African Penguin
Ambassadors in Zoos and Aquaria
The 25th Annual
Conference of the European Association of Zoos and Aquaria was
hosted by Antwerp Zoo in Belgium from the 16 to 20 September 2008.
The Dyer Island Conservation Trust was invited to address the
Penguin group on the wild African Penguins. Wilfred Chivell and
Lauren Waller attended the meeting on behalf of the trust and gave a
presentation on the status of African Penguins in the wild and the current threats they face, as well as latest African Penguin research and conservation projects. The talk also highlighted the role that the Dyer Island Conservation Trust is playing in these projects, and discussed the building of partnerships with European zoos and aquaria where their African penguins can act as ambassadors for their wild counterparts. The talk was very well received with the members showing keen interest (and dismay) at the declining African Penguin numbers and a willingness to support conservation and research where they could.
The trip also provided Lauren and Wilfred to meet up with the
Head of Research and Curator of Birds from Bristol University who
are long time supporters of African Penguin research and
conservation and who will be working more closely with the DICT in
future with African Penguins.

Film crews
visit Dyer Island & rescue of orphaned African Penguin
chicks
Two local film crews visited Dyer Island recently, the In
Sync crew (August 2008) and Wild Ltd crew (November 2008), both
filmed documentaries to raise awareness of the plight of the
vulnerable African Penguin and the success of the artificial nesting
project.
On Dyer Island, chicks that hatch late in the season
(September onwards) are sometimes abandoned by their parents who
need to prepare for their annual moult. Every penguin needs to
replace their old/worn feathers each year in order that they are in
top condition for the next breeding season. Their feathers need to
be completely waterproof enabling them to survive the cold Atlantic
waters and stay at sea long enough that they can catch enough fish
for themselves and their chicks. During the moult period, adults are
unable to feed their chicks and if not removed from the island,
these chicks will die through a lack of food. Due to the massive
decline in penguin numbers, Dyer Island Conservation Trust and
CapeNature remove these chicks to bolster the wild colonies. This
year, 40 orphan chicks were removed from Dyer Island and transported
to the South African Foundation for the Conservation of Coastal
Birds (SANCCOB) for hand-rearing. The fledglings will then be
re-introduced to the wild around mid December to January. In 2006,
SANCCOB reared 841 orphaned chicks and another 481 in 2007. Research
has shown that these hand-reared and released chicks show higher
survivorship than their wild counterparts, making each individual
chick extremely valuable in conservation efforts of this vulnerable
species.
Collection of
Seal Scat on Geyser Rock
On the 31st October 2008, Steve Kirkman (PhD student
researching the ecology of the Cape fur seal in southern Africa), of
the University of Cape Town, and Wilfred Chivell went out to Geyser
Rock to collect seal scat samples for dietary analysis, so as to
ascertain the prey composition of the Cape Fur Seals in the Dyer
Island area. This is the least intrusive way of determining a seal's
dietary habits, and involves examining samples for fish otoliths,
squid beaks, feathers, and so on. One can then ascertain which
species and sizes of prey the seals are consuming, where after
appropriate management and conservation options can be
addressed.
Whale Stranding
on Pearly Beach
On 23rd October 2008, a Southern Right Whale calf, estimated
to be at least four months old, was found stranded on Pearly Beach,
with no apparent injuries. The Dyer Island Conservation Trust (DICT)
assists Dr Peter Best, Meredith Thornton and colleagues, of the
Mammal Research Institute (University of Pretoria), housed at the
South African Museum in Cape Town, with data collection when such
events occur locally. With no reason for death evident, Wilfred
Chivell, founder of DICT, collected skin samples from the whale, as
well as numerous amphipods from the skin surface. The skin is used
for a study on the fungi that grow on whale skin, which is a
co-operative project with the Mammal Research Institute and
Stellenbosch University. The eyes were also collected for a
comparative study with Bowhead Whales. This project aims to use the
lens of the eye to determine the age of the animal. At the Museum,
research is undertaken on the ecology, population dynamics and
behaviour of cetaceans in the waters of southern Africa, with the
principal objective of providing information that will promote their
conservation. They also train students, do environmental education
and are engaging with the fishing industry in order to reduce whale
entanglement. Apart from fieldwork on live animals they also collect
stranded specimens to add to the Museum's marine mammal collection,
including both skeletal and histological specimens.
Faces of Need
Update
2 898 nests have been sold to date.
July was the peak breeding season for the African penguins on
the island, and many of the penguin houses were found with chicks
and/or eggs. A maximum count of 1 600 breeding pairs of African
Penguins was counted in July on Dyer island. A rather depressing
figure when you consider that in 1979, this figure was over 22 000
breeding pairs.
The penguins are currently moulting on Dyer Island. African
Penguins moult once a year and this period is crucial for the next
breeding season. During this period, the penguins replace all their
feathers. By doing so, they keep their feathers in tip top
condition, providing them an insulative and waterproof layer that
protects the penguin while swimming in the cold Atlantic waters. The
penguins are then able to spend many hours at sea finding fish for
themselves and their hungry chicks.
Good news for our penguins is that half the South African
coastline will enjoy extra legal protection from oil pollution from
August when a new "special area" is declared by the United Nations.
This internationally protected area stretches from Lamberts Bay on
the Cape West Coast to East London. As from August 1, it will become
an offence for any oil tankers and other large ships to clean out
their cargo or "slops" tanks, or to dump oily wastes in this special
area.
There are still many homeless penguins on the island. You can
purchase a nest online via via our secure website.
Faces of Need
Sharks
The Faces of Need sharks project is a five year monitoring
program aimed at estimating and establishing reliable population
studies on the above key shark species. Through research, education
and out reach programs the Dyer Island Conservation Trust and the
South African shark Conservancy (SASC) are teaming up to start the
project as soon as possible. Eventually the aim is to implement
sustainable catch quotas for the locally exploited species and
compensate local fisherman's livelihood. To read more on this
exciting project... click here.
Supporters
Welcome to
Multi Spectrum Property Group (MSP Group). MSP Group has pledged,
after delivery of the initial 20 homes, to deliver a penguin home
for every home we deliver to our clients. The MSP Group anticipates
to deliver 1000 residences in 2008 translating to 1000 penguin
breeding pairs which will receive safe homes in which to raise their
chicks. As a group they are dedicated to the conservation and
protection of our natural environment.
Thank you MSP and we look forward to being able to house many
more penguins through your support.
