| |  Imagine a bird the size of a
robin
surviving on the open seas. A bird like a Fork-tailed Storm-petrel, which weighs less than a stick
of butter
and is covered with seemingly fragile feathers, can weather winter storms, drink saltwater for
refreshment and
sleep comfortably on the rollicking waves. Pelagic (ocean-living) birds live dramatic lives and
seem to get
along quite well in harsh aquatic environments. They would shun land completely except for one
critical
period of their lives - breeding. Marine birds must return to the land in order to lay their eggs
and during
this time, they crowd onto the most remote, severe pieces of real estate they can find - the
offshore islands
and sea stacks. Some, like Rhinoceros Auklets, Cassin's Auklets and Storm-petrels burrow into any
available
soil and deposit an egg deep underground. Others, like Common Murres and the cormorants, choose
exposed cliff
sites to either build a nest, or merely lay and egg on the rock and sit on it. But as soon as the
young are
developed enough to leave, all return to the relative safety and bounty of the open sea.
The Olympic Coast
Sanctuary
is used by nearly 100 different species of marine birds and shorebirds. Many of the birds that are
here in
significant numbers in the summer time are actually not local breeders. Sooty Shearwaters, one of
the most
abundant birds found during the summer, have colonies off South America and Australia/New Zealand
but many
spend their "winter" in the Eastern North Pacific. Black-footed Albatross, our most common
albatross, nest in
the central and West Pacific (Hawaii and Japan) but many juveniles spend their formative years
cruising
relatively near our offshore waters. Northern Fulmars breed much further north in places like the
Pribiloff
Islands and the Alaskan Peninsula yet are a common sight in the Sanctuary once you get off
shore.
Tufted Puffins,
Common
Murres and Rhinoceros Auklets are all in the family Alcidae and so, with other species, are
referred to
collectively as "alcids" and several species of alcids breed in the sanctuary. Each alcid species
has a
distinctive bill shape or color uniquely designed for fancy food hunting (usually fish, although
some species
eat only plankton) and for mate recognition. All seabird species, whether they nest in our region
or only
migrate or winter here tell us something about the health of our marine ecosystem. They breed more
successfully when food is abundant, they are sensitive to water contamination such as oil, they
respond to
human disturbance and sometimes suffer from intruders to their nest sites. By admiring, studying
and
observing marine birds we can learn much about the ocean as a whole.
Not all coastal
birds are
truly pelagic. Waves of thousand upon thousand of migrating shorebirds use the the coastline like
a road map.
Their stop-off sites are few and far between yet critical to the success of their migration.
Shorebirds and
other migrating birds like waterfowl need to congregate in sheltered areas with abundant food to
fuel their
journeys. Loons, grebes and ducks abandon their freshwater breeding grounds in the late summer and
often
spend their winters in the nearshore ocean environment. Bald Eagle, Osprey and Peregrine Falcon
nests dot the
coastline, taking full advantage of the fish and bird abundance to feed their young. These birds,
though not
truly pelagic, are inextricably woven into the fabric of the ocean tapestry.
