FLORA
Blanket peat covers much of
the island, providing a globally rare but important wildlife habitat.
This peat
is formed from the compression of dead (but not decomposed) plant remains
and forms at the rate of about 1 mm a year. In places this peat is over 3
metres in depth (3,000 years). Look carefully for 2 special plants,
butterwort and sundew which can be found on the moorland. Both these
plants supplement their diet with insects, by trapping them on their
leaves.
BIRDS
In
summer, Yell's moorlands are alive with breeding birds Whimbrel, redthroated
divers, dunlin and golden plover can all be seen from the roadside. The
sharp eyed observer may catch a glimpse of Britain's smallest bird of prey
the merlin, as it dashes after small birds. Great skuas or bonxies as they
are locally known, Arctic skuas, and eider duck, also nest on the moorland.
Arctic terns (tirricks) the
harbinger of summer, can also be seen but please try to avoid walking near
their breeding colonies as they will defend new eggs and young most
vigorously. Remember these Arctic terns fly from the Antarctic to spend
their summers in Yell with you!
Six species of gull nest on the island, the commonest being the herring
gull. Along the coast, fulmars and black guillemots are common with
puffins, shags, guillemots and kittiwakes nesting on the sea cliffs.
