We are saying goodbye to many of our land
birds as they depart for warmer climes. But
sea birds continue to help provide nourishment for us and throughout the entire
world all seasons of the year. In the
1800s the world’s shipping lanes were very busy, but the huge oil tankers were
not among them. Nor did we have to cope
with oil soaked birds that may have landed in tailing ponds or on other beaches
and lakes.
Instead sea birds were providing our soils
with a valuable fertilizer called guano that is rich in nitrogen and phosphorus
and which now is largely replaced by commercial fertilizers. Sea birds such as pelicans, gannets, gulls,
petrels, penguins and cormorants are very busy checking out warm rest areas in
rainless coastal regions, or on islands where these birds gather together in
the Chincha Islands
off the coast of Peru . In the early 1800s the deposits on some of
these small islands were more than 100 feet deep. Many deposits are still found on South
Pacific islands. There are large
deposits of bat guano in caves in New Zealand . Farmers were able to raise organic foods for
over a century.
But other inland birds are active and
helpful as well and we have some inland forest species that are the size of
chickens, chiefly in Central and South America .
One wild turkey species called guans has
glossy back plumage and is usually dark green, crested in white, with a slate
blue throat. It survives chiefly on
insects and berries and ranges as far north as Texas .
Many of them roost in tall
trees and more kinds of geese, ducks and related varieties have been found in Canada as our
climate warms up.
One easily corrected problem with the vessels
that brought guano in the l800s was its potent fragrance. Too many harmful fumes emanated from the hold
below decks could cause breathing difficulties for the sailors. Large size print was inscribed on all sides
of the vessel. “SHIP HIGH IN TRANSIT,” as
the crew enlarged the size of the first letter in each word.
