In December 2010 Hiroshi Hasegawa of the Biology Department, Toho University counted 481 breeding pairs, up by 35 from the previous season's count of 446.
Of this total, 79 pairs were counted breeding at the less exposed site on the island where models have been used to attract birds. The previous season there were 57 breeding pairs at this locality. The main colony is on a steep slope made of volcanic sand at risk to landslides and erosion.
