Data set for 202 species used in the comparative analyses. The second worksheet lists the references for paternity studies. The third sheet calculates the sperm length CV and the proportion of EPY from total sperm length data. The fourth sheet gives accession numbers in the Avian Sperm Collection in the Natural History Museum in Oslo, and total sperm length for all sperm samples used in the calculation of sperm length CV, except for two species: Troglodytes aedon (Becky Cramer, pers. comm.) and Notiomystis cincta. (Helen Taylor, pers. comm.). For samples from India (Horornis fortipes, Larvivora brunnea, Passer rutilans and Phylloscopus occipitalis) accession numbers refer to digital photos, as no samples were exported. (XLSX 170 kb)
