Rossitten Bird Observatory

The Rossitten Bird Observatory (Vogelwarte Rossitten in German) was the world's first ornithological observatory. It was sited at Rossitten, East Prussia (now Rybachy, Kaliningrad Oblast, Russia), on the Curonian Spit on the south-eastern coast of the Baltic Sea. It was established by German ornithologist Johannes Thienemann and operated until 1944. In 1945 East Prussia was divided between Poland, Russia and Lithuania, and most ethnic Germans expelled.

The 98 km long Curonian Spit is a thin sand peninsula, ranging from about 400 m to 4 km in width, that separates the Baltic Sea from the shallow Curonian Lagoon. It has several settlements along its length. It lies on a major migration route for birds following the coastline of the eastern Baltic. Thienemann first visited the fishing village of Rossitten there in 1896 where he experienced “a bird migration proceeding in a regular manner but more massive than had ever before been observed in Germany” and he “could not stop wondering whether something of permanent value might somehow be achieved here”.

At the German Ornithological Society’s 50th anniversary celebration in Leipzig in 1900 he gave a lecture that persuaded the Society to establish a bird observatory at Rossitten, as a cooperative project with the Prussian Government. Thienemann was given the job of setting it up, something accomplished when it opened on New Year's Day 1901, as well as serving as the founding director.

The observatory operated under the auspices of the German Ornithological Society until 1923. From then until its dissolution in 1946 the observatory came under the management of the Kaiser Wilhelm Society, giving it a solid institutional framework. Its constitution was ambitious and broad, including nine main areas of bird research: migration, behaviour, moult, economic value, protection, the establishment of a bird collection, the procurement of research material for scientific state institutes, the expansion of research relevance to other kinds of animals, and public education.
