Deterrent Information – Birds of Prey

 IMPORTANT NOTE: Legal Protections for Birds of Prey (Eagles, Hawks, and Owls)

 HAWKS, OWLS, and EAGLES are protected under the Migratory Bird Treaty Act and other federal and state laws. They cannot be harassed, captured, harmed, or killed without a permit. In addition, BALD and GOLDEN EAGLE nests and nest sites are protected under the federal Bald and Golden Eagle Protection Act. Hazing with gunfire, explosives, and airplanes is prohibited without a permit. Consult the U.S. Fish and Wildlife Service or the Oregon Department of Fish and Wildlife for specific regulations.

 EAGLES

 Bald Eagles can be attracted in large numbers to large-scale pastured poultry operations. Newborns are very vulnerable during birthing seasons. Eagles will also prey on 3- to 4-week old lambs and kids as they begin to wander or play farther from mothers, but not generally after 6 weeks of age. Golden Eagles are more of at threat to older lambs and kids than Bald Eagles, but there are only a few Golden Eagles that spend late February to early March in the Willamette Valley.  Golden Eagles leave the Willamette Valley by the end of March.

  •  Set up birthing sheds or protected pens less than 1 or 2 acres in size. Temporary pens for night and early morning are very useful since eagles are unlikely to enter smaller spaces.
  •  Use livestock guardian animals, particularly dogs that alert to aerial attacks. Livestock guardian animals are more effective in areas small enough for them to actively protect, rather than very large spaces with scattered stock or poultry.
  •  Provide brushy grazing areas and shelters, which are safer than large open pastures with no overhead protection to deter aerial attacks.
  •  Provide an active herding and human presence to discourage eagles.
  •  Remove all carrion. Do not feed eagles to attract them away from pastured livestock.  This practice will attract other carnivores to the area.
  •  Mount or suspend clothed scarecrows, with movable arms, on high points near nightly bedding areas, to scare eagles for up to 3 weeks (after which they become used to them).
  •  Use portable electric netting to subdivide large pastured poultry areas.
  •  Use netting or wires over pastured poultry to disrupt aerial attacks.
  •  Use rounded corners in pens to reduce smothering during an attack.
  •  Remove roosting sites for hawks, owls, and eagles.

 HAWKS

  •  Cover coops, runs, and pens well.
  •  Cover larger yards with grid systems or wire, reflective tape, Kevlar cord, or netting.
  •  Do not locate free-range areas near potential perching sites such as trees or poles. These areas should be provided with protective shelters. Outfit tall posts with electric pole shockers, metal cones, or spikes to discourage perching.
  •  Keep a rooster. Roosters often give useful alarms to their flock, providing time to hide in protective shelters or brush.
  •  Livestock guardian dogs will alert, bark, and charge at raptors.
  •  Use noisemakers, whistles, pyrotechnics, and gunfire to scare off hawks, until they become habituated.

 OWLS

  • Cover the top of the pen or coop with hardware cloth or tight mesh. Install wires or reflective tape to disrupt flight paths and areas of potential attack.
  •  For larger yards, set up grid systems of wire, monofilament, or Kevlar cord, covered with netting.
  •  Seal or cover all access around gates.
  •  Provide nighttime hiding places for free-ranging birds, waterfowl, and rabbits.
  •  Add a rooster to your flock, as a warning system.
  •  Avoid free-ranging sites with high perches (such as trees), although owls will also use fence posts.
  •  Use livestock guardian dogs if socialized to poultry for patrolling around poultry areas.
  •  Set up scare devices such as noisemakers, motion-activated sprinklers, lights, scarecrows, and reflective items. However, owls do become habituated to routines, lights, and many scare devices. Barred Owls, in particular, are attracted to lights to hunt for large insects.
