MynaVac Trap
This is a device for trapping mynas breeding in a
nestbox. While effective, it is no longer offered for a number
of reasons. First, it is not very efficient in that only a
single bird is caught at a time. Second, it is inconvenient in
that it must be done at night. Finally, it is not a
cost-effective purchase for someone who has only a nestbox or
two. But it is a simple device that can be easily made and it
could be useful in a backyard situation. Information on how to
make and use it is therefore provided.
The bulk of the device consists
of 200mm of 90mm PVC downpipe fitted with a standard 90° bend.
The photo shows a plate on the top side of the bend but that is
necessary only where the entrance hole is very large. The net at
the bottom is a standard prawn net held on with an O-clamp.
There are some eye screws fitted to the back of the pipe to take a
stiff piece of wire that is fitted to a long stick. The stick
will also need a guide to stop the trap rolling side to side. A
second stick is required, also fitted with a stiff wire, to dislodge
the bird.
The intention is to trap a female Indian myna while she is sitting on eggs
or chicks in a nestbox. Mynas are normally very skittish birds,
making them difficult to trap during the day. However, another
characteristic is that the female sits very tight on eggs during the
night, hence trapping is done at night.
To use, lift the trap and hold it over
the entrance of the box. Insert the wire of the other stick into
one of the drainage holes of the nestbox and mve it up and down
vigorously (a second person is best). The bird will fly into the
trap and get caught in the net.
Often the male will immediately bring another female back to the box, allowing
the possibility of trapping
multiple females in quick succession. In one situation, 3 females were trapped in one box
over a period of 6 weeks.
