 | | Elevation is the determining factor in locating and identifying the variety of plants and animals found in Rocky, and the park can easily be divided into three main zones: the montane ecosystem, at lower elevations; the subalpine, at the midlevels; and the alpine, at the park's highest elevations. |
 | | The warmest part of the park, because it is at the lowest elevation, the montane ecosystem has the greatest variety of wildlife. |
 | | Watch for colorful mountain bluebirds, among the earliest of the park's seasonal residents to arrive, as well as the distinctive red-napped sapsucker, western tanagers, fl-billed magpies, and warbling vireos, which can sometimes be heard singing from their nests in aspen trees. |
