Annotated version to assist counting
观察细节
At the time I estimated this flock to be at least 200. From the photo I count 788 birds. At the time I estimated 10 of the group to be BRBL or blackbird sp, it was almost all EUSTs. So increasing my estimate of the blackbird portion roughly like the increase in estimated versus actual number of starlings leads me to believe about 40 of the birds in the photo might've been blackbirds. (788/200 = x/10 so x=39.4? don't know how reasonable this is). So I'm truncating 788 to 750 starlings.
