Original Note:
Birds have Z/W sex chromosomes https://en.wikipedia.org/wiki/ZW_sex-determination_system https://pubmed.ncbi.nlm.nih.gov/9354761/ and numbered autosomes https://en.wikipedia.org/wiki/Autosome https://www.genome.gov/genetics-glossary/Autosome In these birds, some males and some females have a difference on an autosome, Chromosome 2. https://www.cell.com/current-biology/fulltext/S0960-9822(15)01562-6 This is not a Z or W sex chromosome, but it does correspond to different complimentary parental roles in a breeding pair. https://www.audubon.org/news/the-fascinating-and-complicated-sex-lives-white-throated-sparrows
