peregrine falcons
For the third year in a row, Peregrine Falcons have
returned to Alcoa Anglesea to the nest box on top
of the water tower.
Despite laying four eggs this year, only one egg
successfully hatched. Whilst there is no
explanation for why this happened at Anglesea in
particular, there are several reasons why an egg
may not hatch - parents may be incompatible or a
parent may have left the nest during a storm
resulting in a drop in incubation temperture of the
eggs. Both of these scenarios appear unlikely for
Anglesea (parents bred successfully in 2005, no
rainstorms lately!!) and the presence of unhatched
eggs at other nests across the state this year
suggests the cause is wider spread and may be
the consequence of drought conditions.
In late October, volunteers from the Victorian
Peregrine Project took the travel tower to the
elevated home to check the chicks’ health,
measurements and banding. Weighing in at 870g,
it was confirmed Uno is one healthy chick.
One of the positives for having one chick instead of
four is the amount of food the chick receives
without any sibling competition. The more food
Uno receives, the stronger she will be giving her a
better chance of survival.
Grade 1 students from Anglesea Primary School
and members of ANGAIR witnessed the banding
and naming of the bird, with the name ‘Uno’
chosen, referring to the number one.
The other exciting Peregrine Falcon news for 2006
is the Alcoa Anglesea webcam.
In a Victorian first, Alcoa Anglesea has provided a
window in to the world of Peregrine Falcons by
installing a webcam on the water tower near the
nestbox and is broadcasting the images over the
internet.
The webcam at www.alcoa.com/falcons will
provide a new view of day-to-day life in the
Peregrine Falcon nest,with images refreshing at
one minute intervals.

OUR ENVIRONMENT AND OUR EMPLOYEES..
V ictor
ictorian Per
egrine Pr
oject
ictor,, how important is the V
Victorian
Peregrine
Project
for the conservation of the Peregrine Falcon in Victoria?
Very important. The project has just been acknowledged at a
international conference in Mexico as the most extensive volunteer
program in the world for the Peregrine Falcon, both in it’s scope of
yearly activities and how long it has been running (16 years).
That must be nice to hear after year’
s of personal
year’s
dedication and effort?
It certainly is. It’s great that the program has been recognised at an
international level.
How important is the nest box at Alcoa Anglesea?
The use of artificial nest boxes such as the one at Alcoa Anglesea
suggests that the natural nest sites for Peregrine Falcons are at
saturation level or that there simply isn’t enough natural nest sites to
go around. As more natural nest sites along the coast are lost to
development and human disturbance, the more critical these artificial
sites become to the future of the Peregrine Falcons.
How does the future look for the Peregrine Falcon?
We were lucky in Australia that the Peregrine Falcon population didn’t
decline as far as populations in other parts of the world in the 60’s
and 70’s. The agriculture in Australia was less intensive and the use of
pesticides such as DDT was not as widespread. This has enabled the
Peregrine Falcon populations in Australia to recover more quickly.
