A Small but Mighty Treasure
Western Snowy Plover
(Charadrius alexandrius nivosus)

The Western Snowy Plover is a small
bird found along the western coast of North America. It is most commonly
spotted along the coasts of California, Oregon, Washington, and even down into
Baja Mexico. It is generally about 5.9 to 6.6 inches long and weighs between
1.2 to 2 ounces. It receives its name of “Snowy Plover” because of its large
white puffy belly. The Snowy plover’s back and wings are grey and it has
several dark patches on its neck and shoulders. It has a thin dark bill and its
particularly characteristic dark grey or blackish legs. They are usually found
on the beaches where they forage for small invertebrates in the sand. They also
nest and lay their eggs on the shore. If you have walked on the west coast beaches you have likely seen these little guys running around. The male plover assumes most of the
duties of raising the chick but instead of feeding it, he leads it to suitable
feeding areas.

A Threatened Species
The
Western Snowy Plover was listed as "Threatened" on the Endangered Species Act in
1993. If nothing is done to protect this species soon they are likely to become
endangered. These shorebirds were once widely found along the Pacific coast but
their number of breeding grounds has been declining. In Washington, the Snowy
Plovers used to nest at five locations along the coast which has now decreased
to three only five years later. In Oregon they were found nesting at over 29
locations which has now dwindled down to a mere ten breeding locations. A
similar pattern has been found along the coast of California.

Causes for Population Decrease
The populations of snowy Plovers
along the coast have been steadily declining. The primary threat of the Snowy
Plovers is habitat destruction and degradation. Human disturbance plays a large
role in the declining populations. The breeding season for Western Snowy
Plovers is during the summer season which is when most people actually spend time
on the beach. Many human activities including running, horseback riding, dune
riding, and campfires are all factors that are destroying the habitat that they
breed, feed, and survive in. Urban development is also laying waste and taking
over many of the beaches in which these snowy plovers live. Many condos,
houses, and hotels are being built along the coast as well as piers and
marinas. These not only remove some of the habitat that Western Snowy Plovers
require for survival but it is also making the other areas in which they
currently use for survival more unstable and susceptible to the natural forces
of the Earth. European beach grass
(Ammophila arenaria) has also taken over much of the habitat that these
shorebirds survive in.

Recovery Plan
The recovery plan for the Western
Snowy Plover primarily focuses on increasing their population and protecting
and monitoring their environment. The main goal to remove the Snowy Plover off
of the Threatened list is to increase their population to at least 3,000
breeding adults and to maintain that standard for ten years in three recovery
units along the Pacific Coast. During the last five years of recovery there
must be a productivity of at least one chick per male. In order to protect
their breeding habitats nests and enclosures are set up along beaches in order
to protect them from predators. Restrictions on vehicles, dogs, and other beach
activities are being enforced near their breeding sites.
