Observation or identification of wild birds in their natural habitat. Basic equipment includes binoculars, a field guide to aid identification, and a notebook for recording time and place of sightings. The lists of bird observations compiled by members of local bird-watching societies are often useful to scientists in determining dispersal, habitat, and migration patterns of the various species. Bird-watching is primarily a 20th-century phenomenon; before 1900 most students of birds had to shoot them in order to identify them. Its popularity grew through the publication of journals and books, in particular the field guides (beginning in 1934) of Roger Tory Peterson.

Birdwatching or birding is the observation and study of birds with the naked eye or through a visual enhancement device like binoculars. Birding often involves a significant auditory component, as many bird species are more readily detected and identified by ear than by eye. Most birdwatchers pursue this activity mainly for recreational or social reasons, unlike ornithologists, who engage in the study of birds using more formal scientific methods.
The term "twitcher" was however reserved for those who travelled long distances just to see a rare bird that would be "ticked" off on a "list". The usage of the term twitcher began in the 1950s originating from a phrase used to describe the nervous behaviour of Howard Medhurst, a British birdwatcher. Prior to that the term used for those who chased rarities was "pot-hunter", "tally-hunter", "tick-hunter" or "tick-hunter". The practice of travelling long distances to spot rarities was aided by the rising popularity of cars.
The goal of twitching is often to accumulate species on one's lists. Some birders engage in competition with one another 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 put long enough for people to see it is called "twitchable" or "chaseable".
Twitching is highly developed in the United Kingdom, the Netherlands, Denmark, Ireland, Finland and Sweden. The smaller regional size of these countries make it possible to quickly travel inside their borders with relative ease. The most popular twitches in the UK have drawn large crowds, such as a group of approximately 5,000 people who came to view a Golden-winged Warbler in Kent. 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, he may feel gripped off. Suppression is the act of concealing news of a rare bird from other twitchers.
The organization and networking of those interested in birds began through organizations like the Audubon Society that was against the killing of birds and the American Ornithologists' Union (AOU). The rising popularity of the car increased the mobility of birdwatchers and this made new locations accessible to those interested in birds. Networks of birdwatchers in the UK began to form in the late 1930s under the British Trust for Ornithology. The BTO saw the potential to produce scientific results through the networks, unlike the Royal Society for the Preservation of Birds (RSPB) which like the Audubon Society originated from the bird protection movement. Like the AOU in the US, the BOU had a focus mainly in 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 and by 1965, Britain's first birding tour company, Ornitholidays was started by Lawrence Holloway. Travelling far away also led to problems in name usage, British birds like "Wheatear", "Heron" and "Swallow" needed adjectives to differentiate them in places where there were several related species. The need for global guides to birds became more relevant and one of the biggest projects that began was the "Handbook of the Birds of the World" which started in the 1990s with Josep del Hoyo a country doctor in Catalonia, Jordi Sargatal and ornithologist Andy Elliott.
The falling cost of air-travel made flying to remote birding destinations a possibility for a large number of people towards the 1980s.
About 4% of 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. Kellert An estimate of 61 million birders was made in the late 1980s. Leary The income level of birders has been found to be well above average.
American birders were estimated to have spent as much as USD 32 billion in 2001. The spending is on the rise around the world. Kuşcenneti National Park (KNP) at Lake Manyas, a Ramsar site in Turkey was estimated to attract birders who spent as much as 103,320,074 USD annually. Guided bird tours have become a major business with at least 127 companies offering tours worldwide. An average trip to a less-developed country costs $4000 per person and includes about 12 participants for each of 150 trips a year. It has been suggested that this economic potential needs to be tapped for conservation.
Most birdwatchers will keep an eye on birds around them at all times but will make specific trips to observe birds fulltime. The most active times of the year for birding in temperate zones are during the spring or fall migrations when the greatest variety of birds may be seen. On these occasions, large numbers of birds travel north or south to wintering or nesting locations. Early mornings are typically better as the birds are more active and vocal making them easier to spot.
Certain locations such as the local patch of forest, wetland and coast may be favoured according to the location and season. Seawatching is a type of birdwatching where observers based at a coastal watch point, such as a headland, watch birds flying over the sea. This is one form of pelagic birding, by which pelagic bird species are viewed. Another way birders view pelagic species is from seagoing vessels.
Weather plays an important role in the occurrence of rare birds. In Britain, suitable wind conditions may lead to drift migration, and an influx of birds from the east. In America, birds caught in the tail-end of a hurricane may be blown inland.
Many birders take part in censuses of bird populations and migratory patterns which are sometimes specific to individual species. These birders may also count all birds in a given area, as in the Christmas Bird Count or follow carefully designed study protocols. This kind of citizen science can assist in identifying environmental threats to the well-being of birds or, conversely, in assessing outcomes of environmental management initiatives intended to ensure the survival of at-risk species or encourage the breeding of species for aesthetic or ecological reasons. This more scientific side of the hobby is an aspect of ornithology, coordinated in the UK by the British Trust for Ornithology.
Some competitive birding events include:
Equipment commonly used for birding includes binoculars, a spotting scope with tripod, a notepad, and one or more field guides. Hides or observation towers are often used to conceal the observers from birds, and/or to improve viewing conditions. Over the years optics manufacturers have learned that birding binoculars sell, and virtually all have specific binoculars for just that. Some have even geared their whole brand to birders.
allow users to observe and photograph birds over the web; similarly, robotic cameras set up in largely inhospitable areas are being used to attempt the first photographs of the rare Ivory-billed Woodpecker. These systems represent new technologies in the birdwatcher's toolkit.
With the advent of the World-Wide Web, birders have been using the internet to convey information; this can be via mailing lists, forums, bulletin-boards, web-based databases and other media. While most birding lists are geographic in scope, there are special-interest lists that cater to bird-identification, 'twitchers', seabirds and raptor enthusiasts to name but a few. Messages can range from the serious to trivial, notifying others of rarities, questioning the taxonomy or identification of a species, discussing field guides and other resources, asking for advice and guidance, or organizing groups to help save habitats. Occasional postings are mentioned in academic journals and therefore can be a valuable resource for professional and amateur birders alike. One of the oldest, Birdchat
(based in the US) has probably got the most subscribers, followed by the English-language fork of Eurobirdnet

Other minority groups have formed organizations to support fellow birders and these include the Gay birders and the Disabled Birders Association.
The study of birdwatching has been of interest to students of the sociology of science.
Birdwatching literature, field guides and television programs have been popularized by birders like Pete Dunne and Bill Oddie.
