The tricolored blackbird, Agelaius tricolor, is a gregarious species that forms enormous breeding and foraging colonies in wetland and agricultural habitats, primarily in California, USA. Once extremely abundant, species numbers have declined dramatically in the past century, largely due to losses of breeding and foraging habitats. Tricolored blackbirds are currently listed as Endangered by the IUCN, and Threatened under the California Endangered Species Act. Increased genetic information is needed to detail the evolutionary consequences of a species-wide bottleneck and inform conservation management. Here, we present a contiguous tricolored blackbird reference genome, assembled with PacBio HiFi long reads and Dovetail Omni-C data to generate a scaffold-level assembly containing multiple chromosome-length scaffolds. This genome adds a valuable resource for important evolutionary and conservation research on tricolored blackbirds and related species.
三色黑鸟，Agelaius tricolor，是一种群居物种，在美国加利福尼亚州的湿地和农业生境中形成了巨大的繁殖和觅食群体。曾经极为丰富，但在过去一个世纪中，其数量急剧下降，主要是由于繁殖和觅食栖息地的丧失。三色黑鸟目前被 IUCN 列为濒危物种，根据加利福尼亚濒危物种法案被列为濒危物种。需要增加遗传信息来详细说明全物种瓶颈的进化后果，并为保护管理提供信息。在这里，我们展示了一个连续的三色黑鸟参考基因组，该基因组使用 PacBio HiFi 长读和 Dovetail Omni-C 数据组装而成，生成了一个具有多个染色体长度支架的支架水平组装。这个基因组为三色黑鸟和相关物种的重要进化和保护研究提供了宝贵的资源。
