KIM LANDERS: Against expectations a determined colony of little penguins
in South Australia is fighting back after years of population decline.
Mystery
still surrounds why there was a dramatic drop in birds on Granite
Island. Numbers fell from more than 1500 to between 20 and 30.
While researchers say the population is stabilising, locals could now be putting the birds at risk by
using torches and bringing dogs onto the island.
Our reporter Natalie Whiting visited Granite Island and filed this report.
STEVE HEDGES (excerpt from penguin tour): Stephen is my name and I am looking forward to tonight's tour...
NATALIE
WHITING: It's dusk on Granite Island, just off the coast of Victor
Harbour, and local Steve Hedges is leading a penguin tour.
STEVE
HEDGES (excerpt from penguin tour): We're going to start our tour here.
This is probably one of their favourite landing spots just in here
where...
NATALIE WHITING: It's harder to spot a penguin here than it once was.
STEVE HEDGES (excerpt from penguin tour): All right, looks like no-one's in tonight.
NATALIE WHITING: March is also a notoriously hard time to find penguins because they aren't breeding.
(Sounds of people walking)
NATALIE WHITING: A small group of tourists follows as he searches burrows.
So it took a little over an hour, but we did end up finding one. What can you tell us about this penguin in front of us?
STEVE HEDGES: Well, it appears to be a male because we are getting a little bit of a growl coming back.
But
it's been fascinating that this one has been coming in and staying in
for nearly a week now, which is a surprise because normally I would be
thinking it would be getting hungry and heading off.
NATALIE
WHITING: In 2012 there were 1500 penguins on the island. That's slowly
declined until 2012 when just 28 penguins were counted.
The figures from last year's census have just been released. Twenty-two birds were recorded.
Dr
Diane Colombelli-Negrel is a penguin ecologist at Flinders University
and has been studying the fall in penguin numbers for three years.
A number of factors are thought to have contributed to the decline.
DIANE
COLOMBELLI-NEGREL: Well at the moment, the big emphasis is on parasites
because we know that on small population that can have a drastic
impact.
NATALIE WHITING: Now that the colony has stabilised, Dr
Colombelli-Negrel says the population needs ongoing protection to
rebuild.
DIANE COLOMBELLI-NEGREL: This is very important with a
small number to be careful about how people behave with those penguins
and to be aware that they're there.
NATALIE WHITING: Unfortunately the big drop has convinced many people that the penguins are gone.
DIANE
COLOMBELLI-NEGREL: Every single day that we're out there working on the
penguins, we have comments from people saying, "there's no penguin life
on the island".
We are trying to run some workshops, some
public talks, but we are not getting a lot of interest because I think a
lot of people think there's no penguins anymore.
NATALIE
WHITING: There's concern about people making a lot of noise or using
torches at night. The white light can blind the penguins for hours.
But Steve Hedges believes word is spreading in the community about the remaining penguins.
There's also a dedicated group of locals helping the birds.
STEVE HEDGES: We are monitoring every night on Granite Island. There's a lot of people interested, lots of people keen.
NATALIE
WHITING: There is some rejuvenation work happening, some burrows been
built and plants that the penguins will appreciate.
How important is that sort of work in hoping to attract and keep the colony?
STEVE
HEDGES: I think it's crucial because if all the factors that are
putting them under pressure maybe out at sea, it could be their health,
it could be food, it could be climate factors, if their home, where
their burrows are, if we can do the best we can with that part of their
lives, if we can make that part of it successful, then we're doing all,
hopefully all we can.
