Mist nets are used by ornithologists and bat biologists to capture wild birds and bats for banding or other research projects. Mist nets are typically made of nylon or polyester mesh suspended between two poles, resembling a volleyball net.

When properly deployed in the correct habitat, the nets are virtually invisible. Mist nets have shelves created by horizontally strung lines that create a loose, baggy pocket. When a bird or bat hits the net, it falls into this pocket, where it becomes tangled.

The purchase and use of mist nets require permits, which vary according to a country or state's wildlife regulations. Mist net handling requires skill to optimally place the nets, avoid entangling nets in vegetation, and properly store nets.
