This study site is in the Gulf of Alaska and has been run by Scott Hatch (Institute for Seabird Research and Conservation) intermittently since the 1970s. In 1995, Scott adapted a design originally pioneered by John Coulson in England to fit an abandoned radar tower with ledges and one-way glass. Each year since then, a subset of birds have been supplementally fed capelin, and their reproductive success monitored. The site is a globally unique laboratory where individual wild black-legged kittiwakes have been monitored for two decades and can be studied in close proximity. For many individuals, we know their date of birth, their date of death, their partners, the date they started breeding each year, how many offspring they produced each year, and how fast their offspring grew. Apart from the kittiwakes, a couple of dozen pairs of pelagic cormorants nest on the towers and can be studied via the same one-way glass windows. Tufted puffins, rhinoceros auklets, common murres, tree swallows, glaucous-winged gulls and a number of other species also occur on the island, and are studied in varying degrees of depth. A photo album from various visits to Middleton is available here. Both Tim Van Nus (here) and Mike Johns (here) have blogged about their experiences on the island.
