An approach was designed to monitor actual flight activity for lesser blackbacked gull in particular, within and in proximity to the air volumes swept by the operational turbines. VP watches are a means of quantifying flight activity of bird species that take place within and in proximity to the rotor swept area of a wind farm, with the principal aim of determining the likely collision risk after turbines have become operational. The series of field observations in June and July 2011 had the following objectives: - Confirm (to the extent possible) the actual rate of lesser black backed gull collisions within an operational wind farm; - Quantify and characterise the flight activity of lesser black backed gulls within the rotor swept area of an operational wind farm; and - Describe any apparent avoidance and near-blade evasive behaviours to provide qualitative information to inform the choice of gull near-blade “micro” avoidance rate (manifest as evasive flight manoeuvres), and extent of macro-avoidance (which will of necessity reduce rotor passage and collision rates), and to inform the EIA. During each watch, the 180 degree arc area in view was scanned until a target species is detected: at which point it is followed until it ceases flying, is lost from view, or reaches a distance of over 2km from the observer.

Collect data on target species (primarily lesser black-backed gull and other large gull species) that will enable estimates to be made of: • The time spent flying over the defined survey area; • The relative use of different parts of the defined survey area; and • The proportion of flying time spent within the upper and lowest possible height limits as determined by the rotor diameter and rotor hub height. 2. Calculate an index of flight activity for other secondary species using the defined survey area.
