This study deals with the influence of benthos abundance when
assessing the potential impact of a small wind park on wintering sea
ducks. Using the Before-After-Control-Impact design, it was suggested
in a recent study (Guillemette et al. 1998) that the wind park provoked
a decline in the abundance and a change in the distribution of common
eiders Somateria mollissima and common scoters Melanitta nigra .
However, the observed decline in sea duck abundance occurred concomitantly
with a decline of benthic food supplies. We measured concomitant
