Spring has hardly begun when high up in the spire a piercing cry is heard. You must raise your head to admire two large birds flying together, alternating acrobatics and motionlessness in the sky, like two silver kites playing with the wind. Their light-coloured, squat silhouette and their darker head help to identify the short-toed snake eagle. They mainly feed on reptiles (lizards and snakes), which they capture by the head and regurgitate to feed their chicks.
