A great egret is seen at the Agamon Hula Ornithology and Nature Park in the heart of the Hula Valley, northern Israel, on Jan. 6, 2014. During every migration season (fall and spring), over 500 million birds from more than 400 species migrate in the sky above the Agamon Hula Ornithology and Nature Park. Thousands remain here during the winter, and others choose to nest here during the spring and summer.
