Description
& Characteristics:
The seclusive
Snares Island penguin inhabits and breeds along the sheltered,
forested beaches of the Snares Islands, off the southern coast
of New Zealand. Members of the crested penguin group (Genus
Eudyptes), which also includes: Rockhopper
penguins, Fjordland
Penguins, Macaroni
Penguins,
Erect-crested Penguins, and Royal
penguins, Snares Island penguins are considered a very
vulnerable species. The low numbers and limited breeding areas
of this non-migratory species make them susceptible to a variety
of natural and human disturbances. The New Zealand government
has undertaken significant efforts to protect and preserve
both Snares Island habitats and marine feeding grounds.
Also called
the Snares-crested penguins, Snares Island penguins have a
broad crest extending from the beak to the back of the head.
They have a thicker, heavier bill which is underlined with
white skin. They have broad crests growing from the beak around
to the back of the head. It can be somewhat difficult to distinguish
the Snares Island penguins from some of the other crested
penguins, especially while they are at sea. Snares Island
penguins do not have the white cheek feathers found on the
Fjordland crested penguins. Also, their crests are not as
erect as those of the Erect-crested penguins and less elaborate
than those of the Rockhopper penguins. Male and female 'Snares'
are monomorphic and it can be difficult to differentiate the
sexes without behavioral clues.
These
Penguins eat a variety fish, squid and krill which populate
the warm waters of Southern New Zealand. As most penguin species
do, they feed by shallow pursuit diving, using their webbed
feet and strong flippers to propel them through the water
at speeds up to 15 miles per hour.
Breeding
season for Snares Island penguins begins in early summer and
there is often much fighting and jockeying for territory and
resources within the colonies. Preferring forest or shaded
vegetation, mated pairs scrape out shallow holes in the ground
which they line with grasses, leaves, twigs, and branches.
Once the nest is prepared, the female Snares will proceed
to lay two eggs; however, the first egg often fails to hatch.
The remaining egg is then incubated for one to two months
with each parent taking several long shifts. Once the egg
hatches the male broods and cares for the chick for three
weeks at which time he will join the female on foraging trips.
For protection, the young chicks will join with other chicks
to form a 'crèche' or nursery group while they wait
for their parents to return with food. Both parents feed the
chick daily until has molted (usually in about 75 days) and
is able to provide for itself.
