Worldwide Species Action Plans

Mountain Bluebird action planMountain bluebird (Sialia currucoides) populations have been relatively stable across their range over the past 40 years. However, local declines have apparently occurred in some areas along the eastern foothills of the Rocky Mountains, as well as in the Black Hills of South Dakota and Wyoming. Mountain bluebirds breed in a variety of habitats characterized by open ground or short grass with nearby tree cavities for nesting. Consequently, the primary conservation consideration for mountain bluebirds is the availability of mature trees in proximity to open habitat. A large number of studies have now shown that mountain bluebirds show relatively strong affinities to habitats impacted by fire and logging; their abundance typically increases significantly in such habitats. It is likely then that widespread fire suppression in western forests has negatively impacted the abundance of mountain bluebirds. While logging may create nesting habitat for mountain bluebirds, there are limited data suggesting that nesting success may be low in logged areas. A better understanding of the relative quality of mountain bluebird breeding habitat would simplify habitat management efforts for this species. For example, studies of bluebird breeding success in natural cavities in recently burned forest, on logged sites, and in undisturbed situations would help to clarify the role of these habitats in determining population viability.
