The manu-o-Kū, also known as the white tern or fairy tern, is a small, all-white bird with a short, forked tail, dark eyes, and a thick, pointed black bill with a blue base. Males and females are identical in appearance. Named the official bird of the City & County of Honolulu, the manu-o-Kū can often be seen close to human activity, frequently around Honolulu city parks.
