Figure. Migratory routes of 6 of 9 successfully satellite-tracked mallards infected with highly pathogenic avian influenza A(H5N8) clade 22.214.171.124b viruses, Ningxia, China, 2020. Mallards are indicated by different colors. The sampling site (Changshantou Reservoir) is indicated. Solid and dashed lines indicate spring migration in 2021 and autumn migration in 2020, respectively. Because the other 3 successfully satellite-tracked mallards (birds NX-169, NX-174, and NX-176) had been moving around the sampling point, their movements are not shown.
