This is the species data layer showing seasonal naive species occurrence. ?Naive? means that these species counts should not be taken as a direct index of relative abundance, since absence of detections does not imply the species does not occur there. Counts (detections) were adjusted using the five-minute equivalent effort units; however due to biases in methods, these maps combining multiple surveys should be used as ?presence? maps that strongly reflect survey effort. The data encompass all years but is split out by season for each species; only one species and one season are shown at a time. This layer displays occurrence for Northern Gannet, Greater Shearwater, Long-tailed Duck, and Dovekie for the winter, spring, summer, and fall seasons.
