Require a licence to purchase/install bird spikes and netting

House Sparrow, House Martin, Swift, Swallow, Starling, Herring Gull and other bird species associated with urban environments have undergone catastrophic population declines in recent decades. We believe the widespread introduction of physical barriers to nesting and roosting have contributed to these unsustainable declines. There are also animal welfare concerns, as birds can become trapped and die in nets. In those cases where the use of such technology can be justified a Government licensing should operate.
