Jerusalem Bird Observatory
The Jerusalem Bird Observatory is an urban bird observatory in Israel, sited on a 5000 m2 plot in central Jerusalem between the Knesset and the Supreme Court. It has a strategic location on the bird migration route between Africa and Eurasia along the Great Rift Valley. Every spring and fall more than 500 million birds migrate through Israel. Two-thirds of the species seen in Jerusalem are migratory.
Established in 1994 by the Society for the Protection of Nature in Israel, the observatory serves as the national bird banding center. It was founded, and is directed, by naturalist Amir Balaban and ornithologist Gidon Perleman. Two hundred birds are banded every day by trained volunteers during the spring and fall migrations.
