The White-flippered Penguin (Eudyptula
albosignata) is one of the world’s smallest penguin species.
1) How do they look
like? The White-flippered Penguin has an overall
blue-grey appearance, which is very similar to the Little Penguin
(Blue Penguin). They are distinguished with broad white
trailing and leading edges of the flipper. They typically grow
to 30 cm tall and weighing 1.5 kg.
2) How are they classified in penguin
families? The White-flippered Penguin was previously
classified as a subspecies of the Little Penguin(Blue Penguin), or
thought to be just a colour morph of the Little Penguin (Blue
Penguin). However, recent genetic analysis conducted by Dr
Baker in USA, looking at both nuclear and mitochondrial DNA, has
found the White-flippered Penguin distinct from the rest of the
Little Penguins (E. minor) and treated it as a full species.
Dr Baker stated in the petition prepared by the Center for
Biological Diversity for US Department of the Interior, Fish &
Wildlife Service that the two lineages diverged about 2.7 million
years ago.
3) Where on the earth do they
live? The White-flippered Penguin is endemic to
Canterbury, New Zealand. They breed only on Banks Peninsula
(2,200 pairs) and Motunau Island (1,800 pairs).
4) How and where do they make
nests? White-flippered Penguins lay their eggs in
a burrow lined with plant material, or in hollows under bushes or
rocks, in dunes, or on vegetated slopes of coasts and islands.
5) What do they eat? They feed on
small shoaling fish or squid, and less often on crustaceans.
6) How endangered are they? The
most recent estimate of the total population is only 4,000 pairs
(1,800 on Motunau Island and 2,200 on Banks Peninsula). They
are classified as “Endangered” by IUCN (The International Union for
the Conservation of Nature and Natural Resources) and Birdlife
International, and “Acutely-Threatened” by D.O.C. (Department of
Conservation, New Zealand). 7) What are their
threats? The key land-based threats continue to be
predation by introduced predators and habitat degradation by human
activities. At sea, White-flippered Penguins have been frequently
caught in near-shore set nets, especially around Motunau Island. A
large oil spill would be disastrous to this penguin, and the threat
is high because the birds nest in areas near shipping
lanes.
8) Have they been long
endangered? Before European settlement started around in
1850 to Banks Peninsula, there were tens of thousands of
White-flippered Penguins. They have disappeared from much of
their range since then, and are in much reduced numbers where they
have survived. Human settlement destroyed habitat outright and
predators have overrun many of the remaining colonies. In
recent study, the aggregate number of nests declined from 489 to 85
between 1981 and 2000: an overall loss of 83%. On Motunau Island
where no human lives without any predators, population has been
stable.
9) What are their
predators? Ferrets, Feral cats and Stoats are main
predators. Also, domestic dogs could be a major
threat.
10) What have been done to save
them? Some farmers on Banks Peninsula have been
privately taking actions to protect
White-flippered penguin. At Haris Bay next to Boulder Bay,
a colony has been re-established by Dr Chris Challies, using
"chick transfer" technique from Motunau Island. Around the
colony at Haris bay, predator fence has been set to protect the
area from the intrusion of predators.
11) Who are involved in their
conservations? Above mentioned conservation works have
been privately funded and privately initiated. Department of
Conservation has recognized necessity of more intense conservation
activities, however, due to limited resources, there is no
pro-active conservation actions have been taken by the
Department. The predator fence around Haris Bay has been
funded by Christchurch City Council, initiated by its co-operative
parking rangers, however, Christchurch City Council as a whole has
not been proactive to the conservations of White-flippered penguin,
even though they are the only endemic birds of its region.
There are some councillors who are supportive to the conservation
activities of White-flippered penguin, however, other
councillors have been showing no positive supports to the
conservation programs.
