In this May 16, 2017 photo, an "Arara," or Macaw flies low over a ranch in Corumba, in the Pantanal wetlands of Mato Grosso do Sul state, Brazil. At different moments during a three-week pilgrimage in search of grass to graze for cattle, cowboys cross paths with macaws, deer and pit vipers, all seemingly unfazed by their presence.
