A comprehensive reference genome assembly dataset of birds inhabiting Denmark, Greenland, and the Faroe Islands

BACKGROUND: Reference genome assemblies are essential infrastructure for investigating phylogeny, and population/conservation genetics of wild organisms. Birds serve as model vertebrates in ecology and evolutionary biology due to their well-documented natural histories and extensive community science data. FINDINGS: We release a set of 350 newly assembled avian genomes, which, when combined with 97 previously published genomes, represent 447 of the bird species recorded in Denmark, the Faroe Islands, and Greenland-the largest regional dataset of a vertebrate group to date. These genomes are published for various research activities. CONCLUSIONS: This data release advances the global effort to build comprehensive and accessible biodiversity genomic resources for the research community.
