peregrine falcons are back!
Our Peregrine Falcon pair is back for 2009! Havoc
and Sheila returned to Alcoa Anglesea in June,
which was much earlier than last year. As usual,
we will have a bird’s eye view of all the action with
the webcam live and online.
Sheila laid her first egg on August 28 and another
two on August 31. However, due to the large
amount of time Sheila is spending in the nest box,
it wasn’t until Sept 7 that we discovered she has
actually laid four eggs this year!
As you may notice from the photo, the falcons are
no longer in the pink nest box. Last year Sheila
increased the ferocity in which she defended her
territory, including a number of strikes to our
employees. One possible contributor to Sheila’s
bad mood was that the nest box faced directly
toward the power station (north west). This may
have been a source of aggravation for Sheila as
she could see the people moving back and forth
and felt her nest was threatened. So a new nest
box has been installed on the north east side of the
water tower facing away from the power station.
The incubation period will now begin, and Sheila
will sit on her eggs for the next 33-35 days, rarely
leaving them uncovered during this time. The
hatching date is expected to be around the 30th
September.
As yet, we have not had any reported swoopings.
However, the greatest amount of swooping
activity occurs from late Sept to early Dec when
the chicks have hatched and the female is no
longer tied to the nest. Stay tuned to see if our
nest box relocation is a success!
Last year Sheila laid four eggs, of which three
hatched, giving us three males - Midnight, Rocket
and Stan. Only time will tell what will happen with
our four eggs this year.
In the meantime, stay tuned to the website
(www.alcoa.com/falcons) for further developments
and the comings and goings of Sheila and Havoc.

OUR ENVIRONMENT AND OUR EMPLOYEE
Hi Mike, what prompted you to attend Greening
Australia’s Make an Impact workshop?
I wanted to find out if there were any new ideas and where I
should be concentrating my efforts for making my own
impact.
Have you made any changes at home to help reduce
your water and energy usage?
I have concentrated on water conservation by mulching
around trees and plants, and installing drip lines to them all.
The lines are connected to a water tank. I have also installed
a downpipe diverter to a wheelie bin which collects water to
drip feed my berry plantation.
What do you think of the overall program?
Greening Australia is doing a fantastic job by educating,
encouraging and helping everyone to get involved, which is
absolutely necessary for such a large scale project.
...MIKE ALLDEN
