The Taiga is a belt of forest that runs across the boreal (sub-Arctic) latitudes of the northern Hemisphere. Coniferous trees dominate in the Taiga with various spruce, larch, fir and pine typical. Deciduous trees, which are more common in the primary and secondary succession stages of growth, are alder, aspen and birch. In Eurasia typical woodpeckers of this habitat include Eurasian Three-toed Woodpecker. In North America Black-backed and American Three-toed Woodpeckers are typical.
