N2 - In this pilot study, we compared visually estimated seabird numbers collected during an aerial transect survey with numbers derived from digital aerial photographs of the same transects. The results of this study suggest that the observational survey significantly underestimated the number of sea ducks. The difference between visual and photographic methods varied considerably among species.
