EcoVigour delivers professional bird surveys to support planning and ensure compliance with wildlife legislation. Our surveys identify breeding and wintering bird activity to inform appropriate mitigation and timing of works.
All wild birds, their nests, and eggs are protected under UK law, with additional protections for certain species. EcoVigour provides a range of bird surveys to support development and land management projects.
Why are bird surveys required?
Bird surveys are often required where habitats may support breeding or notable bird species. They help to:
- Ensure compliance with the Wildlife and Countryside Act 1981
- Identify breeding bird activity and sensitive species
- Inform timing of works and mitigation measures
- Support planning applications and ecological assessments
Survey methods
Surveys are undertaken in line with CIEEM guidance and BTO (British Trust for Ornithology) methodologies, and may include:
- Breeding bird surveys using standard territory mapping techniques
- Wintering bird surveys to assess overwintering populations
- Walkover surveys to identify nesting habitat and constraints
- Species-specific surveys for protected or priority species where required
Survey methodology and seasonal constraints
- Breeding bird surveys: typically March to August
- Optimal survey period: April to June
- Wintering bird surveys: November to February
Survey timing is critical to ensure accurate identification of bird activity and legal compliance.
Our approach
- Experienced ornithologists delivering robust survey data
- Clear advice on timing constraints and mitigation
- Practical solutions aligned with project programmes
