Habitats and their associated birds Colorado is blessed with a tremendous variety of habitat types, which results in a tremendous variety of birds. In order to find a bird, you are best off looking for its habitat, and this requires at least a basic knowledge of Colorado's flora and geology. This section describes the main habitat types and some birds that are associated with them and may be hard to find elsewhere. Sagebrush Foothill Shrubs Spruce-Fir Forest Yucca Ponderosa Pine Forest Alpine Tundra Shortgrass Prairie Aspen Groves Cliff Faces Lowland Riparian Woodland Lodgepole Pine Forest Subalpine Life Zone Scrub Oak Woodland Streamside Willows Rimrock and Mesa Country Pinyon-Juniper Forest Ponderosa Pine (Pinus ponderosa) is typically the dominant tree from about 5500-8500 feet. It can be recognized at a great distance by its (usually) reddish bark, its long needles forming large ball-like clumps, its broad but sparse crown, and its tendency to grow widely spaced. Typical ponderosa birds include Flammulated Owl, Northern Saw-whet Owl, Williamson's Sapsucker, Plumbeous Vireo, Pygmy Nuthatch, Western Bluebird, Grace's Warbler (especially where there is an understory of Scrub Oak), and Western Tanager. Note that the owls and woodpeckers are best found where the ponderosas are interspersed with mature aspens.
