peregrine falcons
Spring is here and the neighbourhood won’t be the
same.....the Peregrine Falcons are back in town once
again returning to their purpose-built nest box on
the water tower at Alcoa Anglesea. And this year
we get a birds eye view of all the action with the
webcam live and online.
With the arrival of the fourth egg the incubation
period begins. A familiar sight for the next 33-35
days will be Sheila, the female adult, in the next box
with her four eggs tucked neatly underneath as the
eggs are rarely left uncovered during this time.
Last year in a Victorian first, Alcoa Anglesea
installed a webcam on the nestbox, broadcasting
the images of the Peregrine Falcon pair at
Anglesea over the internet. After the fledgling Uno
departed in December last year, the camera was
switched off as the falcons dispersed to their nonbreeding territories. The webcam at
www.alcoa.com/falcons is now back online for
another season providing us images of day-to-day
life in the Peregrine Falcon nest from the arrival of
the first egg until the last fledgling departs.
A quick calendar check and it looks like an
expected hatching date between the 29th of
September and the 1st of October. However
we’re not ones to count our eggs before they
hatch. Despite laying four eggs last year, only one
egg successfully hatched. Whilst there is no
explanation for why this happened, the presence of
unhatched eggs at other nests across the state
suggested the cause was wider spread and may
be the consequence of drought conditions. Only
time will tell whether this year proves more
sucessful.
There’s been plenty of action so far with almost daily
updates placed on the website capturing the arrival
of the pair’s four eggs.
In the meantime, stay tuned to the website for further
exciting developments and observe the goings on
from the safety of your office computer.

OUR ENVIRONMENT AND OUR EMPLOYEES..
Lee, your job seems to take you up onto the floors of
the Power Station a bit, what are you doing up there?
The electrical group has equipment to service and maintain on all
floors of the power station. Air blowers, oil burners, lighting, water
cannons, thermocouples & critical valve controls, to name a few.
We hear you have had some interesting encounters
with the site’
s Per
egrine Falcons in the few years.
site’s
Peregrine
What’
s gone on? Recently after responding to a breakdown
What’s
on the 7th floor hoist I decided to use the stairs instead of the
elevator (for personal fitness reasons). As I was accessing the
first step my feathered friend decided on a very swift territorial
swoop, this took me by surprise. Similar happened last season
whist repairing lights on the 5th floor.
Do you have any advice for others? These birds move at
very high speeds and because of plant background noise,
hearing protection PPE and plant structure they can easily
surprise. If your work takes you to the upper levels of the boiler
keep a keen eye out for the the falcons as I’m sure that they
keep a close check on us. Three point contact whilst accessing
stairs is very important. Keep tools and materials in a managed
fashion that reduces any risk of them falling down the structure.
