Bird watching: dos, don'ts and citizen science

A few simple rules make the difference between a good experience and a damaging one — for the birds and for everyone else.

Birdwatching is one of the most accessible wildlife activities in the world. You need very little equipment, no special access, and no particular expertise to get started. But like any activity that takes you into close proximity with wild animals, it comes with responsibilities.

The Dos

Move slowly and quietly. Birds are acutely sensitive to sudden movement and noise. Walk at a measured pace, avoid crunching through undergrowth when you can help it, and speak in low voices if you're with others. You will see far more by moving like you belong in the landscape than by crashing through it.

Use binoculars, so you don't need to get physically close to a bird to observe it well. A bird watched from twenty metres through good optics, going about its natural behaviour, is a better experience than the same bird flushed from five metres because you pressed in too far.

Learn to read disturbance signals. A bird that raises its head and stops feeding, one that begins calling repeatedly, one that crouches low or stretches tall — these are signs of stress. When you see them, the correct response is to increase your distance, not hold your ground. If a bird flushes, let it go. Don't follow it.

Stay on paths at seabird colonies. Cliff-top turf at puffin and gannet colonies is riddled with burrows, making the ground both fragile and unstable. Marked paths exist for the birds' protection as well as your safety.

Give nesting birds space. If you find a nest — particularly a ground nest, which is easy to stumble across in summer — back away quietly and leave it alone. Note the location by all means, but don't return repeatedly to check on it, and don't share the exact location publicly in a way that draws other visitors.

Be patient. The single most effective birdwatching technique is to find a good spot and stay still. Birds that have been disturbed by your arrival will often return and resume normal behaviour within minutes if you stop moving. Patience consistently outperforms pursuit.

The Don'ts

Don't use drones. This has unfortunately become increasingly common, and the damage it causes is serious. A drone flying near a seabird colony triggers mass panic — birds flush from nests en masse, eggs and chicks are exposed to predators and weather, and the disruption can last long after the drone is gone. Studies of drone disturbance at colonies have recorded nest abandonment rates that, at sensitive sites, represent a meaningful conservation impact. In the UK, flying a drone near a Schedule 1 species at its nest is a criminal offence. At any seabird colony, it is simply not acceptable, regardless of legality. The photograph is not worth it.

Don't use playback at breeding sites. Broadcasting recorded birdsong through a phone or speaker to attract a bird into view is a practice that divides the birdwatching community, but the case against it at breeding sites is clear. A territory-holding bird that hears a rival call responds with stress — elevated heart rate, time and energy diverted from feeding and brooding to threat display. At popular sites with many visitors, the cumulative effect of multiple people playing the same call is genuinely harmful. The RSPB and BTO both advise against playback at or near nests. If you wouldn't do it in a nature reserve, don't do it in the field.

Don't approach active nests. In the UK, most wild bird nests, eggs, and chicks are protected under the Wildlife and Countryside Act 1981, and disturbing an active nest is a criminal offence. Beyond legality, the reasoning is simple: disturbance causes abandonment and increases predation risk. If you come across a nest, leave it immediately and don't go back.

Don't feed birds in ways that create dependency or attract predators. Supplementary feeding through bird feeders is currently under debate - whether it is beneficial, or if they have become a breeding ground for diseases. Feeding at wild sites — particularly at seabird colonies or nature reserves — can attract rats and other predators, disrupt natural foraging behaviour, and cause birds to associate humans with food in ways that create problems for them long after.

Don't share precise nest locations on social media. A geo-tagged post of a rare breeding bird will attract other visitors, some of whom will not exercise caution. Rarity draws crowds, and crowds cause disturbance regardless of good intentions.

Don't pursue a bird that is trying to get somewhere. A puffin carrying fish back to its burrow, a tern making a feeding run — these are animals mid-task. Getting in their way, however briefly, has a cost. Step aside, watch from where you are, and let them do what they came to do.

Don't underestimate the cumulative effect of group behaviour. A single visitor approaching a colony too closely causes minimal damage. Fifty visitors each doing the same thing across a busy summer morning causes a great deal. Be conscious of your individual behaviour even when — especially when — everyone around you seems to be doing the same thing.

Adding Citizen Science to Your Birdwatching

Digital platforms — primarily eBird, run by the Cornell Lab of Ornithology, and BirdTrack in the UK — turned individual sightings into collective datasets of extraordinary scale. eBird alone now receives over 100 million observations per year from observers in virtually every country on Earth. When scientists need to understand how a species' range is shifting in response to climate change, or whether a population decline flagged at one colony is being replicated elsewhere, they increasingly turn to this accumulated record of what ordinary people saw, where, and when.

This is not a small thing. Professional monitoring programmes are expensive and geographically limited. Citizen science fills the gaps — in space, in time, and at a scale no institutional budget could match.

Getting started is simple. Download eBird or BirdTrack, create a free account, and start a checklist when you begin a walk. Log every species you see, with a rough count, and submit when you're done. The apps work offline and sync when you have signal. You don't need to be an expert: even a list of the common species at a well-known site is useful, because it tells researchers something about what was there, when, and in what numbers.

Photographs, when you have them, are worth attaching. They provide verification for unusual records and, for difficult-to-identify species, are often what allows a record to be accepted rather than queried. A phone photo showing the key field marks is sufficient for most purposes.
