In September 2008, a newly dead Gray's Grasshopper Warbler Locustella fasciolata was found on a ferry sailing from Kyushu to Amami-Oshima Island, Japan. The bird was a first-year male in good physical condition, and is considered to have arrived on the ferry during that journey, although the exact time and location of arrival was not confirmed. The cause of the death was inferred to be a collision with the ferry, an event not influenced by bad weather. It is widely believed that a large number of birds are killed at sea during migration. The collation and study of information on dead birds found on ships might contribute towards an understanding of migration in these species.
