1P. Yen, and F. Huettmann2001UAF - Marbled Murrelet Nest Locations in British Columbia, Canada: Digital DatasetatlasBurnaby, British ColumbiaCentre for Wildlife Ecology, Simon Fraser UniversityfalseThis data set, which exists as an ArcView GIS data layer, contains the locations of all known Marbled Murrelet nest locations within British Columbia. The Marbled Murrelet is a seabird that flies up to 75 km inland to nest in mostly old-growth forest type habitats across elevations. The nest is composed of a bowl-shaped depression on moss-covered branches. Due to the cryptic nature of their nesting behaviour, only a few nests have been found in Canada. Most of the nests in this database are located by telemetry techniques. These data show 'presence only, e.g. The absence of a nest for a region does not infer lack of murrelets in that region (non confirmed absence exists).To create a detailed database of all the located Marbled Murrelet nests within British Columbia, Canada. This dataset is further used to help assess a large-scaled GIS Marbled Murrelet distribution model for coastal British Columbia (Yen et al. 2004), as well as for a forthcoming nest habitat analysis (Huettmann et al. In review)..This data sets exists as an ArcView GIS data layer.

This data cannot be distributed or utilized without confirmation and agreement with the contributing parties. Some data has been previously published elsewhere and is available for use.

This dataset represent known Marbled Murrelet nest locations in British Columbia from 1992 until the present. The purpose of this dataset is to contribute to the construction of a Marbled Murrelet abundance and distribution model, and as such, does not include other nest attributes. The intention is to compile a large-scale representation of Marbled Murrelet nests and inland activity in British Columbia, Canada.
The source scale used to digitize location is 1:250 000 km. Some survey locations are located near the shoreline and may appear to be located in water on other scales.
Data not to be used for navigation.

This methodology has been previously published and should be referred to for full account. Only a brief methodology description will be provided here.
Marbled Murrelets are captured at the onset of the breeding season by dipnetting methods. Radios attached to captured birds by subcutaneous anchors to the back. A suitable bird to be radioed is evaluated by the presence of a brood patch and breeding plumage. Nest locations are first located by helicopter flights, followed by researchers refining the location on foot. Finally, it is confirmed by tree climbers.
The original nest finding method is based on searching nests in trees, e.g. via observing birds flying into the forest.Not all nests were accessible to climbers, therefore, fledgling data not always available.Not all nests were assessable by foot, therefore, the location contains some error.Points representing seabird locations were digitized using 1:250 000 basemap.FieldNest locations have been derived from various methods, but the majority is derived from one main method: telemetry. For survey methods, user must refer to the original documents to determine the specific search methodology and for a complete description of the various methodology, and for interpretation of the data.Centre for Wildlife Ecology1998Desolation Sound, British Columbia Marbled Murrelet nests, 1998Burnaby, British ColumbiaSimon Fraser UniversityfalseCentre for Wildlife Ecology1999Desolation Sound, British Columbia Marbled Murrelet Nests, 1999Burnaby, British ColumbiaSimon Fraser UniversityfalseCentre for Wildlife Ecology2000Desolation Sound, British Columbia Marbled Murrelet Nests, 2000 secondBurnaby, British ColumbiaSimon Fraser UniversityfalseCentre for Wildlife Ecology2001Desolation Sound, British Columbia Marbled Murrelet Nests, 2001Burnaby, British ColumbiaSimon Fraser UniversityfalseCentre for Wildlife Ecology2000Clayoquot Sound, British Columbia Marbled Murrelet Nests, 2000Burnaby, British ColumbiaSimon Fraser UniversityfalseCentre for Wildlife Ecology1998Clayoquot Sound, British Columbia Marbled Murrelet nestsBurnaby, British ColumbiaSimon Fraser UniversityfalseKevin, M.J., M.J.
