ANGLESEA ENVIRONMENT REPORT OCTOBER 2007
peregrine falcons
We are proud to formally introduce Dash and
Concorde, Alcoa Anglesea’s falcon chicks for 2007.
The names for our falcon chicks were nominated by
students from Anglesea Primary School.
For the fourth year in a row, Peregrine Falcons
have returned to Alcoa Anglesea to the nest box
on top of the water tower. However, despite
laying four eggs, only two have successfully
hatched. Whilst there is no explanation for why
this has happened, a similar scenario occurred
here last year with only one of the four eggs
hatching successfully. There are several reasons
why an egg may not hatch - drought, adults may
be incompatible or an adult may have left the eggs
resulting in a drop in incubation temperature.
The positive for having two chicks instead of four
is the amount of food each chick receives with less
sibling competition. The more food the two chicks
receive, the stronger they will be, giving them a
better chance of survival. This extra benefit was
clearly evident when volunteers from the Victorian
Peregrine Project took the travel tower to the
elevated home this month to check on the chicks.
Weighing in at a very healthy 905g is our female,
Dash, with all the characteristics to be as
formidable as her mother. More reserved and
weighing in at 590g is our male, Concorde.
Sheila made her presence felt during the expedition
up to retrieve the chicks - the hard hats were
essential PPE under the circumstances! Whilst
both parents exhibited agitated behaviour Sheila
didn’t hesitate on getting a close look at the bright
yellow duco of our hats. The health assessment
and banding of the chicks was completed and the
chicks returned to the nest box as quickly as
possible so that the parents could rest easy.
The webcam at www.alcoa.com/falcons continues
to broadcast images from the Peregrine Falcon
nest box at Alcoa Anglesea over the internet.
There’s been plenty of action and more to come as
Dash and Concorde continue to grow, change
plumage and learn to fly. Regular updates are also
included on the website on highlights of the week.

OUR ENVIRONMENT AND OUR EMPLOYEES..
Gary
Gary,, we believe you witnessed the banding of the
falcon chicks. What happened? It was very interesting (and
noisy). The chicks were retrieved from their nest box on the
water tower which did not please the adults. It was however very
amusing for the onlookers seeing the handlers swooped and
collected by the parents. The helmets did come in handy! The
chicks were then brought to the store where the banding and
data recording took place.
Any ideas what the banding is about? The chicks were
banded for research purposes to determine how far they disperse
and so they can recognise where they came from.
Any difference between the two chicks? The chicks are
now adorned with their own uniquely coded jewellery, which
apparently looks cool if you are a falcon. I was told that the
larger of the two is the female and not surprisingly the loudest.
How was the experience? It was interesting to learn that the
chicks are banded at three weeks to coincide with their skeletal
structure being fully developed. All in all it was a great experience to feel the down of the chicks which was incredibly soft
and to appreciate the sheer strength of these powerful birds and
their amazing talons.
