Movements of walruses radio-tagged in Bristol Bay, Alaska / Chadwick V. Jay, Sue Hills.

Title: Movements of walruses radio-tagged in Bristol Bay, Alaska / Chadwick V. Jay, Sue Hills.
Author(s): Jay, Chadwick V.
Hills, Sue.
Date: 2005.
In: Arctic. (2005.), Vol. 58(2) (2005)
Abstract: Satellite radio-location data from 57 adult male Pacific walruses (Odobenus rosmarus divergens) were used to estimate haul-out fidelity, describe seasonal foraging distributions, and determine timing of autumn migration from Bristol Bay, Alaska. Data were collected May to October 1987-91 and 1995-2000. Mean fidelity was 0.56 (SE = 0.09). Small sample sizes precluded comparisons of fidelity among years and among haul-outs by season. No tagged animals migrated out of bay between spring and early autumn. Combined monthly locations suggest foraging occurs primarily in southern and eastern bay areas in spring and shifts northwestly in late autumn and winter. Ninety-eight percent of the in-water locations were in waters under 60 m deep, which account for 76% of the study area. Some animals migrated out of bay in late autumn and winter; long-range migrants departed November and December; others remained within the bay throughout year.
