Colorado’s elevation range - from 3,300 feet on the plains to over 14,000-foot peaks - creates stacked habitat zones that support different red-plumaged species at different altitudes. House Finches are common in the lowlands, Red Crossbills work the mountain conifer forests, and Pine Grosbeaks live at high elevations.
