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 Colorado's native prairie, which once covered nearly half the state, remains now only in patches, many of those on the Pawnee and Comanche National Grasslands. Sometimes the avifauna provides the best indicator of how "native" a particular patch of prairie is. McCown's Longspur and Mountain Plover tend to be associated with the highest-quality patches. Chestnut-collared Longspurs can be found in small areas with slightly longer grass, sometimes called mid-grass prairie, on the Pawnee. Other typical prairie birds include Burrowing Owl, Horned Lark, Grasshopper Sparrow, Lark Bunting and Western Meadowlark.
