Bird watching

Birdwatching, or birding, is the observing of birds, either as a recreational activity or as a form of citizen science. A birdwatcher may observe by using their naked eye, by using a visual enhancement device such as binoculars or a telescope, by listening for bird sounds, watching public webcams, or by viewing smart bird feeder cameras.

Most birdwatchers pursue this activity for recreational or social reasons, unlike ornithologists, who engage in the study of birds using formal scientific methods.

Birding, birdwatching, and twitching

The first recorded use of the term ''birdwatcher'' was in 1712 by William Oldsworth. The term ''birding'' was also used for the practice of ''fowling'' or hunting with firearms as in Shakespeare's '' The Merry Wives of Windsor'' (1602): "She laments sir... her husband goes this morning a-birding." The terms ''birding'' and ''birdwatching'' are today used by some interchangeably, although some participants prefer ''birding'', partly because it includes the auditory aspects of enjoying birds.

In North America, many birders differentiate themselves from birdwatchers, and the term ''birder'' is unfamiliar to most lay people. At the most basic level, the distinction is perceived as one of dedication or intensity, though this is a subjective differentiation. Generally, self-described birders perceive themselves to be more versed in minutiae such as identification (aural and visual), molt, distribution, migration timing, and habitat usage. Whereas these dedicated ''birders'' may often travel specifically in search of birds, ''birdwatchers'' have been described by some enthusiasts as having a more limited scope, perhaps not venturing far from their own yards or local parks to view birds. Indeed, in 1969 a ''Birding Glossary'' appeared in '' Birding'' magazine which gave the following definitions:

''Twitching'' is a British term used to mean "the pursuit of a previously located rare bird." In North America, it is more often called ''chasing''. The term ''twitcher'', sometimes misapplied as a synonym for ''birder'', is reserved for those who travel long distances to see a rare bird that would then be ''ticked'', or counted on a list. The term originated in the 1950s, when it was used to describe the nervous behaviour of Howard Medhurst, a British birdwatcher. Earlier terms for those who chased rarities were ''pot-hunter'', ''tally-hunter'', or ''tick-hunter''. The main goal of twitching is often to accumulate species on one's lists. Some birders engage in competition to accumulate the longest species list. The act of the pursuit itself is referred to as a ''twitch'' or a ''chase''. A rare bird that stays long enough for people to see it is ''twitchable'' or ''chaseable''.

Twitching is highly developed in the United Kingdom, the Netherlands, Denmark, Ireland, Finland and Sweden. The size of these countries makes it possible to travel throughout them quickly and with relative ease. The most popular twitches in the UK have drawn large crowds; for example, approximately 2,500 people travelled to Kent, to view a golden-winged warbler (''Vermivora chrysoptera''), which is native to North America. Twitchers have developed their own vocabulary. For example, a twitcher who fails to see a rare bird has ''dipped out''; if other twitchers do see the bird, they may feel ''gripped off''. ''Suppression'' is the act of concealing news of a rare bird from other twitchers.

Many birders maintain a '' life list'', that is, a list of all of the species they have seen in their life, usually with details about the sighting such as date and location. The American Birding Association has specific rules about how a bird species may be documented and recorded in such a list if it is submitted to the ABA; however, the criteria for the personal recording of these lists are very subjective. Some birders "count" species they have identified audibly, while others only record species that they have identified visually. Some also maintain a ''country list'', ''state list'', ''county list'', ''yard list'', ''year list'', or any combination of these.

The history of birdwatching

The early interest in observing birds for their aesthetic rather than utilitarian (mainly food) value is traced to the late 18th century in the works of Gilbert White, Thomas Bewick, George Montagu and John Clare. The study of birds, and of natural history in general, became increasingly prevalent in Britain during the Victorian Era, often associated with collection, eggs and later skins being the artifacts of interest. Wealthy collectors made use of their contacts in the colonies to obtain specimens from around the world. It was only in the late 19th century that the call for bird protection led to the rising popularity of observations of living birds. The Audubon Society was started to protect birds from the growing trade in feathers in the United States while the Royal Society for the Protection of Birds began in Britain.

The phrase "bird watching" appeared for the first time as the title of the book ''Bird Watching'' by Edmund Selous in 1901. In North America, the identification of birds, once thought possible only by shooting, was made possible by the emergence of optics and field identification guides. The earliest field guide in the US was ''Birds through an Opera Glass'' (1889) by Florence Bailey.

Birding in North America was focused in the early and mid-20th century in the eastern seaboard region, and was influenced by the works of Ludlow Griscom and later Roger Tory Peterson. '' Bird Neighbors'' (1897) by Neltje Blanchan, an early birding book, sold over 250,000 copies. It was illustrated with color photographs of stuffed birds.

The organization and networking of those interested in birds began through organizations like the Audubon Society, which was against the killing of birds, and the American Ornithologists' Union (AOU). The availability of first the bicycle and then the car increased the mobility of birdwatchers and this made new locations accessible. Networks of birdwatchers in the UK began to form in the late 1930s under the British Trust for Ornithology (BTO). The BTO saw the potential to produce scientific results through the networks, unlike the Royal Society for the Protection of Birds (RSPB) which like the Audubon Society originated from the bird protection movement.

Like the AOU in North America, the BOU had a focus mainly on collection-based taxonomy. The BOU changed focus to ecology and behaviour only in the 1940s. The BTO movement towards 'organized birdwatching' was opposed by the RSPB, which claimed that the 'scientification' of the pastime was 'undesirable'. This stand was to change only in 1936 when the RSPB was taken over by Tom Harrisson and others. Harrisson was instrumental in the organization of pioneering surveys of the great crested grebe.

Increased mobility of birdwatchers ensured that books like ''Where to Watch Birds'' by John Gooders became best-sellers. By the 1960s air travel became feasible and long-distance holiday destinations opened up. By 1965, Britain's first birding tour company, ''Ornitholidays'' had been started by Lawrence Holloway. Travelling far away also led to problems in name usage: British birds such as "wheatear", "heron" and "swallow" needed adjectives to differentiate them in places where there were several related species. The falling cost of air travel made flying to remote birding destinations a possibility for a large number of people towards the 1980s. The need for global guides to birds increased, and one of the biggest resulting projects was the ''Handbook of the Birds of the World'', begun in the 1990s by Josep del Hoyo, Jordi Sargatal, David A. Christie, and ornithologist Andy Elliott.

Initially, birdwatching was largely restricted to developed countries such as the United Kingdom and the United States of America. Since the second half of the 20th century an increasing number of people in developing countries have engaged in this activity, such as in the Degua Tembien district of Ethiopia. Transnational birding has played an important role in this, as birders in developing countries usually take up the pastime under the influence of foreign cultures with a history of birding. A majority of transnational birders are middle-aged, male, affluent, and belong to the Anglophone countries or Scandinavia.

Economic and environmental impact

In the 20th century, most of the birding activity in North America was done on the east coast. The publication of Roger Tory Peterson's field guide in 1934 led to the initial increase in birding. Binoculars, an essential piece of birding equipment, became more easily available after World War II, making the hobby more accessible. The practice of travelling long distances to see rare bird species was aided by the availability of cars and their associated infrastructure. Nevertheless, distance to urban centres may still affect number of birdwatchers participating in observations of rare bird species. About 4% of North Americans were interested in birding in the 1970s, and in the mid-1980s at least 11% were found to watch birds at least 20 days of the year. The number of birders was estimated at 61 million in the late 1980s. The income level of birders has been found to be well above average.

''The Sibley Guide to Birds'', published in 2000, had sold 500,000 copies by 2002. It was found that the number of birdwatchers rose, but there appeared to be a drop in birdwatching in the backyard.

According to a U.S. Fish and Wildlife Service study, birders contributed $36 billion to the US economy in 2006, and one fifth (20%) of all Americans are identified as birdwatchers. According to the U.S. Fish and Wildlife Service in 2016, over 45 million Americans consider themselves birders.

North American birders were estimated to have spent as much as US$32 billion in 2001. The spending is on the rise around the world. Kuşcenneti National Park (KNP) at Lake Manyas, a Ramsar site
