The main file provided below (S1 Data) contains a global dataset of estimated sexual selection scores and accompanying uncertainty estimated for all the world’s birds in two different taxonomic treatments: BirdTree (Jetz et al. 2012) and eBird (Clements/eBird taxonomy). The structure and nomenclature of these data sheets follows AVONET (Tobias et al. 2022) so that sexual selection data presented here can be directly integrated with all morphological, ecological and geographical data presented in AVONET:
Tobias et al. (2022). AVONET: morphological, ecological and geographical data for all birds. Ecology Letters doi: https://doi.org/10.111/ele.13898). Figshare dataset: https://doi.org/10.6084/m9.figshare.16586228.v7

S1 Data. Species level sexual selection information for the world’s birds.
Sheet 1 in S1 Data. Metadata. Definitions and sources for all variables in subsequent data sheets. Sheet 2 in S1 Data. Sexual selection scores (BirdTree). Sexual selection scores and associated uncertainty estimates and source citations for 9988 bird species included in the BirdTree dataset (Jetz et al. 2012), along with corresponding taxonomic, ecological, morphological and distributional data, where available (n = 9836 species). Sheet 3 in S1 Data. Sexual selection scores (eBird). Sexual selection scores aligned with an updated Clements taxonomy used in major online resources, including eBird and Birds of the World (n = 10671 species). Sheet 4 in S1 Data. Sexual selection metrics. Measured residual testes mass, Bateman gradients (βSS), and Opportunity for Sexual Selection (IS) values used in sensitivity analysis. Sheet 5 in S1 Data. Taxonomic crosswalk. Guide to species matching for users transferring data between BirdTree and eBird taxonomies, which often differ in spelling and treatment of allospecies. Sheet 6 in S1 Data. Data sources. Full references for sources cited in Sheet 2.
S2 Data. Data used in figures showing family-level or species-level averages.
Sheet 1 in S2 Data. Mean sexual selection scores for bird families partitioned by trophic level, as shown in Fig 5B. Sheet 2 in S2 Data. Mean sexual selection scores for bird families, partitioned by migratory behaviour, as shown in Fig 5C. Sheet 3 in S2 Data. Mean sexual selection scores for bird families, partitioned by territorial behaviour, as shown in Fig 5D. Sheet 4 in S2 Data. Mean sexual selection scores and temperature seasonality for avian families, as shown in Fig 5E. Sheet 5 in S2 Data. Extracted model predictions from species-level phylogenetic models predicting sexual selection score according to univariate life history traits. Values correspond to model predictions overlaying family averages in Fig 5B-E. Sheet 6 in S2 Data. Mean sexual selection scores for each data certainty partition, as shown in S2A Fig. Sheet 7 in S2 Data. Mean sexual selection scores for different ecological groups at each five-degree latitudinal bin, as shown in S7 Fig.
SAR_rasters.Rdata. Derived global rasters of avian sexual selection, averaged for all occurring species at 200km resolution. These rasters are used to run SAR models.
wgs84_rasters.Rdata. Derived global rasters of avian sexual selection, averaged for all occurring species at 5km resolution. These rasters are used to produce figures.
