Israel, located at the junction of three continents, is crossed by migrating birds on a scale unparalleled anywhere.
Studies show that about 500 million birds cross Israel’s narrow airspace twice every year in the course of their migrations.
Consequently, Israel has become an attraction for bird enthusiasts worldwide.
Research on migrating birds in Israel, based on satellite and radar monitoring, makes it possible today to track the birds from Israel to their winter nesting grounds in Africa, and back northward, via Israel, to their summer nesting grounds in Europe.
