Using nest records and locations to identify landscape-scale parameters (distance to coast, elevation, slope, and land cover) that provide potential nesting habitat, we produced a final map classifying 12% (70,411 km2) of the lands assessed as potential Kittlitz’s Murrelet nesting habitat with dense but distinct patches located in northern Alaska and a more uninterrupted, narrow band extended across coastal mountainous areas in the Pacific Coastal Mountains, Alaska Peninsula Mountains, and Aleutian Islands. The regional variation in habitat-capable parameter values indicate the Kittlitz’s Murrelet may be able to use a variety of habitats for nesting depending on availability. Future nesting habitat studies that...

The Kittlitz’s Murrelet (Brachyramphus brevirostris) is a small, non-colonial seabird endemic to marine waters of Alaska and eastern Russia that may have experienced significant population decline in recent decades, in part because of low reproductive success and terrestrial threats. Although recent studies have shed new light on Kittlitz’s Murrelet nesting habitat in a few discrete areas, the location and extent of other possible nesting areas throughout most of its range remains unclear. This data release consists of (1) nest locations for the Kittlitz’s Murrelet (2) potential Kittlitz’s Murrelet nesting habitat. These data support the following publication (available online early): Jonathan J. Felis, Michelle...
