Black noddy - The nests of these birds consist on a level platform, often created in the branches of trees by a series of dried leaves covered with bird droppings. One egg is laid each season, and nests are re-used in subsequent years.
Brown noddy - Etymology: Anous is Greek for "unmindful" , and stolidus means "impassive" in Latin . The birds are often unwary and find safety in enormous numbers. To sailors, they were well known for their apparent indifference to hunters or predators.
