Summary: | To determine winter population size and late winter distribution, we conducted an aerial survey of the Bering Sea wintering area of Spectacled Eiders (*Somateria fischeri*). During the aerial survey, the photographer (Timothy Bowman) took oblique photographs of 85 flocks. A subset of the best quality digital images were used for annotation and counting in digital image annotation software. A total of 169 digital image files were annotated using Computer Vision Annotation Tool (CVAT) software (Sekachev, B. 2019. Computer Vision Annotation Tool: a universal approach to data annotation [Version 1.1.0, 31 August 2020]. [Online.] Available at https://cvat.org/tasks [17 Sept. 2020]). This collection includes those 169 digital images, all in .JPG format and requiring 2.27 GB of storage space. Filenames are as assigned by the dSLR camera. Some images were cropped to remove areas without eiders, these cropped images were saved with the original filename and the added suffix "cropped". |
