Drone footage of Israel's delayed crane migration

Thousands of cranes made a pit stop in Israel

They migrate from Russia, Finland and Estonia

to Ethiopia's Lake Tana each year

Location: Hula Lake Park

(SOUNDBITE) (English) YARON CHARKA, CHIEF ORNITHOLOGIST FOR THE JEWISH NATIONAL FUND, SAYING: "Migration is like the big clock of mother earth, of nature. And you see this clock ticking every year and ticks very similar every year, seasons are coming, birds are coming on their right time and you also see differences between years."
