peregrine falcons
We are proud to formally introduce Froona,
Warrun and Barega, Alcoa Anglesea’s falcon
chicks for 2009. For the sixth year in a row,
Peregrine Falcons have returned to Alcoa
Anglesea to the nest box on top of the water
tower. The nest box was moved to the opposite
side of the tower earlier this year, and luckily Sheila
was happy enough with her new home to lay four
eggs.
However, only three of the four eggs hatched
successfully this year. A similar event occurred in
both 2006 and 2007 with only one and two out of
four eggs hatching, respectively. 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.
Suggestions of names for our new additions came
from all over the world. Our female chick is named
Froona to recognise Froona Veldhuis from the
Netherlands, a devoted advocate for the Peregrine
Falcon, who died in April this year. Our two boys
have been named Barega and Warrun. Both
names are from the Aboriginal language meaning
‘the wind’ and ‘the sky’ respectively.
We had three attempts to schedule the banding of
the falcon chicks. However, after forecast high
winds and the travel tower being involved in a
traffic accident (!), we were forced to cancel our
scheduled banding for 2009.
This left the webcam followers to determine the
sex of the three chicks. Male and female chicks
usually look very similar, with the size difference
being used to determine sex. The female chicks
are usually noticeably larger. The general consensus was that we had one female and two male
chicks, so the birds were named accordingly.
The two boys flew the coop much sooner than
their sister, however Froona did eventually fledge.
This has left us with a web cam (www.alcoa.com/
falcons) that is more often that not looking at an
empty nest box.
The web cam will shortly be switched off. We
hope you have enjoyed the 2009 season on the
web. If you have any feedback on the information
and images we have provided this year, please
contact us at [email protected]

OUR ENVIRONMENT AND OUR EMPLOYEE
Hi Elise, you have been our ‘webcam operator’ since it was
installed in 2006. What does this work involve?
I started posting regular updates in 2007 following the activities in
the nest box during the breeding season. We have huge
international interest in our falcons, so often when viewers log on
the webcam is under the cover of darkness. The blog and still
photos have proven a great way of keeping these viewers up to
date. This year a dedicated email address was introduced to
answer any enquiries from the website and so far we have had
over 200 emails and my role was to answer them if requried.
Have you had any other involvement with the Peregrine
Falcons at Alcoa Anglesea?
When the Peregrine Falcons returned to Alcoa Anglesea in 2003,
the initial work involved luring the falcons away from the station
with the installation of the nest box, monitoring the falcons,
education for our employees and liaison with the Victorian
Peregrine Project (VPP) for research/banding. Today the webcam
has made the monitoring easier, but the other work continues as I
advocate for the conservation of the internationally protected
species at our site.
Thanks Elise - we know where to come when we want our
Peregrine Falcon questions answered!
...ELISE JEFFERY
