Population monitoring of the colony is conducted by David Hyrenbach, Professor of Oceanography, his students at Hawai‘i Pacific University, and Michelle Hester, Oikonos Ecosystem Knowledge. An annual colony count is completed during the peak incubation period (July 14) and once the chicks have hatched (September 14). In 2022, we documented 423 active nests. This is the highest count to date over the last 14 years.
