Kelsey, E.C., Adams, J., Felis, J.J., Stenske, J.G., and Horton, C.A., 2022, Digital imagery used for aerial counts for surface-nesting seabirds at Lehua Island and Moku Manu Islet and Ulupa'u Crater, O'ahu in 2019: U.S. Geological Survey data release,


We have incorporated the Hawaiian language spellings of place names however, software limitations for metadata files did not allow for inclusion of the appropriate diacritical markings. Among important seabird breeding sites in the main Hawaiian Islands (MHI), Lehua Island off Niʻihau, and Moku Manu Islets off O'ahu support diverse and abundant seabird breeding populations. Both offshore islands provide excellent nesting habitat for surface nesting boobies (Sula spp.) and Moku Manu also supports nesting habitat for relatively large breeding populations of Sooty Tern (Onychoprion fuscatus) and Brown Noddy (Anous stolidus). Additionally, Ulupa'u Crater, near Moku Manu on O'ahu, is one of only a few main island sites and the only site [...]

This data release provides supporting data used to count or estimate population sizes of six surface-nesting seabird species: Brown Booby (Sula leucogaster), Red-footed Booby (S. sula), Masked Booby (S. dactylatra), Great Frigatebird (Fregata minor), Sooty Tern (Onychoprion fuscatus) and Brown Noddy (Anous stolidus) present at one or more of three nesting sites in the Main Hawaiian Islands (Lehua Island, Moku Manu Islet, and Ulupa'u Crater) during the 2019 breeding season.
