An Urban Colony
Bob Palfrey, a local mariner, reckons he started hearing penguins
in St Kilda harbour in 1956, not long after a breakwater was built
to provide shelter for yachts competing in the Melbourne Olympics.

St Kilda is just 5 kilometres due south of the Central Business
District of Victoria's capital - Melbourne. St Kilda is one of Victoria's
most densely populated suburbs and a busy tourist destination. Incredibly,
Little Penguins have made St Kilda harbour their home.
The Little Penguin (Eudyptula minor), also known as the
Fairy Penguin, is the smallest of the penguin family. It is an aquatic
animal, native to New Zealand and southern Australia, which only
comes ashore to breed and moult.

Important Note
Although these little penguins have chosen an urban "home",
they are still wild animals, dependent on their instincts to survive.
Too much interaction with humans may diminish a penguin's ability
to survive in the wild. For this reason, and the savage cuts inflicted
by a penguin's sharp beak, only people
with a permit to handle wildlife are permitted to handle them!

How Little Penguins Came to St Kilda
There are no documented records of breeding penguin colonies in
Port Phillip Bay prior to the St Kilda
colony. However, it is possible that small colonies may have
existed in relatively isolated places before human development and
introduced predators wiped them out.
The President of the Victorian Naturalists reported a penguin chasing
fish in the mouth of Kororoit Creek in 1911. Long-term residents
of Altona recall penguins coming in an out of burrows near the mouth
of the Laverton Creek.
A large colony of about 20,000 Little Penguins live in the sand
hills at Phillip Island. Every year half a million visitors watch
the famous "Penguin Parade" at dusk. Many birds in the
‘parade’ will be returning from Port Philip Bay.
In winter Phillip Island penguins travel the 120 kilometres to
Port Phillip Bay to feed. This is a round trip of 3 days.
The discovery at St Kilda of penguins that had been banded at Phillip
Island confirms that on at least a couple of occasions Phillip Island
penguins found the St Kilda breakwater
and took up residence.

In 1974 two nesting pairs of Little Penguins were recorded at St
Kilda. By 1986 a colony of about 100 birds had established itself
in the outer two thirds of the breakwater.
A conservative estimate for the year 2000 put the size of the colony
at more than 120 Little Penguins. Based on a formula developed by
Phillip Island Penguin Parade scientists the number of birds at
St Kilda now is about 540.
The rock structure of the breakwater makes the St Kilda penguins
relatively hard to catch or even see while they’re on land.
So estimating the size of the colony is a process of educated guesswork.
This is made all the more difficult by the fact that penguins don’t
necessarily return to land each day. They may spend weeks or even
months at sea.
