Colorado’s eastern plains are the ideal environment for birding in Colorado, thanks to the astounding variety of birds that make homes in the area's rolling grassland, craggy rimrock, secluded ponds and cool streams edged with cottonwoods and willows.
Colorado is home to more than 450 different avian species, many of which are found in the diverse ecosystems just east of the Rocky Mountains. Here, lone falcons share the sky with droves of tiny white-throated swifts, owls snooze inside hollowed trees and prairie chickens strut through vast stretches of golden shortgrass.
With such wide-ranging terrain and varied wildlife, the area is a renowned destination for avid birders. The Colorado Birding Trail is a large-scale initiative that identifies prime birding areas in Colorado, both public and private, where visitors can see the state's beautiful birds. Grab your binoculars and follow the call of the wild with this sampling of birding trails.
