opens out in to a 30M diameter pool at the
end with gullies leading off this.

The Duvillaun Islands are also of
ornithological interest for their colonies
of breeding seabirds and wintering geese.
They hold the second largest colony of
Great Black-backed Gull in Ireland (217
pairs during 1985-87). Other nationally
important colonies include Cormorant (185
pairs), Shag (30-50 pairs), Fulmar (500
pairs), Common Gull (20-50 pairs) and
Black Guillemot (80 individuals). Large
numbers of Herring Gull are also found
(300-400 pairs) (all figures are from
1981). Storm Petrel occur on Duvillaun
More (14 colonies in 1966, total numbers
are unknown, but probably at least 100
pairs).
The islands are also used as a wintering
ground for internationally important
numbers of Barnacle Geese (420-450
individuals in 1988), which interchange
with the largest Irish population on the
nearby Inishkea Islands.
The island was abandoned after
the turn of the century. In the 1821 census
there were 19 living on the island, and a
community existed here up to at least 1917.
The ecclesiastical remains are of a small
anchorite settlement being an eremitic
establishment of the 6th to 10th centuries.
The square ruin is a killeen, with childrens' graveyard. A carved flat stone
depicts a Greek crucifixion. Well worth the
visit.
The Duvillaun Islands comprise a group of
marine islands, rocks and reefs 3 km off the
southern tip of the Mullet Peninsula, Co.
Mayo. The main islands included are
Duvillaun More, Duvillaun Beg, Turduvillaun,
Gaghta Island, Keely Island and Leamareha
Island.
The Duvillauns form part of a larger group
of islands, together with the Inishkeas,
Inishkeeragh and Inishglora, which hold an
important breeding population of Grey Seal,
an animal listed on Annex II of the EU
Habitats Directive. Estimates in 1995 for
the total minimum population of this
assemblage put the number of animals in the
range 539-693, about a third of the known
breeding population in Ireland.
Approximately two-thirds of Duvillaun More
is covered by grass, and the island is
grazed by sheep and rabbits. The other
islands support little or no vegetation. The
main threat to the Grey Seal population at
this site is from illegal culling; nesting
birds would be vulnerable to disturbance
during breeding.
Belmullet has
lots of Island to dive and explore
