I've often joked that there's a Heron that watches over me. In LA, Spain, Vanuatu, The Dominican, and here in Toronto. I'd swear it's the same bird.
And then there's Yaren, a Stork that lives half the year in Africa and half the year in this livestreamed nest in Turkey.
Yaren not only returns to Turkey every March, she returns to the same friend, a Turkish fisherman named Adem Yılmaz. They've spent each Spring and Summer together since 2010.
