Description
Little Terns Sterna albifrons breed in Japan as far north as the Tohoku Region of Honshu. The tern's natural breeding habitat was coastal beaches and wide river gravels, but most of these habitats have been eliminated by landfill and river impoundment project. Newly reclaimed areas, especially in urbanized regions, have been serving as breeding grounds, but the number of little terns has decreased steadily, and the species is now listed as vulnerable species by the Japan Environment Agency (1991). Given the high value of land in coastal regions of Japan, restoring and setting aside of sufficient breeding habitats will be difficult. Artificial breeding habitats, including roof top habitats, are thus expected to play a major role in helping the Little Tern to recover in Japan.<br>This research, conducted from July 8-16, 1996, was designed to survey roof-top nesting sites provided for Least Tern Sterna antillarum and Black Skimmer Rynchops niger in the Florida Panhandle area. Research materials and on-site inspections were graciously facilitated by Jeffery Gore, and Heather Bolte, Florida Game and Fresh Water Fish Commission. The research focused on factors involved in successful use of rooftop breeding sites, such as substrate, protection from predations, etc.. The author now believes that buildings such as large warehouses found along the shores of Tokyo Bay could be covered with gravel and turned into artificial breeding habitat for Little Tern and several species of plover, which also now suffer from loss of natural breeding areas.
