Unexplored viral diversity in Siberian cranes and wild geese: metagenomic insights from a global wintering haven.

ABSTRACT: Migratory birds are critical global carriers and vectors of various viruses, potentially driving the mutation and transmission of novel pathogens, especially zoonotic viruses. Despite advancements in sequencing technologies, the viral diversity in wintering Siberian cranes (Leucogeranus leucogeranus) and wild geese (Anser spp.) remains poorly understood. In this study, we conducted a viral metagenomic survey of fecal samples from 320 Siberian cranes and wild geese wintering in Poyang Lake, China. Through this approach, we identified 183 novel viruses associated with known and putative vertebrate-infecting viruses, including a novel coronavirus, parvoviruses, picornaviruses, picobirnaviruses, anelloviruses, and CRESS-DNA viruses. Furthermore, we detected evidence of cross-spec
