Adjacent to/nearby KATMAI. (Adapted from author's abstract.) Bald eagle nesting success was examined from Cape Kubugakli to American Bay during the summer of 1990. A total of 245 nests was recorded, with productivity monitored on 117 nests. The mean clutch size was 1.89 eggs, with 35 nests containing 3 eggs. Hatching success was low at 44%, while brood rearing success was 82%, with pair productivity at 0.35 fledglings/egg laid. Nesting success (55%) and nest productivity (0.81-0.90 fledglings/occupied and/or active nest) closely paralleled that recorded in 1989. Habitat use also paralleled 1989 results, with nearshore islands/islets used more frequently for nests than other available habitat types. Fifty-four percent of the 1989 nest sites were reused in 1990.
