1944 June 23 Biel Arwey Journal - most follows and its flock is reforming out there. My impression is that the flock is nowhere as large as when first noticed. The flock itself has no particular shape to it, and is definitely not strung out in a front moving in one direction. 9:50 flock is moving back in its direction from which it came. 9:55 - a very active flock is spotted 1/2 SE of East landing. as I watch I can see probably over 1000 birds, mostly from West end colonies, moving out to it. It has a moderate number of very active birds now and is moving due W. much movement within the flock, and probably [illegible] over 100 arriving per minute. Can watch long streams moving down the W side of the island & past seal rock. Birds can be seen headed out to them from both sides of the Island. 10:10 - flock is very active now. Can almost be visibly seen moving en masse to the west can be seen with the naked eye. The front is moving very fast. Shape: E -> W wind There are thousands of birds in this flock and it is extremely dense. Seems to be general one way entrance and exit. Birds are leaving from the W side, Enters from the E side some after traveling the whole length of the flock.
