Nearly a dozen volunteers braved below-freezing temperatures on February 25 for the annual cleaning of Energy Northwest's artificial burrowing owl habitats.
The 10 volunteers, which included EN employees, their spouses and children, and retirees inspected and cleaned the burrows before the migratory owls return to begin their spring nesting.
Burrowing owls are listed as a Species of Greatest Conservation Need in Washington state; in fact, sightings of the owls outside of Benton, Franklin, Grant, and western Adams counties are rare.
Contrary to its name, the Western burrowing owl does not dig its own burrows but rather takes up residence in burrows left behind by ground squirrels, prairie dogs, foxes, badgers, and coyotes.
As habitat for these mammals shrinks so does the available abandoned burrows for the burrowing owls.
Energy Northwest partnered with the Washington Department of Fish and Wildlife in 2012 to install 9 sets of burrows near Columbia Generating Station and employees have maintained them since 2016.
The burrows are managed by the Energy Services and Development Environmental Services team.
Each set includes 2 burrows — 1 the owls use for nesting and the other where they store their food supplies — and a low perch where the owls watch for predators.
Volunteers created each artificial burrow from half of a 55-gallon drum and a 5-gallon bucket serves as a maintenance hatch. A 6-inch tube leading from the drum gives the owl access. The burrows are buried to look like normal animal burrows.
