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.
