Title Sperm competition experimental data
Downloaded 23 times
Description The file contains the data collected during a sperm competition experiment conducted on captive bred zebra finches. Using a mate switching experimental design, we investigated whether sperm length (either long or short) influenced the number of sperm from each competing male that reached the ovum, and the number of embryos sired by each male.

Title Summary paternity
Downloaded 11 times
Description The file contains the summary paternity data for each individual trio of birds (one female and one pair of males) used in the sperm competition experiment. This file was required to calculate summary statistics for the manuscript.

Title Sperm quality comparison sperm competiton males
Downloaded 12 times
Description This data file contains the results of the sperm quality analyses carried out on all male zebra finches that were used in the sperm competition experiments. Data are arranged side by side for each pair of competing males, and analysed by comparing the sperm quality long and short sperm males, using a paired design.

Title Copulation rate
Downloaded 9 times
Description This file contains the data from a study investigating whether male zebra finches with different sperm lengths (long or short) copulated with females at the same rate. These males were not used in the sperm competition experiments.

Title Sperm quality comparisons
Downloaded 14 times
Description This R script contains the code to investigate whether sperm quality varies with sperm length (long or short), and whether left testes mass is related to sperm length. Code is also provided for additional studies investigating whether sperm length is related to seminal glomera mass and copulation rate (not that these final two studies did not use the males from the sperm competition experiments. The results of all statistical tests were used to make tables S1 - S4 in electronic supplementary material 2.
