Pinnacles National Monument provides a diverse habitat for numerous cliffnesting raptors, including prairie falcons, peregrine falcons and golden eagles, as well as a spectacular array of summits and cliff-wall routes for rock-climbers. This monitoring effort was established to determine long-term trends in the number of occupied territories and productivity of nesting prairie falcons. Data on presence and diversity of other nesting raptors are also collected. The effort grew out of a need to reduce potential disturbance that climbers and off-trail hikers may have on cliff-nesting raptors. This report summarizes the results from the 2010 breeding season and represents the 25th year of monitoring at the monument.
