Storks lay bound on the floor before they are set free on the great Hungarian plains in Hortobagy, about 180 km (112 miles) from Budapest, April 6, 2011. Every year, employees of Budapest Zoo capture storks that are too young to make the journey south to Africa before the onset of winter in order to help them survive the cold months before setting them free in warmer weather.
