Kāohikaipu (also called Black Rock) is a tiny island, known as an islet, located in Honolulu County, Hawaii. It's a small piece of land, only about 11 acres in size. Kāohikaipu sits just 0.6 miles away from another nearby island called Mānana Island, which people sometimes call Rabbit Island. Both Kāohikaipu and Mānana Island are found northeast of Makapuʻu Point in Hawaii.

How Kāohikaipu Was Formed
Kāohikaipu was created by ancient volcanoes. It's part of something called the Honolulu Volcanics. This was a series of volcanic eruptions that happened a very long time ago. These eruptions came from the Koʻolau Range, which is a mountain range on the island of Oahu.
Volcanic Eruptions and Landforms
The Honolulu Volcanics created many interesting landforms around Honolulu. For example, famous spots like Diamond Head were also formed during these eruptions. Kāohikaipu itself is a special type of volcano called a Tuff cone. A tuff cone forms when hot magma mixes with water, causing explosive eruptions that build up layers of ash and rock.
A Home for Wildlife
Kāohikaipu is a very important place for animals. It is a wildlife sanctuary, especially for birds. This means it's a protected area where birds can live safely without being disturbed.
Protecting the Island's Birds
Because Kāohikaipu is a sanctuary, people need special permission to visit it. This rule helps to protect the birds and their homes on the island. It ensures that the natural environment remains safe for all the wildlife that lives there.
