I also collected 11 birds with a shotgun. We replaced the mist net over the hole & then tried to disturb the birds in the hole so that they would fly up into the net. A few did this but in general this wasn't very successful. The birds tend to bounce off the underside of the suspended net & not get caught even though the net was hanging as loose as possible.
