Rocket nets and cannon nets are types of animal traps used to trap many live animals, usually birds, but they also have been used to catch large animals such as various species of deer. Rocket nets, cannon nets, and other net launching devices are built upon similar principles have been used since the 1950s (Dill and Thornsberry 1950, Hawkins ...
An animal caught in a mist net becomes entangled, so the net must be checked often and the animal removed promptly. Disentangling an animal from a mist net can be difficult and must be done carefully by trained personnel. If an animal is heavily entangled, the mist net may need to be cut to avoid injuring the animal, damaging the material.
Camera trapping is a method for recording wild animals when researchers are not present, and has been used in ecological research for decades. In addition to applications in hunting and wildlife viewing, research applications include studies of nest ecology , detection of rare species, estimation of population size and species richness, and ...
Mist nets are fine nets that are suitable for capturing birds in woodlands. The fine net is strung across trees so as to lie in the flight path of a bird. A bird flies into the nearly invisible net and falls to a fold at the bottom of the net where it usually gets entangled. These nets are used especially in bird ringing and are typically never ...
The Garmin Dash Cam 57 has been on the market for a couple of years, but it still stands out as an appealing option for drivers who want a small and straightforward video capture setup. Recording ...
The Sherman trap is a box-style animal trap designed for the live capture of small mammals. It was invented by Dr. H. B. Sherman in the 1920s and became commercially available in 1955. Since that time, the Sherman trap has been used extensively by researchers in the biological sciences for capturing animals such as mice, voles, shrews, and ...
Birds can be captured by hand, using mist-nets, cannon-nets, or cage traps. A band that is typically made out of aluminum, or coloured plastic is attached to the leg of the bird. Each band has a unique identification code so that when birds are later recaptured, individuals can be identified. [ 2 ]
A "SMART" drum line is based on the traditional drum line design, but it includes technology that can alert rangers to the capture of marine life, who can then attend the device if sea conditions permit. In Reunion, fishermen usually attend the drum lines within 90 minutes of an alert and 90 per cent of animals caught on the hooks survive. [53]
