Cannon-netting
（重定向自Cannon net）
Cannon-netting is a method of catching large numbers of animals, often birds, usually to band them, or otherwise tag them, as well as acquiring biometric data (measurements), in order to find out about their movements, migration routes, survival rates and metabolism. It is often used where large numbers of birds, especially waders, terns and gulls aggregate on beaches at high tide, or in places (which may be baited) where waterfowl or cockatoos feed. Cannon-netting may be used as a capture-for-culling method for perceived pest species such as cockatoos. Mammals such as deer and macropods may also be cannon-netted.
