Bird Surveys

Bird Surveys for Planning & Development

Clear, proportionate bird surveys and nesting checks to keep your project compliant, on schedule and planning-ready. 

Do you need an Bird Survey?

If your site contains trees, hedgerows, buildings, scrub, grassland or any vegetation suitable for nesting, your LPA may require a bird survey or nesting check before planning can proceed. 

What is a Bird Survey?

A bird survey assesses nesting, breeding or wintering activity to determine how works may affect birds on or near a site. It provides the evidence planners need to validate applications and prevents delays linked to the nesting season.

Early Signs a Bird Survey is Needed

LPAs frequently request surveys when: 

  • vegetation clearance is planned March–August 
  • trees, scrub, hedgerows or rough grassland are being removed 
  • barns, outbuildings or roof structures may hold nests 
  • PEA flagged breeding or wintering potential 
  • large sites include farmland, brownfield, wetland or coastal zones 
  • a planner has specifically asked for a bird or nesting assessment 

Early confirmation avoids stoppages, redesigns and compliance risk.

What We Deliver

A practical, proportionate, planning-ready service. 

Service Purpose Outcome
Nesting Bird Checks Confirm presence of active nests before clearance. Clearance can proceed safely or be rescheduled.
Breeding Bird Surveys (BBS) Evidence for planning during breeding season. Species data and planning-ready reporting.
Wintering Bird Surveys Required on larger or sensitive sites. Evidence for planning and mitigation design.
Activity Mapping Identify nesting/foraging hotspots. Clear constraints and opportunities for design teams.
Mitigation & Recommendations If active nests or constraints are found. Practical timelines and construction guidance.

How it Works

Scope & Schedule

Share your site details and programme. We confirm whether a nesting check is enough or if full surveys are needed.

Fieldwork

Nesting checks, breeding bird surveys or wintering surveys depending on season and risk.

Reporting

Planning-ready reports with impact assessment, mitigation options and clear timescales.

Timing & Survey Windows

High-potential sites missing these windows often face delays. 

Securing survey capacity early keeps planning timelines predictable. 

Breeding Bird Season

March – August

Nesting Checks

year-round (limited if nests are active)

Wintering bird surveys

October - March

Legal Compliance & Planning risk

All wild birds, nests and eggs are protected under the Wildlife & Countryside Act 1981. 

For certain species, additional protection applies under the Habitats Regulations. 

Missing or incomplete surveys can lead to: 

  • planning refusal or validation delays 
  • stop-work notices during nesting season 
  • enforcement for disturbing active nests 
  • forced vegetation-clearance rescheduling 
  • timeline disruption due to seasonal limits 

Our role: provide clear, compliant evidence aligned to your programme and design intent. 

What You Receive

  • confirmation of active/likely inactive nests 
  • breeding or wintering survey outputs 
  • species/activity mapping 
  • practical clearance timing advice 
  • planning-ready reporting 
  • mitigation routes for designers and contractors 

Evidence for planners. Clear steps for site teams. No unnecessary surveys. 

If we find an active nest we can create a works exclusion zone/buffer so that works can continue elsewhere on site without disturbing that specific nest

Case Note

Construction works were put to a stop on a site in Basingstoke when they came across a fledgling. We were asked to conduct a nesting bird survey which provided our client with the status of the egg and an estimation of when the fledging was due to fly the nest so that the project could recommence.

Invertebrate Survey FAQs

Do I need a bird survey for planning?

You may need one if your project affects vegetation, building fabric or outbuildings that could support nests, or if your PEA indicates nesting/wintering risk. We confirm this quickly from basic site details. 

Yes, if a nesting-bird check confirms there are no active nests in the work area. If a nest is active, that small area pauses until fledging. 

A nest with eggs or dependent young (including adults sitting or feeding). These are legally protected and cannot be disturbed. 

No. Most small and mid-scale schemes only need a nesting check. BBS is used for larger or sensitive sites.

Site time is usually brief. Turnaround depends on access and scale, but reports are kept concise for validation.

Yes. We set practical timings and method notes that align with planning requirements and site logistics. 

Bird use can influence habitat value and enhancements. We flag any BNG implications so design can incorporate them early. 

When are surveys carried out?

Nesting checks: year-round (but essential March–August). 
Breeding Bird Surveys: April–June. 
Wintering bird surveys: October–March. 

Yes, outside the immediate nest buffer. We help sequence tasks so your wider programme keeps moving legally.

It can. Early scoping avoids timetable conflicts and reduces the chance of conditions that push you into the next season.

Clear presence/likely absence findings, maps where relevant, and proportionate recommendations that protect nests while enabling delivery. 

A nesting check confirms whether active nests are present in the work zone. BBS records breeding territories across a wider area to inform planning or BNG. 

Only when active nests are present or site conditions warrant them. Measures are proportionate to risk. 

A red line plan or postcode, brief description of works, target dates, and any PEA or planner notes. We’ll confirm the right route.
