Correction to: Nature Communications https://doi.org/10.1038/s41467-024-46052-x, published online 23 February 2024

The original version of this Article contained an error in the third sentence of the third paragraph of the Results, which incorrectly read “We annotated 414 protein-coding genes on the sexually differentiated region (SDR) of chromosome W, making it the most gene-rich SDR of bird W chromosomes, suggesting that only 54.6% of the original gene content was lost from the W chromosome, in contrast to the greater that 90% found in most land birds.”. The correct version states “We annotated 414 protein-coding genes on the sexually differentiated region (SDR) of chromosome W, making it the most gene-rich SDR of bird W chromosomes. After removing genes that replicated independently on the W chromosome, 83.4% of the original gene content was lost from the W chromosome, in contrast to the greater than 90% found in most land birds”.

This has been corrected in both the PDF and HTML versions of the Article.
