Proceedings of the Royal Society B 284: 20170272 The document "Caves et al Egg Phenotypic Measures.csv" contains egg phenotype data for all clutches, including one-egg clutches, that were considered in this manuscript. Data for all Columns: -Set Mark: Unique identifier for each egg; in the original egg collection, every clutch was assigned a set mark. -Egg.No: an identifier for the number of the egg in a given clutch -Family: Warbler or Weaver -Species: Species name; parasites are identified by Species name of the parasite_host species name -Status: Whether a species was classified as "parasitised" or "unparasitised" in the Choma Region of Zambia. Warblers are parasitised by the Cuckoo finch (Anomalospiza imberbis); weavers are parasitised by the Diedrik Cuckoo (Chrysococcyx caprius). -Proportion Energy: The relative contribution of the main marking; how important the main marking is to overall pattern -Total Power: A measure of the contrast between egg pattern markings and background colour -Marking Filter Size: The filter size that captured the most pattern information; the predominant marking size -Proportion Coverage: The proportion of the egg that is covered with markings -Dispersion: The difference in proportion coverage between the narrow and wide regions of the egg; how dispersed across the egg markings are - Luminance: photon catch for double cones, modelled through blue tit (Cyanistes caeruleus) visual system - S_UV: standardized photon catch for ultraviolet cone, modelled through blue tit (Cyanistes caeruleus) visual system - S_SW: standardized photon catch for shortwave cone, modelled through blue tit (Cyanistes caeruleus) visual system - S_MW: standardized photon catch for mediumwave cone, modelled through blue tit (Cyanistes caeruleus) visual system, modelled through blue tit (Cyanistes caeruleus) visual system - S_LW: standardized photon catch for longwave cone, modelled through blue tit (Cyanistes caeruleus) visual system The document "Caves et al_Consistency and Distinctiveness.csv" contains measures of consistency and combinatorial and absolute distinctiveness for each species Data for all Columns: -Column 1: Species name -Parasitism_Choma: Parasitism status (parasitized or unparasitised) in our study area -Parasitism_Africa: Parasitism status elsewhere in Africa -P_designation_for_graph: A categorical variable used to generate Figure 3 -Family: warbler or weaver -n: sample size of clutches used in analysis -Absolute distinctiveness: a measure of absolute distinctiveness, the variance component of Entropy, also known as Hvar -Combinatorial_distinctiveness: a measure of combinatorial distinctiveness, the correlation component of Entropy, also known as Hcor -MDPS_distinctiveness: mean distinctiveness measured using multi-dimensional phenotypic space analysis -MDPS_distinctiveness_sd: because MDPS distinctiveness takes the mean of the distinctiveness of each clutch, the standard deviation is given in this column -Consistency: mean phenotypic consistency in a species -Consistency_sd: because phenotypic consistency was taken as the mean consistency of clutches across a species, the standard deviation is given here The next four columns give MDPS_distinctiveness and consistency values re-calculated in several different ways (see main text for details): -Resampled: analyses performed only 5 randomly sampled clutches from each species -Permuted: calculated using egg phenotypic traits randomly permuted across individuals -10iter: calculated by randomly resampling one egg over 10 iterations to calculate distinctiveness -BirdTree_Spp Name: the scientific name given on BirdTree.org, for use in phylogenetic analysis -Species: species name, this column is included for the R code to run The document "Caves et al_Consistency by clutch.csv" contains clutch-level measures of consistency. -Set Mark: Unique identifier for each egg; in the original egg collection, every clutch was assigned a set mark. -Species: species name -Parasitism: Parasitism status (parasitized or unparasitised) in our study area (Choma) -Family: warbler or weaver -Clutch_consistency: phenotypic consistency in a given clutch The file "BirdTree_output.nex" contains 100 resolved phylogenies for our species of interest, generated by BirdTree.org
