Abstract The ability of viruses to emerge in new species is influenced by aspects host biology and ecology, with some taxa harbouring a high diversity abundance viruses.

Through total RNA sequencing 18 bird species, identified 50 9 families, which 96% were novel. Of note, passerines (perching birds) exhibited diversity, found across all nine families identified.

Overall, results highlight importance understudied island ecosystems as refugia well intricate interplay between ecology behaviour shaping communities.

Highly pathogenic avian influenza (HPAI) virus subtype H5N1 has never been detected in New Zealand. The potential impact of this on Zealand's wild birds would be catastrophic. To expand our knowledge viruses across Zealand, we sampled aquatic from its outer islands and subantarctic territories. Metatranscriptomic analysis 700 individuals spanning 33 species revealed no detection during the annual 2023-2024 migration. A single H1N9 red knots (Calidris canutus) was noted. This study provides a baseline for expanding monitoring
