Results/Conclusions Research suggests that snowy owls migrate south in higher numbers when there is a colder winter, and less prey availability up north. The owls' migration patterns may also follow a cyclical population fluctuation of their primary prey, the lemming. Owls prefer sites on the Maine Coast that have a significant amount of open space, including bare rock and/or short (< 1m.) vegetation. These conditions are common on high ridge tops and also on many off-shore islands. Unfortunately, this has the potential to draw owls into areas that are favored for wind-turbine development in both terrestrial and mid-water habitats.
