An article in Nature [0] has a few more details, including the fact that problems with the drones meant that only half of one island was baited by drone, and the rest of the island had to be done by hand. Looking on the bright side, Island Conservation, the Californian group that is conducting the operation, see this as having set up a controlled experiment (i.e. drone delivered baiting vs. hand delivered). Only one of the smaller islands was involved, not the whole group. [0] https://www.nature.com/articles/d41586-019-00176-z https://www.nature.com/articles/d41586-019-00176-z
