Born
on one of the highest Perth Hills Wedge-tailed Eagle eyries that I've
ever had the privilege (or punishment!) of
climbing, the female eaglet I
am holding above was one of 18 that were captured and marked for my
research this year. When I fitted her rings/bands and took measurements
earlier in the season, I left a climbing rope in place in order to be
able to access the nest again, and yesterday the time had come to do
just that, to fit her with a GPS/Satellite transmitter. This particular
transmitter was sponsored by
Tronox,
a titanium company operating on a mineral sand mine just north of
Perth. I have fond memories of visiting the 'Cooljarloo' mine for fauna
survey work with
Bamford Consulting Ecologists, not long after I finished uni over ten years ago. Connections were again forged with Tronox through Bob Huston from the
Department of Biodiversity, Conservation and Attractions,
who has provided amazing support for my eagle research in recent years.
Together with property owner John Ffarrington (who kindly gave me
access to search for eagles on his Gidgegannup land), Ieva Tomsons from
the Toodyay Herald newspaper, and my dear Dad (who was yet to experience
an eagle banding activity), our little 'tagging team' set off on a
fabulous Noongar Country afternoon to deploy the transmitter.

After scaling the very tall Wandoo
nest-tree and lowering the eaglet down in a handling bag, it was time to
fit the transmitter using the 'backpack' mount method I learned from
friends and raptor researcher mentors Ewan and Jenny in Scotland. I was
very fortunate to have my friend and fellow environmental scientist
Andrew Moore along to help by holding the eagle, who turned out to be quite a handful!

Although she had been fitted with a
falconry hood, which normally blinds (and
subsequently calms) the bird, this eagle must have been able to see
through a crack in the eye slots, as she persistently bit my hands and
fingers while I carried out the attachment procedure. The main concern
when handling eagles is their powerful talons, which in juveniles are
pin-sharp, and together with extremely powerful 'ratcheted' toe/foot
muscles, can inflict severe injuries. The bill is more of a 'tearing
tool' and has far less power than a foot, but it does have a very sharp
tip, useful for tearing apart kangaroo flesh, so it can still hurt!
 |
| Ouch! Not as bad as a talon though! |
Fortunately Chris Bean
from Tronox, who had been taking many wonderful photos of the occasion,
stepped in to calmly support the eaglet's head which eased the
beak-attacks on my hands! I could then carry on with the fitting the harness in relative peace.

After about half an hour of fine-tuning
the transmitter harness fit, stitching it with a 'weak link' that will
eventually fall off with natural decay, and taking a few updated
measurements of the eagle's wings and feet, it was time to return her to
the nest. I ascended into the canopy, gently removed her from the
handling bag, and she hopped out in a slightly frustrated manner, but
seemed relieved to be free to move about again.
Looking
back at an eyrie and seeing a young Wedge-tailed Eagle safely back
'home' after it has been marked for research, and knowing we will be
able to follow its journey, evokes a very unique feeling in me. It is
mainly one of excitement and intrigue but also satisfaction (especially
after such an adrenalin-induced tree-climb!) and a very strong element
of concern for the bird, knowing it will soon leave the safety of its
nest and venture further out into this dangerous world.

Although I'd been bitten by eagles quite a
few times before, I certainly
hadn't experienced a bird who bit so persistently, and this behaviour
prompted me to suggest the name 'Baakininy', which in Noongar language
means
'biting'. I was very pleased that Chris and the Tronox team also
thought this to be appropriate. While I haven't traditionally been into
naming wild animals, I believe it is important as a scientist to create
an identify for the individual animals we are researching, particularly
those whose progress we are able to follow in the close detail
satellite-tracking allows. As an ambassador for Australia wildlife, the
ecosystems of which it is a part, and the ancient cultural connection
that
Aboriginal People have shared with this amazing landscape, I have chosen
to use
indigenous language (Noongar in South-west Western Australia, and Martu
in
the Wiluna area) for Wedge-tailed Eagle names, because I feel it serves
to remind us that these animals have been observed by people for
thousands of years. These people are in some places in danger of losing
their cultures, which are intricately linked with the lives of native
animals
and very much on the same page as 'western' values of biodiversity
conservation (modernly referred to as 'Caring for Country'). Of course,
such languages may provide us 'whitefellas' with new pronunciation
challenges, but learning anything new always seems more difficult at
first, and
what better way to continue the use of an ancient language than by
speaking out loud names given to charismatic, majestic birds of prey!?
The
day was an extremely memorable one, and I am so grateful to all those
who took part for their support, assistance and encouragement. We'll be
excited to watch Baakininy's progress with eagle eyes!
