Bird Surveys

Our experienced ecologists can undertake a variety of bird survey work, either as part of a planning application or prior to site work.

Nesting bird surveys are undertaken where work is proposed that could disturb nesting birds and result in a breach of legislation (such as vegetation removal or demolition within the nesting bird season). Breeding bird surveys tend to be done to establish the value of the site for birds, as part of a planning application.

Bird Legislation

All wild birds in the UK are protected under Section 1 of the Wildlife and Countryside Act 1981 (as amended) which makes it an offence to intentionally kill, injure or take any wild bird or to take, damage or destroy the nest (whilst being built or in use) or its eggs.

Bird species, such as barn owl, are listed in Schedule 1 of the Wildlife and Countryside Act 1981 and receive further protection which makes it an offence to intentionally or recklessly disturb these species while building, on or near a nest containing eggs or young; or to disturb dependent young of such a bird.

Bird Seasonal Constraints

Breeding and nesting bird surveys can only be undertaken during the active bird nesting season, which runs from March through to the end August. Please click below to view our bird survey and mitigation calendar.

Breeding Bird Surveys

Breeding bird surveys are conducted using a methodology based on the British Trust For Ornithology(BTO)/Joint Nature Conservation Committee Breeding Bird Survey (BBS) to record the number and species of all adult birds on the survey site. The site is visited on a minimum of four occasions, three at dawn and one at dusk. On each visit a set transect is walked at slow pace and all birds encountered on the transect are identified by sight or by sound and marked on a location map using the standard BTO codes. In addition, all nests located during the survey are marked on the map.

Nesting Bird Surveys

Nesting bird surveys are generally required immediately prior to work commencing on site to ensure that there are no nesting birds or active nests within the area of work.

Barn Owl Surveys

We have considerable experience of undertaking barn owl surveys, on both smaller and larger sites. Surveys for barn owls can generally be carried out at any time of year. Barn owl surveys involve the internal and external inspection for likely entry / exit points and field signs, such as feathers, droppings, casts and nest debris and eggs. The results are then used to make an assessment to establish numbers and the level of use by barn owls.
