Hamer TE and Nelson SK. 1995. Nesting chronology of the Marbled Murrelet. Pages 49-56. In Ralph CJ, Hunt GL, Raphael MG, Piatt JF. Ecology and conservation of the marbled murrelet. Pacific Southwest Research Station, Forest Service, U.S. Department of Agriculture. Albany, CA
Based on 86 breeding records, the authors document a long breeding period for Marbled Murrelets (182 days). Breeding records were obtained from: California, including one at Prairie Creek Redwoods State Park (in Redwood National and State Parks), Oregon, Washington, British Columbia, and Alaska. In researching nesting ecology, the authors looked for information on 'timing and lengths of breeding activities and what factors affect this timing.' With such data, activities in breeding areas can then be timed for least disturbance, and surveys of nests and of birds at sea can be more effective. Methods and results are described. Table 1 lists all the individual observations of nests/young, and a second table shows number fledged by time intervals. Figures: two graphs of fledging dates and number of young fledged, summary of breeding phenology for 4 states and British Columbia.
