  "account": "In recent years, the field of avian genomics has experienced rapid growth, vastly increasing our understanding of genome evolution. However, it is crucial to evaluate how bird genomes are sampled across the tree of life and their geographic distributions to fully grasp their impact on global bird diversity and diversification patterns. A study evaluated all existing avian genome assemblies based on geography, taxonomy, conservation status, and time. The research found that only about 15% of recognized avian species have at least one genome assembly, indicating substantial gaps in our knowledge. Although all orders of birds were represented, 24 bird families, all of which are native to the Global South, had no genome assemblies at all. Additionally, only around 37% of recognized bird genera, or roughly 2,397 species, had their genomes represented in the database.\n\nAlarmingly, nearly 78% of the most evolutionarily distinct and globally endangered (EDGE) bird lineages lacked a genome. This suggests that the genomic resources are heavily concentrated in temperate regions of the Global North, while species-rich tropical regions in Africa, South America, and Southeast Asia remain severely underrepresented. Even after considering factors such as conservation status, evolutionary distinctiveness, and ecology, bird species from the Global South had approximately four times lower odds of having a genome compared to their counterparts from the Global North. Notably, the surge in genome sequencing post-2021 unintentionally widened this existing gap.\n\nThe findings of this study underscore the persistent disparities in genomic resources across the Global South and emphasize the urgent need for collaborative efforts to address these global knowledge gaps.",
