Some island in the world is
really awesome to see, just like remote offshore “Grassholm” which is a small
uninhabited island, nearly 200 meters across, located 13 kilometers off the
southwestern Pembrokeshire coast in Wales. This beautiful small island is home
to one of the largest colonies of gannets. Therefore; during the breeding
season starts from (April to September), approximately 39,000 pairs of birds,
nearly 10% of the world’s population, nest on the northern side of the island.
Therefore, this side of the island is well covered with a thick layer of bird
droppings, mainly famous as guano, giving the island its characteristic
off-white color.
From afar, the island looks
extremely beautiful when bun sitting on the ocean with icing sugar on top. So many visitors when approaches the island
by boat, the stench becomes overbearing. The lovely white patch on the island
that can be seen from above and off-shore, is neither snow nor limestone rock.
These’re birds themselves and their shit. The tiny island is made up of basalt,
an igneous rock of volcanic origin. It is well believed by researchers that the
island was once a part of Skomer Island before it got loose during the last Ice
Age. If you see the history you’ll came to know that during the late 16th
century thousands of Puffins inhabited the island but now there are none.
Because the existing soil
condition aren’t supported burrows that these birds normally make which is
maybe why they’ve moved to the neighboring Skomer and Skokholm Islands.
However; Gannets have increased their colonized in the island in massive
numbers, perhaps arriving from Lundy Island where they were disturbed. Although
Grassholm island covers only 22 acres and there’re more than 80,000 Gannets
plus their chicks, colonies of Guillemots, Razorbills, Kittiwakes and Shags.
The gannets were first observed
on the island in the mid of 18th of century roughly in between 1860 and in
1872, at that time only 12 pairs recorded as breeding there. But at the late 18th century somewhere 1890's
there were 200 or more birds breed. Therefore; in 1905 Cardiff Naturalists
Society recorded 300 more breeding pairs. So Gannet population has been
steadily increasing since then and now they’re in countless numbers. The birds
live in very near proximity to each other and have evolved a series of vocal
and postural messages. They’re always thousands of numbers in the air above the
island, and would like to dive fishing from all angles at great heights.
The cacophony of sounds they make
is deafening. Moreover; the guano had killed the dense mattress of grass in
this island exposing archaeological remains of settlements from the Iron Age
and early Medieval periods. So as you approach the island you’ll understand why
it is white? And the noise and the smell of Grassholm is really a lifetime
experience. The Gannets usually stay on Grassholm from February to October, and
after that they’d like to travel as far south as Africa in the winter. The
older birds will stay in European waters. Make sure there is no landing on the
island but boat trips are run daily, subject to weather conditions.
