PROTECTED SPECIES SURVEYS Wintering Bird Surveys
Expert Ornithological Assessments for Planning & Conservation
What Are Wintering Bird Surveys?
Wintering bird surveys are essential ecological assessments undertaken between November and February to identify and monitor bird species that overwinter in the UK. These surveys provide crucial data on species presence, abundance, and habitat usage during the non-breeding season — a vital consideration for planning applications, particularly near designated sites or sensitive habitats.
Why Are They Important?
Wintering birds, including wildfowl, waders, and other migratory species, are protected under UK legislation and international conventions. Development that affects their habitat, feeding grounds, or flight paths can have significant ecological impacts. Conducting robust wintering bird surveys:
Ensures compliance with planning policy and biodiversity regulations
Supports Habitat Regulations Assessments (HRA)
Informs Ecological Impact Assessments (EcIA)
Helps identify the need for mitigation or compensation measures
When Are Wintering Bird Surveys Required?
Wintering bird surveys may be required if your site is:
Close to or within a designated site (SPA, Ramsar, SSSI)
Adjacent to wetlands, estuaries, or coastal habitats
Known to support significant numbers of overwintering bird species
Part of a large-scale development with the potential to disturb roosting or feeding grounds
Early engagement with a qualified ecologist can help determine if your site needs wintering bird surveys as part of the planning process.
WITHERING BIRD SURVEY Survey Methodology
Our wintering bird surveys follow industry best practice and are undertaken by experienced ornithologists in accordance with guidance from Natural England and the Chartered Institute of Ecology and Environmental Management (CIEEM). Surveys typically include:
Monthly counts (November to February)
Vantage point surveys for flight lines and disturbance
Transect and point count methods to record presence and behaviour
Detailed mapping and habitat assessments
Data is analysed to determine species importance and site usage across the winter period.
Our Expertise
We offer high-quality wintering bird surveys across England, with particular experience in:
Coastal and estuarine environments
Wetland and floodplain habitats
Agricultural landscapes and brownfield sites
Sites near Special Protection Areas (SPAs) and Ramsar sites
Our team has an in-depth understanding of the legal and planning frameworks that govern avian ecology and can provide clear, practical advice to support your application.
