There are only about 140 Guam kingfishers in the world and the species is extinct in the wild. At the Smithsonian Conservation Biology Institute we breed them to help create a healthy population in human care that could eventually be used to help release birds to the wild. #WeSaveSpecies #GuamKingfisher #Birds #Guam」7月3日 4時30分
