Abstract
Aerial and boat-based surveys for Marbled Murrelets (Brachyramphus marmoratus) were conducted simultaneously over short transect distances (ca. 2 km) in three different areas of the Alexander Archipelago to assess the accuracy and variability of aerial counts compared to boat-based counts. Additional aerial surveys were conducted over a wider geographic area to assess temporal and spatial variability of murrelet aggregations.
