Europe’s last wild horses are driven into an arena to pick out young stallions in Duelmen, Germany. It is believed that this is the last herd of wild horses on the European continent in this 350 hectare reservation in western Germany, where more than 300 of the indigenous horses stay free and wild without any care under the protection of the Duke of Croy. Only once a year the new-born stallions are caught and sold, all mares stay with the herd and guarantee the survive of the endangered species

Birds nest in the branches of a tree at the protected natural area of La Barra in the city of Metapan. Dozens of birds have been found dead in the past few weeks in the government-protected area of La Barra, a nesting refuge for the white heron and other wild birds, according to members of the Salvadoran Association of Bird Rescue (ALAS). The members of the non-governmental organisation are researching if pesticide use in the cornfields located near the nature preserve is causing the unusually high mortality of herons and their chicks, and other birds in the area
