E.M.Brock 1957 Journal Barrow, Northern Alaska July 29 and looking north, I could notice large flocks (100-300) of ducks flying in a westerly direction. There seemed to be a continuous stream of them, one groups following another - always at least one group in sight. Upon returning to the lab, I told Dr Miller (S.F. Academy) about the ducks (he is trying to establish whether radar has any effect on ducks in flight). He mentioned that he had already seen a few. Dr Miller and I went to the airport where Dr. Miller has a small radar screen which he is permitted to point [illegible] in a desired direction. We were at the location for about three hours during which we observed at least 25 groups of ducks varying from 100 to approximately 400 ducks per group, all flying around the point (where the Koreans would shoot at them) and west. Although there had been reports of large groups coming by previous days today, Dr. Miller stated that today's amount probably exceeded previous days.
