''Amphibian translocation programs: reply to Seigel and Dodd.
Irruptions southward are probably related to food shortages.The boreal chickadee is one of the few songbird species found almost exclusively in boreal forests of Canada and adjacent areas of the US. Flocks of six to 12 chickadees roam over winter feeding ranges of about 40 acres, regularly visiting known food sites.
",Species Account Citation: AmphibiaWeb 2020 Anaxyrus boreas: Western Toad <.Declines and or possible extinctions have been reported for populations in the Sierra Nevada, Colorado, New Mexico, Oregon, Utah, and Wyoming (Stebbins and Cohen 1995).
Belly white with small black spots. The boreal’s common call is similar to that of other chickadees — chick-a-dee-dee-dee — but is slower and more nasal.Territorial during the breeding season, chickadees flock during the rest of the year. A chickadee can put on eight percent of its body weight in fat each day. Birds burn fat as fuel to keep warm in winter.
The future stability of populations depends on maintaining mature stands of spruce in boreal forests and curbing the effects of climate change.Board of Fisheries and Game: Actions & Activities,Alaska Resources Library and Information Services (ARLIS),About the Division of Commercial Fisheries,Western Alaska Salmon Stock Identification Program (WASSIP),Online General Season & Registration Permits,Subsistence and Personal Use Fishing Permits,CSIS – Community Subsistence Information System,The Technical Papers and Special Publications Series.
Both sexes have warty skin and oval parotoid glands. Usually the female begins excavating the cavity with some assistance from the male. Along with two other subspecies, it is found across the Pacific Northwest from southern California to Alaska.

Try finding a boreal toad in bunchberry! The Montana form of the western toad is known as the boreal toad.
The birds usually roost in dense conifers but may also roost in cavities, under eaves of houses or other protected sites.Chickadees are specially adapted to endure Alaska’s rugged winters. It prefers high-altitude wet habitats (8,000–12,000 ft in elevation) such as lakes, marshes, ponds, bogs and quiet shallow water Habitat selection for western toads is important because they require open water for breeding, and they can die if they are too exposed to seawater. We used a landscape genetics approach to quantify the effects of landscape features on gene flow and connectivity of boreal toad (.Please note: The publisher is not responsible for the content or functionality of any supporting information supplied by the authors.
