Augustine Island (Cook Inlet), Kodiak Island, the Barren 

 Islands, and the Kenai Peninsula (Day and others 1983, 

 Mendenhall 1992, Simons 1980). All of these nests were 

 located in areas of talus where surrounding rocks formed a 

 protected area for the nests, or in areas dominated by 

 alder. The egg was laid on existing mat vegetation or bare 

 soil. Whereas most of these sites were above the local tree 

 line and had only low-lying mat vegetation, the Kenai site 

 had a forested area on a nearby slope. An additional ground 

 nest found on Prince of Wales Island in southeastern 

 Alaska in 1993 was located on a platform of moss covering 

 three intertwined roots of a western hemlock (Tsuga 

 heterophylla) tree at the top of an 11 -meter high cliff 

 (Ford and Brown 1994). The nest had many of the 

 characteristics of a tree nest when approached from down- 

 slope, but was similar to a ground nest when approached 

 from up slope. 



Methods 



We compiled information from 61 nest stands and nest 

 trees throughout die geographic range of the Marbled Munelet 

 in North America using published and unpublished 

 information. Information from three additional tree nests in 

 Alaska were not obtained for this review. We did not include 

 data from ground nests in this summary. We summarized 

 tree and stand characteristics from 14 tree nests in Alaska 

 (Naslund and others, in press), nine nests in British Columbia 

 (Burger, pers. comm.; P. Jones, pers. comm.; Jordan and 

 others in press; Kelson, pers. comm.; Manley, pers. comm.; 

 Manley and Kelson, in press), six nests in Washington (Hamer, 

 unpubl. data; Holtrop, pers. comm.; Ritchie, pers. comm.), 

 22 nests in Oregon (Nelson, unpubl. data), and 10 nests in 

 California (Binford and others, 1975; Chinnici, pers. comm.; 

 Folliard, pers. comm.; Hamer, unpubl. data; S.W. Singer, 

 pers. comm.; Singer and others, 1991) (table 1).
