Phenotypic and behavioural data from experiments

Pyrrhula pyrrhula sperm motility

Motility measures of individual sperm tracks analysed by Computer Assisted Sperm Ananlysis (CASA). The file lists the sperm tracks from 11 male Eurasian bullfinches (P. pyrrhula) with details of sampling locality and date. (Raw data file for Table 2 in the paper

Measurements of individual spermatozoa in Azores and Eurasian bullfinches

Measurements of head and flagellum length in 10 spermatozoa per male in 11 Azores bullfinches (P. murina) and 13 Eurasian bullfinches (P. pyrrhula) with details of sampling locality and date. (Raw data file for Table 1 in the paper

Tested birds

Birds were sampled in the wild in four biogeographic regions (Region): NWA - Northwest Africa, NWI - Northwest Iberia, TRC - Transcaucasia, WGC - Western Greater Caucasus. Bird ID is the unique identifier for each bird sampled. Repeated bird IDs indicate multiple infections in the same bird. Date is when the sample was taken in the field. Parasite lineage is a unique identifier and 'none' indicates that no haemosporidian parasite lineages were found. Please see the original article for details of methods

Carbon and Nitrogen Stable Isotopes of Shorebirds

Carbon and nitrogen stable isotopic signatures of shorebird toenails collected at four wintering areas: Tejo estuary (Portugal), Sidi Moussa (Morocco), Banc d'Arguin (Mauritania) and Bijagós archipelago (Guinea-Bissau
