Genotypes

Excel file with three sheets for the three years of this study (2013, 2014 and 2015), containing the genotypes of all individuals. The columns are as follows: individual ID, nest number (0 if not associated with a nest), age (f = adult female, m = adult male, u = chick), sample number, and then the two alleles for each marker

Sperm measurements

Excel file with three sheets. First sheet contains measurements of sperm head, midpiece, tail and total length for each individual sperm cell for each male, identified by journal number or accession number. Second sheet contains averages of sperm morphology measurements per male, with corresponding journal number, accession number, band number and sample number. The third sheet contains sperm motility measurements, as well as body morphology for each male

Sample information.

<p>Clade assignment of common ravens from North America to either California or Holarctic lineages are given for mitogenomes presented in this study and either mtDNA control region or COI sequenced in previous studies ([<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0187316#pone.0187316.ref017" target="_blank">17</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0187316#pone.0187316.ref018" target="_blank">18</a>]; authors’ unpubl. data).</p

Graphical overview of the <i>Corvus corax</i> mitogenome.

<p>The figure contains the following information, from the outermost to the innermost layer: (1) Gene products for annotated genes. (2) Genome position, minor ticks for every kb. Red bars illustrate GC-content in 20 bp windows. (3) Forward and (4) reverse genes. Blue colours show tRNAs, red colours show rRNAs and grey colours illustrate protein coding genes. (5) Coverage plot with log transformed coverage. (6) Position for amplicon 1 and (7) position for amplicon 2. The figure was created from GenBank accession KX245135 in the software Circleator [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0187316#pone.0187316.ref042" target="_blank">42</a>].</p
