ANGLESEA ENVIRONMENT REPORT OCTOBER 2008
peregrine falcons
We are proud to announce Alcoa Anglesea’s three
falcon chicks for 2008; Midnight, Rocket and Stan.
For the fifth year in a row, Peregrine Falcons have
returned to the purpose-built nesting box on top
of the Alcoa Anglesea water tower.
After less than 50% of the eggs hatching in 2006
and 2007, it was a welcome sight to have all three
eggs successfully hatch this year and see three
bundles of white fluff eagerly waiting for us as we
approached the nest box.
Not so eager to see us were the protective
parents, Sheila and Havoc. They certainly made
their presence known during the expedition up to
retrieve the chicks. The visit was quick as both
were relentless in their swooping (and striking)
behaviour. Chin straps are no longer optional!
Volunteers from the Victorian Peregrine Project
completed the health assessment and banding of
the chicks. At this age, weight and wing length
measurements are used to determine the sex of
the chicks with males typically one-third smaller
than females. This year we have three healthy
boys with Midnight, Rocket and Stan weighing in
at 590, 575 and 560g respectively. With no
distinguishable size difference between the three,
the unique code combination on the two-tone
aluminium band on their right leg is the only
definitive way to tell who’s who.
Grade 2 students for the Anglesea Primary School
were on the ground to witness the measurement,
health check and banding of the three male chicks.
Three students - Myee, Klara and Emily - had their
suggestions for the chicks’ names chosen from
the class list.
The webcam at www.alcoa.com/falcons continues
to broadcast images from the Peregrine Falcon
nest box at Alcoa Anglesea over the internet.
Weekly highlights are posted on the website
showing the adventures of Midnight, Rocket and
Stan as they prepare to leave the nest for the
wider world.

OUR ENVIRONMENT AND OUR EMPLOYEE
Hey Peter, the Peregrine Falcons sure have taking a liking
to staff from the Control Room?
They certainly have! What started off a couple of years ago with
employees getting a gentle fright as a falcon swooped by, has
escalated in the last two years with Sheila fiercely defending her
territory with repeated strikes to hard hats!
A new solution has been trialled this year, is it working?
The solution was to install an avenue of flags that would provide
cover for employees to freely walk under whilst providing a visual
obstacle that the Peregrines will avoid. The east side of the 7th
floor facing the nest box was considered the most exposed so
was chosen for the trial. The flags are working well at this
location. However the flags aren’t everywhere so employees are
still vulnerable on other parts of the Station.
So what will happen now?
Operators from the control room are marking on a map where the
swooping and strikes are occuring. Hopefully this will lead to the
identification of hot-spots where we can look at either extending
the flags or investigating other options to protect our employees.
