Wintering birds

Bird surveys can be conducted on a wide range of suitable habitat depending on survey objectives and or development type

Surveys typically involve a modified version of the BTO/JNCC Breeding Bird Survey (BBS) (or the Brown & Shepherd technique on uplands) to record the number and species of all adult birds on the survey site. The site is visited on a minimum of three occasions, between mid-March and mid-July.


During each survey visit a predetermined transect is walked at slow pace and all birds encountered are recorded on suitable scaled field maps the standard BTO codes. Details such as sex, age (juvenile or adult) and behaviour are also recorded. Any nests located during the course of the survey are marked on the map; as are the weather conditions, time, date and duration.

Other bird surveys such as winter wader counts and vantage point watches can also be completed, using the standard methodology recommended by Scottish Natural Heritage to inform impact assessment of onshore wind farms.
