Moku Manu is also referred to as Bird Island because of its dense and most diverse seabird colonies. This islet is located off the Oahu coast and is a formation of debris slung from the Kailua Volcano. Similar to Manana, Moku Manu is also a state-protected seabird sanctuary. The island isn't a recommended location to land because of its unsafe beach and weather conditions. Its isolation makes it an excellent environment for nesting and rich marine life. Shorebirds like noddies, petrels, boobies, and several other migrating species are a part of the island's ecosystem.
