of between 1 bird every 7-8 months (95% avoidance) and 1 bird
every 3-4 years (99% avoidance). Taking the precautionary
95% avoidance rate prediction, this would result in
approximately 39 collisions over the 25 year lifespan of the
proposed wind energy development. However, the collision
rate of 1 bird every 7-8 months or 1.56 birds per year would
represent 0.03% of the Scottish resident breeding population
(4500 or 2250 pairs, see Table 12.17). Even though this
excludes the (unmodelled) collision risk during the nonbreeding
season this is expected to be very low and will not
contribute significantly to the estimate. Therefore the collision
risk for tufted duck is considered to be well within acceptable
limits and is thus considered to have a negligible effect on the
species at all population levels (neutral).
