Correction to: Nature Communications https://doi.org/10.1038/s41467-019-09971-8, published online 16 May 2019.

The original version of this Article incorrectly listed the affiliation of ‘Zhenggang Xu’ as ‘The Wildfowl & Wetlands Trust (WWT), Slimbridge, Gloucestershire GL2 7BT, UK’, instead of the correct ‘College of Life Science and Technology, Central South University of Forestry and Technology, 410004 Changsha, China’. This has been corrected in both the PDF and HTML versions of the Article.
