Habitat - These types of forests occurs across the continent as a wide belt extending from New England and southern Canada northward to the Arctic Tundra, westward to the Pacific coast, and southward through the Rocky and Sierra mountains. In some areas a single conifer, such as ponderosa pine, dominates the vegetation. Coniferous Forests may be composed of pines in the east, black spruce in the north, redwoods in the southwest, or Sitka spruce in the west.
Within the Coniferous Forest belt occurs large stands of mixed conifers. On the Pacific coast these may include associations of Douglas-fir, western redcedar, and western hemlock while in the north firs and spruces may be found together. As a rule, these kinds of forests support a greater variety of birds than do pure coniferous forests.
Most singing activity occurs during the breeding season which may extend from February in the south to August in the north. Some birds, like the Winter Wren, Pileated Woodpecker, and Common Raven can be heard throughout the year in this habitat
