Ottenby bird observatory
Mörbylånga Municipality, Sweden · built 1946
Ottenby Bird Observatory (Swedish: Ottenby fågelstation) is a bird observatory in Ottenby, on the southern tip of the Swedish island Öland in the Baltic Sea. The area's ornithological importance has been recognised for a long time, and a permanent bird observatory was set up in 1946. Bird ringing has been carried out since the start and in a standardised way since 1972. Datasets from Ottenby have been used to assess long-term changes to migratory patterns, morphometrics and population trends for several species of birds, in particular waders.
