Field Notes Doug Bell June 24, 1989 [illegible] [illegible] Counted 17 Oystercatchers on W Beach area & reefs, with 2 nests (1 chick + 3 eggs) on the beach. I set up my blind in the W beach [consists largely of heavy pebbles], and marked a weighed eggs ahead of checking morphotypes because so many nests are hatching today! What a hot day, sunny, little wind until evening. June 25, 1989 Foggy, misty morning. Went to blind at 11:30 to start checking morphotypes. Remained in blind until 17:00. Got data on 35 1/2 pairs. When I left the blind 2 older gull chicks ran from a nest near my tent. One of them even went into the surf. By the time I climbed to the top of the bluff and looked back at the beach, one chick was being killed by another gull. While back at camp from 19:10 - 19:30 the sub-ad. Bald Eagle showed up and decisively coursed around the SW end of Dextinction I with a contingent of screaming gulls & crows in tow. Went back to the blind with my parabolic & recorder. Took a chick (newly hatched) from pair 20 + placed it in the nest (36) where the chicks had run away. The adult gulls were quite upset. The male came up to the nest and picked at the chick's head, so did the female. The chick was letting out desperation calls. The pair 36 [both S/C] long called a number of times, then walked off from the nest. But then the F walked back over to the nest and sat on the chick.
