Finland Equipment commonly used for birding includes
binoculars, a
spotting scope with
tripod, a
smartphone, a notepad, and one or more
field guides. Hides (known as
blinds in North America) or observation towers are often used to conceal the observers from birds, and/or to improve viewing conditions. Virtually all optics manufacturers offer specific binoculars for birding, and some have even geared their whole brand to birders.
Sound equipment Recognition of
bird vocalizations is an important part of a birder's toolkit. Sound information can assist in the locating, watching, identification, and sometimes sexing of birds. Recent developments in audio technology have seen
recording and reproduction devices shrink in both size and price, making them accessible to a greater portion of the birding community. The non-linear nature of digital audio technology has also made selecting and accessing the required recordings much more flexible than tape-based models. It is now possible to take a recording of every bird call you are likely to encounter in a given area out into the field stored on a device that will slip into your pocket and to retrieve calls for playback and comparison in any order you choose. As the technology continues to improve, researchers and hobby birders have started using convolutional neural networks to mine sound recordings to identify and track specific bird calls.
Photography Photography has always been a part of birding, but in the past the cost of cameras with
super-telephoto lenses made this a minority, often semi-professional, interest. The advent of affordable
digital cameras, which can be used in conjunction with a spotting scope or binoculars (using the technique of
afocal photography, referred to by the
neologism "
digiscoping" or sometimes
digibinning for binoculars), have made this a much more widespread aspect of the hobby.
Videography As with the arrival of affordable
digital cameras, the development of more compact and affordable
digital video cameras has made them more attractive and accessible to the birding community. Cross-over, non-linear digital models now exist that take high-quality stills at acceptable resolutions, as well as being able to record and play audio and video. The ability to capture and reproduce not only the visual characteristics of a bird, but also its patterns of movement and its sound, has wide applications for birders in the field.
Portable media players This class of product includes devices that can play (and in some cases record) a range of digital media, typically video, audio and still image files. Many modern
digital cameras,
mobile phones, and
camcorders can be classified as
portable media players. With the ability to store and play large quantities of information, pocket-sized devices allow a full birding multimedia library to be taken into the field and mobile Internet access makes obtaining and transmitting information possible in near real time.
Remote birdwatching New technologies are allowing birdwatching activities to take place over the Internet, using robotic camera installations and mobile phones set up in remote wildlife areas. Projects such as CONE 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.
Communication In the early 1950s, the only way of communicating new bird sightings was through the postal system and it was generally too late for the recipients to act on the information. In 1953 James Ferguson-Lees began broadcasting rare bird news on the radio in Eric Simms'
Countryside program but this did not catch on. In the 1960s people began using the telephone and some people became hubs for communication. In the 1970s some cafés, such as that in
Cley, Norfolk run by Nancy Gull, became centers for meeting and communication. This was replaced by telephone hotline services such as "Birdline" and "Bird Information Service". 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
social 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), probably has the most subscribers, followed by the English-language fork of
Eurobirdnet, Birding-Aus from Australia, SABirdnet from South Africa and Orientalbirding.
Mobile applications The increasing availability of mobile devices in the 2010s allowed the smartphone to become a useful tool for birding. Mobile apps can be used as replacements for physical birding field guides, such as the digital version of the
Sibley Guide to Birds and the official Audubon Society app. Other apps utilize
machine learning to automatically identify birds from photographs and audio recordings, such as the Cornell Lab of Ornithology's
Merlin Bird ID application and
iNaturalist.
Cornell Lab of Ornithology's
eBird database is a popular tool used by birders to document their sightings. In addition to serving as a
citizen science project used by ornithologists to document trends in bird populations, it allows birders see recent reports by other birders and search by species and location. Some species, including endangered species and others likely to be disrupted by increased human activity, are designated "sensitive species" by eBird and have locations of sightings hidden from the general public.
Code of conduct As the numbers of birdwatchers increases, there is growing concern about the impact of birdwatching on the birds and their habitat. Birdwatching etiquette is evolving in response to this concern. Some examples of birdwatching etiquette include promoting the welfare of birds and their environment, limiting use of photography,
pishing and playback devices to mitigate stress caused to birds, maintaining a distance away from nests and nesting colonies, and respecting private property. The lack of definite evidence, except arguably in the form of photographs, makes birding records difficult to prove but birdwatchers strive to build trust in their identification. One of the few major disputes was the case of the
Hastings Rarities. ==Socio-psychology==
