资源简介：
This data set contains flock IDs and flock size (number of individual birds) and flock locations of spectacled eider flocks encountered during the late winter aerial surveys from 1995 to 2020. Flock size is based on either counts from digital photos, or visual estimates made by observers for flocks that were not photographed.
