  2. Surveying marbled murrelets at inland forested sites: a guide

    The marbled murrelet (Brachyramphus marmoratus), a seabird, nests in forested stands from southeast Alaska south to Santa Cruz, California. Because of this species' close association with old-growth forests, researchers and land managers need a method to assess murrelet distribution and use patterns throughout its range. This guide describes a...

  3. Breeding distribution of the marbled murrelet in Redwood National Park and vicinity during 1988

    We report on an intensive research effort to determine the present status of the marbled murrelet (Brachyramphus marmoratus) in the vicinity of Redwood National Park, in Del Norte and northern Humboldt Counties, California. This seabird is primarily an inhabitant of the nearshore waters and adjacent coastal redwood forests of the northern half of the...

  4. Stand-scale habitat associations across a large geographic region of an old-growth specialist, the marbled murrelet

    We used two metrics, occupancy and relative abundance, to study forest stand characteristics believed to be important to a threatened seabird that nests in old-growth forests, the Marbled Murrelet (Brachyramphus marmoratus). Occupancy refers to murrelet presence or absence based on observed bird behaviors, while relative abundance refers to...

  5. Logistic regression accuracy across different spatial and temporal scales for a wide-ranging species, the marbled murrelet

    The scale at which habitat variables are measured affects the accuracy of resource selection functions in predicting animal use of sites. We used logistic regression models for a wide-ranging species, the marbled murrelet, (Brachyramphus marmoratus) in a large region in California to address how much changing the spatial or temporal scale of...
