A gray four-eyed opossum (Philander possum) with its young is released into its natural habitat along with other species in Chinandega, Nicaragua, 28 February 2021. All these animals, mostly rescued from abuse and trade, were returned to the wild, previously trained to survive, although some, such as opossums and foxes, were fearful when leaving and stayed quite close to their rescuers.
