People
said I was mad to start such an impossible project as on Grey Falcons.
No use denying the madness. Impossible!, oh no, by no means, far from
it. It's more that progress in such a project comes in small steps –
very, very small steps, one at a time, and a lot of time in between
steps, sometimes years.
The
lucky day when I captured a Grey Falcon was the culmination of five
years of endeavour in the project, or five years of failures you might
say. Same thing. Six days prior to that lucky day I had arrived at the
site. Since 2003 that site was known to me as the regular roost of a
pair of Grey Falcons. This year, 2009, I was back.
Day
1. Early morning. All was quiet. Eventually I became aware of a single
adult Grey Falcon, a female by size, dozing on what turned out to be her
favourite perch. My first catching attempt: - a classic Bal-Chatri with
a dead Budgerigar inside. Not the ideal set-up, but the Budgie was
suspended on fine thread from the ceiling of the Bal-Chatri cage and
moved by the wind. On that day the wind was just perfect. Budgies are a
favourite prey of Grey Falcons. The female didn't even acknowledge its
presence. At 8:30 am, a Hobby flew low over my low-cost pet, one brief
glance was all it earned. At 9 am, 'my' female flew off, to not
return before 5 pm. 9 to 5, makes sense. Plenty of time for me to come
up with a different trick: the Budgie dangling in the wind underneath a
mist-net, 6 x 2.6 m, 100 mm mesh, 210 denier, a modified Dho
Ghazi.
A
light breeze, temperature below 30˚C, simply perfect. Same reaction
as in the morning. Must be beer-o-clock.
Day
2. The Bal-Chatri with a stuffed Crested Pigeon (thanks to Helen
Macarthur), plus mist-net behind it, i.e. down-wind of the Bal-Chatri.
Sit and wait. A flock of Cockatiel flew past, their calling made the
female turn her head. Well, if she reacts to calls, I was prepared for
that. However, by the time I had set up the speakers etc. it was 9 am
and she was off. Maybe I would have more luck that afternoon. No. She
worked overtime at the office today. It was almost dark when she settled
on her favourite perch with a full crop and blood on the tip of the
bill.
Day
3. Mist-net with a dangling Ringneck, playback of excited Yellow-throated
Miners that I had recorded the evening before (using a mounted Barking
Owl to get the miners going). The female turned her head, looked in the
right direction but into the very far distance. Soon it was 9 am. What
next? Wind. The afternoon saw me picking leaves, twigs, prickles and
debris from the net that had blown over. The Ringneck had lost its head,
again.
Day
4. Dust-storm, and 42˚C. Sydney airport closed. So what? Grey Falcon
catching on hold.
I
finished reading Jane Austen's Sense
and Sensibility. I didn't like it; it's the title I guess. No
beer-o-clock tonight, the fridge had flattened one of the two vehicle
batteries last night.
Day
5. Clouds. The station manager had warned me “10 mls (of rain) and you
bog a duck.” “Then”, I said, “I would simply stay put for a
couple of days”. He laughed: “You would be there for weeks. We'll
fly you out”. Luck for once was on my side as the rain held off.
Catching
time again. My latest idea - that female would be looking for a mate. So
I got out a plastic Grey Falcon. Well, when I bought it it was a
Peregrine, advertised as garden ornament. Weird. I had re-painted it to
be an adult Grey Falcon, what else. That decoy, plus play-back of Grey
Falcon calls that I had recorded a couple of years ago in Queensland,
and with no wind. Plus two mist-nets, in a dog-leg around the decoy.
Down she came, low and slow, almost touching the plastic companion. Only
the length of the speaker cable away from me, standing there in full
view. Incredibly she managed to pull up just in front of the net, turned
around, came back from the other side, up and over the net. Saw the net,
learned the trick. Any ideas?
In
the afternoon it was above 35˚C. Of all the conditions of the two
dozen permits for the project, that's a sensible one - no catching when
the temperature reaches 35˚C. The last book I had with me is by
Dostoevsky, The Idiot. I feel
better.
Day
6. The weather was cooperative again, a light breeze, high twenties,
hardly any flies. Alas I had run out of ideas. Live bait sure would
work, I have no doubt, but animal ethics committees consider 'birding'
to be essentially different from 'fishing'. Even driving around in that
sort of temperature with a cage full of budgies in the back of the car
would be hazardous.
Then
I saw her, flying low right towards me, prey in her talons. Without
knowing what I did and why, I jumped up and ran after her. She dropped
the prey, a Peaceful Dove. Very peaceful it was indeed, but complete
with head and wings and tail, only a little blood on the neck. I picked
it up, ran back to the car. Out came the cage trap with the flap door,
in with the dove, door release mechanism activated. Soon the falcon
returned to her prey, landed near the trap, walked around, in she went.
Door closing. Got her!!. I ran, but just before I reached the trap she
had forced herself through a tiny gap, breaking a joint in the metal
mesh of the door. Gone. It doesn't help to repeat my comment.
I
took the dove out, ready to declare defeat. Then another brilliant idea.
The top of the trap was fitted with nooses, the result of an early
lesson I had to learn years ago in Broome. On that occasion I had tried
to catch a Great Bowerbird. I had pinched an item from its bower and had
put it inside the trap, door open. The bowerbird however didn't go into
the trap but jumped onto the roof, causing the door to shut and the
Bowerbird to fly away. It was then that I came up with the nooses on the
top of the trap.
Back
to the female Grey Falcon. I tied the dove onto the top of the trap.
Down she came, onto the trap, feeding. My breathing stopped. Only after
she had finished eating did she and I realize that she was caught by one
toe in one noose.
The rest was a piece of cake.
