Birdwatching, twitching, birding, or amateur ornithology can be a casual and unexpected enjoyment, as well as an ambitious pursuit to see the most unusual species.
The early bird is a well-known idiom. Birds are usually most active at sunrise.
Minimize sound and motions, to avoid disturbing the birds. Most birds see better than people do, and probably see you before you see them.
Many bird sanctuaries are in difficult terrain; wetlands, rocks or shorelines. Be sure to find safe ground, or a safe vessel.
Birds might be aggressive against intruders; see dangerous animals. Nearly all living animals have parasites on them; see pests.
Bird flu, or more formally avian influenza, can infect both birds and mammals. Fewer than a thousand cases have ever been reported in humans, but some of them have been fatal. Most have involved people who work with poultry, but there is also some risk to birdwatchers. The main transmission methods are by contact with dead birds or the wastes of live ones; avoid those and you should be safe. For more information, see the World Health Organization page on the topic.
Birdwatchers can attract birds by handing out feed. This is controversial, as birds can get malnourished (especially their chicks), migratory birds can be lured to stay for too long, and the feed can attracts rats and other pests. In cities birds used to being fed can be intimidating. Cities and national parks might prohibit feeding. Feeding is common practice at some locations, but doing it right is fundamental to avoid problems. Prefer feed that is part of the birds' natural diet, instead of processed food, such as bread. This is critical for young birds; those that mostly eat bread might become dangerously malnourished. If possible, use a feeding table that hinders the birds' excrements from getting into the food and keeps land animals away. If you put the feed on the ground, get it out in the morning or at least well before sunset, so that the feed is consumed by the birds before darkness. In regions with birds migrating away in autumn, do not feed them when they should leave.
Winter feeding helps sedentary birds to survive until spring. However, it soon makes them dependent on the feeder; winter feeding is a commitment which you should maintain throughout the season, or avoid from the beginning.
You can always observe and listen to the birds that live in your home town or wherever you are visiting. Many birds live in urban and semi-urban environments, including some that sing exquisite songs, such as the Eurasian blackbird, which has a wide range that includes the largest cities in Northern Europe and sings for several months of spring and summer, during its mating season. American robins also sing very pretty and varied songs, though not to the degree that Eurasian blackbirds do, and they are common in many US cities including New York City, particularly in parks. Even protected species are not always hard to spot; for example, if you are visiting the coast of California, you are likely to see pelicans and other large sea birds that are not at all reticent to be around people.
Birds such as pigeons and sparrows might prefer cities; however, many people regard them as pests, rather than living attractions.
Migratory birds can often be seen in great numbers where they wait for good weather to cross large bodies of water, or wait out a prolonged winter at higher latitudes. Capes stretching out into the water and wetlands in the vicinity are often good places to look for migrating birds. These places are usually well-known by local birders and not hard to find information on. Sometimes there is infrastructure, such as birdwatching towers.
Quite often, merely a trip to a decent-sized urban park with a lot of foliage is sufficient to observe many migratory birds in season. However, for advanced birders, some of the bird sanctuaries and habitats below can be a special experience.

The exotic fauna of Australia includes birds that visitors from the rest of the world may not have seen. Even in central Sydney, you may see and hear white ibises (colloquially called as bin chickens), sulphur-crested cockatoos and laughing kookaburras.
Native birds, some of which are neither exotic or flamboyant but nevertheless interesting, are watchable from a range of locations in Australia known as "Bird Observatories." What was originally the Royal Australian Ornithological Union, but is now called Birdlife Australia, has observatories at:

The leave-no-trace principle is important for birdwatching.
Travellers can be tempted to gather remnants such as egg shells or feathers; however, this behaviour may unintentionally disturb birds and in many countries it is illegal to do so. Also, bird flu can be transmitted by contact with dead birds or the waste of live ones; the risk is small in most areas, but best avoided.
The use of pre-recorded audio lures, mimicked bird calls or a "pish-pish-pish" noise (colloquially known as "pishing") in birdwatching is as controversial a topic as any. The safety and well-being of any bird being pished should always be considered, and once the bird has appeared in view all pishing activity should cease. If you are in a group, it is advisable to ask before pishing a bird as some birders disagree with the practice.
Traditionally, pishing is done by a person simply keeping still and making a soft "pish-pish-pish" noise hoping to attract any curious birds nearby. Small birds can be attracted in this manner. Another pishing technique involves mimicking a specific bird's call, such as the distinctive "HOO-hoo" call of a cuckoo or drumming on a tree to imitate a woodpecker. Modern technology, however, has introduced the use of pre-recorded audio lures that anyone with a smartphone can access. This has led to an increase in people engaging in pishing, some of whom do not understand the possible repercussions such as causing birds to waste energy in seeking a perceived intruder. Pre-recorded audio lures should be used sparingly in all instances.
Pishing near nests or during the breeding season should only be undertaken for scientific purposes and not for "getting a better look or better photograph". Disturbing breeding birds is often illegal and in any case against the general ethics of birdwatching.
