Peregrine Watch

The number of known active Peregrine Falcon territories in Montana has increased dramatically from 0 in the mid-70s to 110 active territories in 2016. The accumulative number found active during the in survey years (1998-2018) is 224. Funding for surveys has dwindled since formal national surveys are finished We began project “Montana Peregrine-Watch” in 2010 to determine percent occupancy for our Montana Peregrine Falcon territories during these interim years between major surveys. In 2018, we had over 80 volunteers helping us monitor the Montana Peregrine Falcon territories.
