A Rich Habitat for Birds

The avian diversity in Rocky Mountain National Park is a reflection of the park's varied habitats, which range from montane forests and alpine tundras to meadows and riparian zones along streams and lakes. Each of these environments supports distinct bird communities, offering ample opportunities for birdwatchers to observe a wide array of species.

In the lower elevations, the montane forests are home to numerous birds, including various songbirds, woodpeckers, and more. These forests consist mainly of lodgepole pine, Englemann spruce, and subalpine fir, creating a unique ecosystem that fosters various avian life. As you gain elevation, the landscape transforms, offering alpine meadows and rocky outcrops. The birds that thrive in these higher altitudes often exhibit remarkable adaptations to the rugged and harsh environments.
