MHC genotypes of 188 adults + 22 chicks allowing Copy Number Variation, in a table of 211 rows x 12 columns. Genotypes were determined from Illumina sequencing based on an algorithm that permits Copy Number Variation as described in Supporting Information lines 129-145. First row is header, and each remaining row corresponds to one bird. Columns are Year (year of nesting attempt: 2010 or 2013), Nest # (burrow number, unique within year but not between years), Age (Adult or Chick), Sex (determined by PCR), CWS Bird Band #, Ocle-DAB1*allele1, Ocle-DAB1*allele2, Ocle-DAB1*allele3, Ocle-DAB2*allele1, and Ocle-DAB2*allele2, Ocle-DAB2*allele3, and Ocle-DAB2*allele4
