UAF - Kittlitz's Murrelet Known Nest Locations in Alaska (GIS layer)Entry ID: ArcOD_2005O2
Abstract: The Kittlitz's Murrelet Brachyramphus brevirostris is a bird species of environmental concern, and only 21 confirmed nest locations are published for North America. Drastic population declines are reported in its southern distributional range. This bird is found in subarctic and warmer regions near glaciers, also occurring in Russia. A wider analysis of these nest sites is coming forward, and it appears that these nests are associated with glaciers and volcano slopes. However, this is only an impression based on the small sample of nests.
Purpose: The purpose of this dataset is to learn more about the Murrelet Brachyramphus brevirostris since only 21 nest locations are known in North America. This dataset presents the baseline for a predictive modeling exercise.
SUPPLEMENTAL INFORMATION: This species also occurs in Russia, but only few details are known. The species is reported to have undergone drastic declines during the last 20 years, likely due to global change, e.g. glacier retreat.

Quality COMPLETENESS REPORT: Caution is to be taken when interpreting these nest locations because the sample size is extremely low, and nests were found in a somewhat opportunistic fashion. For use and interpretation of this data set, please contact experts.
PROCESS DESCRIPTION: GIS The data presented here are derived from a species account (Day et al. 1999) and geo-referenced in Arc View 3.3. They can be used for further analyzing and modeling in a Geographic Information System (GIS).
