Johnston Atoll National Wildlife Refuge

small state map showing location

Johnston Island, Pacific Islands


NOTE: Parts of or all of Johnston and surrounding islands may be inaccessible to birders because of military operations.

Of all the wildlife at Johnston, the birds are the most conspicuous, if only because humans spend most of their time out of the water. Most of the birds that occur at Johnston are seabirds. Seabirds obtain their food from the sea and generally possess webbed feet and beaks adapted for feeding on fish and squid. They also have characteristic internal salt glands that make it possible for them to drink sea water. Long narrow wings efficient for soaring are found in many species.

Seabirds are among the longest lived birds in the world, and life spans in excess of 30 years are not uncommon for some species. Compared to other, they produce fewer young over their lifetime, and the young take longer to mature--up to 7 years for some species. Many seabirds mate for life, and both males and females incubate, brood, and feed their young.

Seabirds evolved on islands where natural predators were absent, therefore, they lack a well developed fear of people or predators. Their long lives and the ease with which the chicks and adults can be captured for banding and marking make them ideal subjects for long term studies. Seabird population numbers and movements can quickly reflect changes in the ocean environment.

Other migratory birds occurring at Johnston Atoll include species that breed in Alaska, Canada, the mainland United States, and Asia, and migrate to the South and Central Pacific for the winter. These include many shorebirds and occasional waterfowl, hawks. owls, and egrets. Some species like the bristle-thighed curlews and Pacific golden plovers may make a 6,000 mile round trip voyage between their South Pacific wintering areas and arctic breeding areas.


Relative abundance is coded as follows:

a - Abundant (numerous common species)
c - Common (certain to be seen in suitable habitat)
u - Uncommon (present, but not certain to be seen)
r - Rare (seen only a few times a year or not at all)
x - Accidental (not normally expected)

Nesting Habitat:

1 - Burrow
2 - Rock crevice
3 - Ground
4 - Shrub or tree
5 - Branch or ledge
6 - Under vegetation
