While this
isn’t about Kooka's, it did happen while I was waiting for them to arrive.
It was a
normal day, people jogging, walking babies, walking dogs.
Completely unaware what was going on right next to them.
There is a full on
battle being engaged.
And, it involved a number of species that usually hunt alone.
And, it was
done with military precision.
And, all knew
their exact roles.
The Players;
The first in
were the Australasian Grebes. As a tight bunch, 12 or so birds would drive the
fish towards the shore.
5 meters
behind them came the Cormorants.
5 meters
behind them came the heavy artillery, the Pelicans.
Behind them, more cormorants.
In the air
were the Terns & Gulls.
On land they were
faced with Egrets & White Faced herons.
But it was
how it worked that amazed me.

Pelican mob |
Let’s say the
Pelicans went in first.
They are slow & clumsy.
They would get a few fish - sure.
But the school would soon scatter
and it would all be over.
Now, look at the
way it was done, and the way it worked for everyone. No one group
reaped more than the other & all got a good feed.
The Strategy;
|
Sorry - poor photo - but they're small & 50 meters away (Australasian Grebes) |
The Grebes are first in. These guys are small,
fast and nimble. Their role is to panic the school & drive them towards shore. But these are small birds with small mouths. They can only take on the
smallest of fish. They get to pick off the panicked
fingerlings, while still driving the school. A lot get past them.

behind the Grebes came the Cormorants |
Cormorants –
bigger, not quite as nimble, but still bloody fast. They are the 2nd
prong to the attack. They sit back a bit. They turn around the fleeing fish, (while getting a feed).
The Grebes get a 2nd crack. All the while the school is getting
pushed into the shallows.
Those fish trying to bolt to the south were greeted with this.
|
pelican push |
Those fish that tried to walk on water, well, they got picked off by the Terns & Gulls.
In the
shallows, those that tried to walk on land had to face the Egrets &
Herons.
They got a feed while sending the school back towards the Grebes &
Cormorants. And don't forget the Pelicans.
