Undertaking a Nesting Bird Survey for Development

All wild birds, including nesting birds, breeding birds and wintering birds are a protected species under the Wildlife and Countryside Act 1981 as amended. Section 41 of the Natural Environment and Rural Communities (NERC) Act 2006 also provides protection for birds by placing a duty on public authorities to conserve biodiversity.

This protection means that it is illegal to intentionally kill, injure or harm any bird species or to destroy or damage active bird nests. It is for this reason that nesting bird surveys and mitigation plans must be put in place for development projects if nesting birds may be present on or near the development site.

Types of Bird Survey

There are many different types of bird surveys, including:

  • Nesting bird survey
  • Breeding bird survey
  • Wintering bird survey
  • Barn owl survey
  • Rare bird survey
  • Wetland bird survey
  • Common bird census

When to Carry Out a Nesting Bird Survey

Like many types of ecology survey, there are seasonal constrains which limit when a nesting bird survey can take place. A nesting bird survey should be carried out during nesting season, which is from March to August.

Nesting bird checks must be undertaken prior to any vegetation being removed from a development site within the breeding bird season (March – August inclusive). The nesting bird check should be undertaken no more than 24 – 48 hours prior to the vegetation removal by a suitably experienced ecologist.

Nesting Bird Survey Methodology

During this type of survey, the site is visited by a qualified ecologist who will carry out a thorough inspection of all buildings and trees on the site looking for specific evidence that points to use of the site by nesting birds. Evidence of nesting birds can include, feathers, droppings, nesting materials, as well as active bird activity.

What Happens if Nesting Birds are Found During a Survey?

If nesting birds are found to be present on the site, and the development taking place on the site could have any impact on the bird population, mitigation measures should be put in place.

If any nests, or nests in construction are located, a suitable stand off should be maintained until the young have fledged.
