Using a Drone Around Wildlife: Impacts, Rules and Responsible Flying

What the research and regulators say about drones and wildlife, and a practical code for flying without causing disturbance.

By the Expedition Wildlife editors · · Global

Drones have changed how we see landscapes and, increasingly, wildlife. Researchers use them to count seabird colonies and survey whales; filmmakers use them for aerial views that once needed a helicopter. But a drone is also a loud, fast-moving object in the sky — which, to many animals, looks a lot like a predator.

This guide covers how drones can disturb wildlife, the main rules in the United States and Europe, and a practical code for flying responsibly. Rules change and vary by location, so treat the regulatory sections as a starting point and confirm them with the authority for the place you will fly.

How drones disturb wildlife

Disturbance is not always obvious. Some animals flee, dive, flush from nests or stampede. Others freeze or carry on apparently unbothered, while their stress response rises. Repeated disturbance costs energy, interrupts feeding, and can leave eggs or young exposed to cold, heat or predators.

The risk is highest when:

  • Animals are breeding. Seabird colonies, heronries and raptor nests are especially sensitive; adults flushing from a nest even briefly can lose eggs or chicks to gulls or the weather.
  • The drone approaches directly or descends from overhead. Experimental work with birds found that the angle of approach matters, with vertical approaches more likely to provoke a reaction than gradual horizontal ones.
  • Animals are in groups. A flushed flock or herd can trample young or scatter.
  • Raptors are nearby. Eagles, hawks and falcons sometimes attack drones, risking injury to the bird.
  • Flights are repeated. One pass may be tolerated; many passes by many visitors are not.

Where you can and can't fly

United States

  • FAA rules apply everywhere in US airspace. Recreational flyers follow the recreational flyer rules (TRUST, registration if applicable, Remote ID, visual line of sight, altitude limits, airspace authorizations). Anyone flying for business or paid work needs a Part 107 remote pilot certificate.
  • National parks: flying is prohibited in most park units unless a superintendent has specifically authorized it. This includes launching from or landing on park land and water.
  • Wildlife refuges, wilderness areas and state lands have their own restrictions; many prohibit drones or require a permit. Check the managing agency (USFWS, US Forest Service, BLM, or the state) before you go.
  • Marine mammals and sea turtles are protected under federal law. Flying in a way that disturbs them can amount to harassment, and specific approach rules apply in some areas.

UK and European Union

  • In the UK, the Civil Aviation Authority's Drone and Model Aircraft Code sets the basics, including registration (Operator ID and Flyer ID for most drones) and a 120-meter (about 400-foot) maximum height.
  • In the EU, rules are set under the EASA framework, with most hobby flying in the "Open" category and national authorities handling registration and local restrictions.
  • Nature reserves, national parks and protected areas in both regions frequently restrict or ban drones, and disturbing protected species can be a criminal offence.

A practical code for flying near wildlife

  1. Know the rules for the exact place. Airspace, land manager rules and wildlife law all apply at once.
  2. Don't fly over breeding sites. Avoid nests, colonies, dens and calving areas entirely during the breeding season.
  3. Launch far away and approach slowly. Take off well out of sight and earshot of the animals, climb, then approach gradually and horizontally rather than diving in from above.
  4. Keep your distance and altitude. Use your zoom, not proximity. If animals look up, move, call, bunch together or change behavior, you are too close — back off immediately.
  5. Keep flights short. Get the shot and leave. Do not follow or herd animals.
  6. Watch for raptors. If a bird of prey approaches, climb and fly away or land.
  7. Do not share precise locations of sensitive sites such as nests in captions or metadata.
