This is a near-impossible question to answer since in most cases we don't know the exact moment a species goes extinct. Often there is a certain period of time without seeing the animal has passed before it is classified as extinct. According to BirdLife International, Hawaii's Po'ouli, a bird that has not been seen in the wild since 2004, went extinct since the last bird left in captivity died this year. There are many other wildlife that are now classified as extinct, but it is hard to specify the exact date as to when they became extinct. In March of 2018, the last known male northern white rhino died. There are two females still alive, so although they are not yet extinct, assuming there are no unknown northern white rhinos in existence, they will become extinct soon.
