Seasonal Drone Restrictions in the UK: What to Watch

Bird Nesting Season (March to August)

The UK's bird nesting season broadly runs from March through August, though some species begin earlier and others extend later. Under the Wildlife and Countryside Act 1981, it is an offence to intentionally or recklessly disturb certain birds while they are on or near a nest, or to disturb dependent young.

For drone pilots, this means:

• Avoid known nesting sites — including cliff-nesting seabirds (puffins, guillemots, razorbills), ground-nesting waders (lapwing, curlew, oystercatcher), raptors (peregrine falcons, golden eagles) and herons
• Schedule 1 species have additional protection — it is an offence to disturb them at or near the nest at any time. This includes species such as the golden eagle, red kite, barn owl, kingfisher, and many others
• Signs of disturbance include birds leaving the nest, alarm calls, and dive-bombing. If you observe these behaviours, move away immediately

Many nature reserves and coastal areas impose seasonal drone bans during nesting season. Check with the site manager or landowner before flying.

Seasonal Temporary Restricted Airspace (TRAs)

• Air shows (typically spring and summer) — TRAs and temporary danger areas are established around display areas. The RIAT (Royal International Air Tattoo), Farnborough International Airshow, and numerous smaller shows all trigger airspace restrictions
• Festivals and large outdoor events — major gatherings may request airspace restrictions for security or safety reasons
• Remembrance Sunday (November) — temporary restrictions may apply around cenotaphs and memorial events
• Royal events — coronations, state occasions and Royal residences may have temporary or seasonal restrictions

These are published as NOTAMs. Check the NATS Aeronautical Information Service for current restrictions before every flight.

Wildlife-Sensitive Areas by Season

Spring (March to May)

• Bird nesting begins — avoid coastal cliffs, heathland and farmland near known nesting sites
• Lambing season on farmland — drones can frighten livestock, and farmers may have strong objections
• Seal pupping on some coasts (grey seals can pup as early as March in some areas)

Summer (June to August)

• Peak nesting season — greatest number of species actively breeding
• Heathland fire risk — some areas restrict all outdoor activities including drone flying
• Increased public use of open spaces — more people to consider under CAA proximity rules

Autumn (September to November)

• Deer rutting season — stags can be aggressive, and disturbance can disrupt breeding. Some estates restrict access
• Wildfowl migration — estuaries and wetlands become important feeding grounds for migratory birds
• Grey seal pupping (October to December) — avoid hauling-out sites on beaches and in caves

Winter (December to February)

• Overwintering wildfowl on estuaries and inland waters — these birds are already stressed by cold conditions and disturbance forces them to use energy they cannot afford
• Short daylight hours — plan flights to maximise available light
• Cold weather battery effects — see separate guidance on mountain and cold weather flying

Seasonal Weather Patterns

• Spring: changeable weather, increasing thermals, risk of sudden showers
• Summer: best overall conditions but afternoon thunderstorm risk and heat haze
• Autumn: stronger winds, earlier darkness, fog risk increasing
• Winter: short days, low sun angle (challenging for cameras), cold batteries, fog and frost

Checking for Seasonal Restrictions

• Check NOTAMs for temporary airspace restrictions related to seasonal events
• Contact local nature reserves and national parks about seasonal drone restrictions
• Review bylaws for Sites of Special Scientific Interest (SSSIs), National Nature Reserves (NNRs) and Areas of Outstanding Natural Beauty (AONBs) — some impose seasonal flying bans
• Consider the Wildlife and Countryside Act 1981 implications for the time of year and location
