Phylogenetic trees for AIVs collected globally and submitted to GISAID since January 1, 2021, inferred using ML methods. Branches shaded by AIV lineage; tips shaded by AIV subtype and location. H5N1 viruses from the 2021–2023 Western hemisphere outbreak are shaded yellow, South American H5N1 viruses (except Peru) are shaded green, and Peruvian H5N1 viruses are shaded pink. Cartoon animals denote notable outbreaks in mink in Spain, sea lions in Peru, and seals in Maine, USA. A detailed tree is provided for the PB2 segment, including bootstrap values, labels, and a box around the R6 reassortant clade that is presented in greater detail in Fig. 3A. Smaller trees are provided for the other 7 segments. Raw tree files for each genome segment are available at GitHub (https://github.com/mostmarmot/Peru_AIV/).
