ANGLESEA ENVIRONMENT REPORT NOVEMBER 2008
peregrine falcons
In the last edition of the Environment Report, our
Peregrine Falcon chicks were downy white. But
they sure do grow up fast! With the webcam at
www.alcoa.com/falcons we have been able to
watch them gradually lose their down, get their
juvenile plumage, take their first flights and
eventually leave the nest. All in a month!
The chicks work up to the big ‘first flight’ with
hours of wing pumping at the edge of the nest and
venturing further out on the perch until they finally
take off. Stan was the first to take the plunge,
albeit a little prematurely. Concerned emails came
in from across the globe to ask where the little fella
had gone. Pt Henry security were even honoured
with a phone call from China asking of Stan’s
whereabouts. After several days had past with no
recent sighting, there were grave concern’s for
Stan’s welfare. But six days later and no worse for
wear, Stan was back in the nest box sharing his
story of adventure with his two big brothers.
As our fledglings have become more competent in
flight, they have moved away from the nest box to
learn how to hunt with their parents. Peregrine
chicks learn this in part through ‘playing’ - diving
and swooping each other in mid air. You may have
been lucky enough to see this activity around the
Power Station in the last two weeks. The parents
also capture prey for the fledglings to teach them
how to snatch it from them in mid air replicating
the hunting technique of the Peregrine.
This ‘playing’ can be deadly - able to reach speeds
of up to 380 km/h, the mix of high speed and
inexperience leads to high collision and mortality
rates in fledglings. Juvenile mortality is quite high in
Peregrine Falcons with 90% of Peregrines dying in
their first year. Here at Anglesea, Jet, Tess and
Dash were all lost within weeks of fledging from the
nest. Good news is, if they get through the first 12
months, they have a high rate of survival to
approximately 12 years of age.

OUR ENVIRONMENT AND OUR EMPLOYEE
Hi Lisa - so what are you doing here at Anglesea?
I am backfilling the Environmental Scientist’s role part-time.
Currently I am working on Anglesea’s EREP plan and a
Hydrogeological Assessment Gap Analysis
Where have you been working previously?
I have previously worked at Anglesea, Portland and Point Henry
as part of the Graduate Program. Most recently I have returned
from maternity leave.
Can you explain a little about EREP?
EREP is an Environment and Resource Efficiency Plan. Any
industry which exceeds thresholds of 120 ML water use or 100
TJ energy use per annum is required to report to EREP, which is
a department of the EPA. Alcoa Anglesea meets both of these
thresholds.
How is it important to what we do here?
EREP aims to encourage industry to minimise water and energy
use, as well as minimising waste production. It doesn’t change
what we do here at Anglesea very much, as we have already
done a lot of work in these areas. EREP will help us to maintain
the focus on minimising our resource use, particularly in to the
future when planning projects.
