A diverse range of bird species can be found in Balcombe. From small woodland birds to birds of prey, we want to develop an understanding of which bird species are present, where, and when. Therefore, the Balcombe Ecological Society undertakes a mixture of ornithological (bird) surveys.

Breeding Bird Surveys

Breeding Bird Surveys, often abbreviated to BBS, are one of the most common bird surveys carried out. These surveys monitor population changes among widespread breeding birds. Carried out between March and June during the peak spring and early summer breeding season, these surveys provide valuable scientific data. One visit is carried out per month to establish accurate and representative data. Surveys begin around 30 minutes after dawn to align with peak morning activity. Our survey routes span across the Parish.

Winter Bird Surveys

Winter Bird Surveys, referred to as WBS, are surveys undertaken from November to February, outside of the breeding season. The Society conducts structured WBS across the parish. These surveys are essential for assessing habitat carrying capacity and winter foraging corridors. One visit is carried out per month, and surveyors walk a predetermined transect route within a defined Red Line Boundary (RLB).

Data verification and conservation impact

Every ornithological survey conducted by the Balcombe Ecological Society follows a verification process:
– Field records are logged with Ordnance Survey grid references, count totals, and BTO status codes into the Balcombe Parish Biological Database.
– Data is submitted directly to the BTO via BirdTrack, the Sussex Ornithological Society, and the Sussex Biodiversity Record Centre to inform regional conservation strategies and local planning consultations.
Please note that locations for Schedule 1 species and sensitive breeders are generalised.
