The Red-crowned Crane Grus japonensis is an endangered species that has two separate breeding populations, one in the Amur River basin and the other in north and east Hokkaido, Japan. So far, only two (Gj1 and Gj2) and seven (Gj3-Gj9) haplotypes in D-loop of mtDNA were identified in Japan and in the continent, respectively. We obtained feathers from three cranes found in northeast Honshu. The crane in Akita in 2008, which also arrived at west Hokkaido, had a novel haplotype (Gj10). Another crane in Akita in 2009 showed a heteroplasmy (Gj7 and a novel type, Gj12). The third crane in Miyagi in 2010 also showed another type, Gj11. These results suggest that three Red-crowned Cranes appeared in Honshu and west Hokkaido were from the continent.
丹顶鹤（Grus japonensis）是一种濒危物种，有两个独立的繁殖种群，一个在阿穆尔河流域，另一个在日本北海道的北部和东部。到目前为止，在日本和大陆的线粒体DNA D-loop中分别仅鉴定出两种（Gj1和Gj2）和七种（Gj3 - Gj9）单倍型。我们从本州东北部发现的三只鹤身上获取了羽毛。2008年在秋田的那只鹤，它也到达了北海道西部，具有一种新的单倍型（Gj10）。2009年在秋田的另一只鹤表现出异质性（Gj7和一种新类型，Gj12）。2010年在宫城的第三只鹤也表现出另一种类型，Gj11。这些结果表明，出现在本州和北海道西部的三只丹顶鹤来自大陆。
