Field Notes Doug Bell June 15, 1989 now high enough to support a tern colony (I don't recall a large tern colony here last year). Probably fewer than 700 Caspian Terns in the colony. These birds are also less "nervous" than the colony over on Sand Island. Spent the day from 10:00 - 19:15 in blind, then measured and weighed eggs from 19:15 - 21:15. 3/4 moon out, broken clouds, beautiful night sky. Surprisingly, the entire colony became quiet after 22:00. June 16, 1989 The Caspian Tern colony became noisy at 04:30. But I slept until 06:00. Went right to study site at the high dune area, finished weighing some eggs, then climbed in the blind. Got all morpho-types on my pairs by 08:45. Then got out the gun to collect a couple birds. Thought I would try to get a particular W&W pair with one shot. The angle from the blind was good to possibly even pick up a third bird. While I was planning this out the pairs began mutual preening and all congregated in line as I fired. 4 dead gulls resulted! As I packed them up I noticed a fifth dead bird further back. So, all for me shot - 2 mated pairs (DAB 495, 496, 497, 498) and one single (499). Turns out, the single belonged to a 3 chick nest whose mate showed up. So I shot him (DAB 500), then put the chicks in other
