The African black oystercatcher is in danger of extinction, its
way of life increasingly threatened by man. It is the only oystercatcher
which breeds in Africa.
The oystercatcher is rarer than the Southern right whale and
there are no more than 5 000 birds in the world.
Just like Hartlaub's
Gull, despite its rarity in global terms, the oystercatcher is extremely
common in the immediate vicinity of the Beach House. One can see many in 1
day.

The oystercatcher has an all-black plumage
and a most striking orange-red eye ring and red iris and a long red
bill. It
has a haunting piping cry, often when flying, and may be seen in flocks as
a protection against predators out of breeding season. It has strong
shoulders and its blade-like bill can lever limpets off rocks in an manner
unmatched by any other bird.

her mouth. This one of a pair of oystercatchers that can often be seen feeding on
the tidal rocks opposite the
Beach
House. One can watch them from the
bedrooms!

The oystercatcher, which mate loyally for
life is vulnerable for a number of reasons: It’s nest is a scrape in the
dune. Two eggs are usually laid during summer at the height of the holiday seasons
in the Cape. The eggs and nest are not easily visible to the untrained
eye. Restricting pedestrian movement on their breeding ground, like the
dune in front of the Beach House, is highly favored because of this. The eggs
can easily be trampled on.
Although they may live for 35 years, the birds, which eat limpets and
mussels and not oysters, do not breed until they are three years old. The
birds can only feed at low tide and do so at day and night. Because of
their highly selective feeding area they are much more susceptible to
human activity than most shore birds. Disregarded or entangled fishing
line is lethal to oystercatchers as they become entangled in it.
