Pigeon shooting is a type of live bird wing shooting competition. Traditionally, there are two types of competition: box birds and columbaire. In box birds, the pigeons are held in a mechanical device that releases them when the shooter calls out. In columbaire, the birds are hand thrown by a person when called upon. The pigeons are bred for speed. The most common species of pigeon used in regulated shooting contests is known as a zurito (Columba oenas). In the shooting competition, large sums of money are gambled and winners can have purses exceeding US$50,000. The equipment for the sport can be specialized and purpose-built. In the past, the sport was popular worldwide. It was primarily a sport of the upper class and was held at resort locations such as Monaco and Havana. Popular magazines have covered the sport—for example, Field & Stream and Sports Illustrated But, over time, the sport has fallen out of widespread favor due to costs, alternative shooting sports such as trap shooting, skeet shooting, and sporting clays, and animal rights activism over a blood sport. Proponents of the sport argue that live pigeons are more challenging to shoot than clay targets. Many claim that pigeon shoots are no more cruel than extermination efforts carried out in cities where feral pigeons are considered a nuisance and are often controlled using lethal methods. The United States Department of Agriculture euthanizes over 60,000 pigeons a year in response to complaints. In the past, events used to be publicly posted. The sport still exists in pockets around the world, but generally, it is not well publicized and it is only hosted in select locations, such as private gun clubs typically by invitation only. In the United States live pigeon shoots have been held on large privately owned ranches and plantations in the South. Usually, this is to avoid the attention of protesters inevitably attracted by the events. Animal rights activists have begun deploying drones in an attempt to disrupt live pigeon competitions. In the past, U.S. Senator Jim Inhofe held annual live pigeon shoots in Oklahoma as part of a political fundraiser. In 2015 a drone operated by an animal rights group was shot down while flying over Inhofe's fundraiser that was being held at a remote ranch. In 2017 due to protests from animal rights groups Inhofe replaced his annual live pigeon shoot with a wild dove hunt.
