by second "D") reencounter data (0=not encountered, 1=encountered dead, 2=re-sighted alive), primary occasions are 2008-2015. Note that the first "D" in the capture history for each primary occasion is essentially a dummy variable, which are all "0". "mbha 2008:2012" indicates if a female's reproductive output was manipulated and she was captured and marked at the nest during that year; "age 2008:2015" is the z-standardized age (mean = 8.64, sd = 5.59) of a female in year t, "ageq 2008:2015" is the squared z-standardized age value for use in models with a quadratic effect of age; "emcs 2008:2015" is the z-standardized (mean = 4.22, sd = 1.87) final manipulated clutch size value in year t; "emcsq" is the squared z-standardized emcs value for use in models with a quadratic effect of emcs; "gln" is the z-standardized (mean = 3.49, sd = 1.73) initial brood size value for the female in year t; "glnq" is the squared z-standardized gln value for use in models with a quadratic effect of brood size; and "grp" is a grouping variable that indicates that all females were manipulated during our study. Note that for variables "emcs" and "gln" the years 2013-2015 have values that are all 0 but are needed because program Mark requires time varying covariates for each primary occasion. Zeros for other variables mean the female had not yet been captured and released or was not manipulated that year.
