Black Swifts use crevices and ledges for nest sites. Their nests are typically associated with waterfalls that have limited light. They forage over large areas and at high elevations.
Limiting factors
Given their strict nesting requirements, Black Swifts are limited in their distribution and uncommon in Oregon.
Data gaps
Survey potential nesting areas to identify nesting sites.
Conservation actions
Limit human disturbance and habitat alteration to waterfall nesting locations. Minimize disturbance or alteration to surrounding forestlands. Maintain water flow at occupied sites. Improve detection methods.
