We estimated the adult tern population on July 16, 1945, to be 5000. It has been much more in some seasons.  ...  The number of gulls there, and hence the density of population, is not much different from that at Large Weepecket from 1942 to 1944. However, Penikese is seven times as large as Weepecket.  ...
