Instead, our work involves lots of radio tracking, heaps
of walking around, and plenty of patience.
Here's some of the things that we do:
Intensive monitoring
Predator control
Intensive
Monitoring
Throughout the year we keep an eye on the birds from a distance,
using radio tracking technology.
Using a special radio receiver that picks up signals from
a radio transmitter attached to each bird, we work out the
approximate position of each bird every 7 days.
In between times, we do a quick 'Dead or Alive' check to
make sure the bird is still moving around - a sure sign that
it is still alive!
In the breeding season, we increase the frequency of this
monitoring to once every three days.
It requires long hours of patient searching, and means we
soon develop an intimate knowledge of our birds and their
hang outs.
"Nearly every little thing we do during the year is gearing
us up for a breeding season, knowing that if it occurs we
will be incredibly busy".
After locating the birds using radio tracking technology
and/or tracking dogs, we check their radio transmitter is
comfortable and replace its batteries, if necessary.
We also weigh the birds, check their moulting condition,
take blood samples, check for parasites, and sometimes take
their temperature.
All that information is loaded onto a national database,
which allows us to track and compare the life history of each
individual bird and to build up a picture of the species.
Predator Control
Brown Teal are almost biological refugees in their own land,
doomed to an exile on predator-free islands for the foreseeable
future. Those that do exist on the mainland are under constant
attack from mammalian predators, stoats, cats, ferrets, etc.
Just to keep them safe, we need to constantly safeguard our
Brown Teal areas from the threat of predator invasion
