SCPtember 2-- SCP-1505

Talk about birds of a feather flocking together! SCP-1505 is a raven that duplicates itself every ten hours, causing its numbers to increase exponentially and increasing to potentially world-threatening levels. The duplicates disappear if the individual they duplicated from is killed, and in theory SCP-1505 can be destroyed if the original specimen can be located and killed. Unfortunately, no one has managed to do that yet.
