Birds can help the Middle East nest : Israel is the central bus station for bird migration. Incredibly, 500 million birds pass through or over this narrow country - storks and eagles and pelicans shuttling twice a year between Europe and Asia or Africa; songbirds wintering in the milder climate here or move farther south. Mr Leshem, an ornithologist, hopes to use the pivotal location of Latrun in Israel to learn more about the 530 species of birds known to pass through here. He is setting up a program that will link Israeli, Palestinian and Jordanian students through the Internet in an effort to track and observe the migrating birds.
