Abstract:
Seabirds transect surveys were conducted in Baltic Sea from 1992 to 1999. Standard seabird offshore sampling techniques assume that line transect of 300 m width is basically used for counting birds sitting on the water surface, whereas the 'snap-shot' method is used for the counting of flying birds at strongly fixed intervals of time.<br><br>
Additional efforts were put into studies of the offshore seabird and waterfowl movements. We recorded flying
birds along 1,000 m wide transect over the 'classic' 300 m transect used for calculations of seabird densities
during 'snap-shots'.
