North Clear Creek Falls (San Juan Mountains)

Well-photographed famous waterfall in Colorado. This waterfall is a confirmed nesting site for the Black Swift, listed as a Species of Special Concern by the U.S. Forest Service and U.S. Fish and Wildlife Service. The swifts migrate from Brazil annually to occupy this site from late May until late September, raising a single chick. The swifts are susceptible to disturbance from human activities near their nests, including noise and movement, direct disturbance or destruction of their nests, and trampling of vegetation. Canyoneering/climbing at this waterfall during the Black Swift nesting season (late May - late September/first frost) is likely to cause direct damage to nests, eggs, and young, and disturb adult swifts enough to cause them to abandon their nest and offspring.
