Highly commended, mammals: Gelada after the storm – Marco Gaiotti (Italy). “Gelada baboons are the only monkey species in the world that feed on grasses. They are native to the tableland of Ethiopia. Every morning large family groups wander from their sleeping places in the steep rock face, up to 1,000 metres high, to the feeding grounds at the tablelands. This image clearly depicts their feeding strategy: they pull out bunches of grass, sort the stalks and then lift them to their mouth. This shot was taken towards the end of the rainy season after a heavy storm”. (Photo by Marco Gaiotti/2019 GDT European Wildlife Photographer of the Year)
