Explanation of variables

This file provides an explanation for variables used in all other data files associated with this manuscript

Untreated Males RS & Plumage

Data for male reproductive success and plumage color of untreated males

Exptl Males Before After Treatment

Data for experimental males before and after plumage treatmen

WPS vs EPS Paired Plumage

Plumage data paired for within-pair sires and the extra-pair sire(s) that cuckolded them

KRL data

Time to hemolysis for 50% of red blood cells in the KRL assay. File is tab-delimited text file with 11 variables (columns). The first row is the headers for each column and there are 39 subsequent rows of data.Variables names are:Band No Breed Experience (Experienced = known prior breeding experience; inexperienced = no known prior breeding experience on the main study area; blanks indicate unknown because the bird was captured off the main study area) Time to 50% hemolysis (the response variable) Jdate for KRL (date blood was sampled for KRL assay; 1=1 May) Tarsus (tarsus length of bird, mm) Mass (total body mass of bird, g) Mask (facial mask size of bird, mm^2) bib size (size of yellow throat patch, mm^2) Yellow brightness (see Methods) Ccar (see Methods) N replicates (number of different assays performed; see Methods

OxidativeStress & GSH data

Tab delimited file with 14 columns (variables) and 52 rows (top row contains the variable names). Variables are: Band Number (band number of individual bird [4 digit prefix and 5 digit suffix, after the decimal point]) Capture Date(1=1May) Breed Experience (see KRL file for description) Exper Group (see KRL file for description) Mask (see KRL file for description) bib size (see KRL file for description) Yellow Brightness (see KRL file for description) Ccar (see KRL file for description) Tarsus (mm) Weight pre (g, prior to bird being put in an aviary, if part of the LPS experiment) GSH pre (see Methods for GSH; "pre" refers to estimate prior to LPS experiment) ROMs/TAC_pre (see Methods; "pre" refers to estimate prior to LPS experiment) GSH post-pre (see Methods; "pre" refers to estimate prior to LPS experiment) ROMs/TAC post-pre (see Methods; "pre" refers to estimate prior to LPS experiment

MHC class IA exon 3 sequences

Data for Fig1. Genetic variation and population size

tab delimited file with data used in Figure 1. Contains Population (state code), genetic marker, alleles per locus (mean-centered), population size, log of population size, squared log of population size, alleles per locus, mean alleles per locus (for each marker) and sample size for each population
