FIREFLY BIRD FLAPPER/ DIVERTER TESTINGOBJECTIVE:To Deter Birds from Nesting and Perching on Electrical Substation Equipment in Utah.LOCATION:Springville Power Company, in Utah County, Springville, UT. Springville Substation.GPS UTM Coordinate: 12 T Northing –0420406, Easting -4514055OBSERVER: Tim Chervick, Wildlife Biologist, Swift Creek Consulting – P.O. Box 111,Vernal, Utah, 84078.DATES:TIME:April 21, 2003 through Present Day.4/21/03 - 13:30 hrs. Test Started – On going through present day.METHOD:Six Firefly bird flapper units were mounted on lightning arrestor ground wires, at 6 sitesabove the electrical substation in May of 2003. A two-man crew with bucket truck wasused by Springville Power Company to install the Firefly units on the vertical groundwires.The Firefly Bird Diverter would start to rotate in 3-5 mph winds, making the unit veryvisible to resident birds, which at this site included numerous European starlings (Sturnisvulgaris) and one breeding pair of House Sparrows (Passer domesticus).The European starling flock would number from 25 – 75 birds throughout the day. Onepair of House Sparrows was nesting inside the office building adjacent to the substation.The sparrows would exit and enter a ventilation opening on the outside of the building.This vent was approximately 7 feet above ground level and 33 feet below and to the westof the top I-beam of the substation.RESULTS:Birds would watch the rotating product from perch distances of 25 – 50 feet or more. Perchsubstrates for wintering birds included the power feeder line for the substation and steel I-beam framework within the electrical substation facility.The six rotating Firefly Bird Flapper units were effective in hazing European starlingsperched on the substation feeder line pole located 25 feet due East of the substationfacility. The feeder line was approximately 30 feet in height above the flapper units.The substation site was visited on 10/16/2003, from 13:00 – 15:30 hours. Europeanstarlings were effectively hazed from perching on the I-beam facility structure.The House Sparrow breeding pair was not effectively hazed due to the location of the nestinside the facility and 33 feet below the top I-beam structure.


CONCLUSION:The Firefly product was effective up to 25 feet for hazing birds from perching on electricalsubstation structures, as long as the devices are installed properly to allow the flappers tofreely rotate in the wind. A total of six Firefly units were installed yielding a total hazingradius of 150 feet (6 units per 25 radius feet = 150 foot total radius coverage). The Fireflyunit must be installed at the bird’s eye level or above the bird in order to effectively deterthe bird from perching or nesting. This hazing radius is a horizontal effect when viewed bythe bird in line-of –sight. Hazing properties are not effective when the unit is placed belowthe bird’s feet and out of direct sight, or hindered by foliage or other obstructions.This product can be used as a non-lethal deterrent to bird perching and nesting inelectrical substation equipment.Footnote:The Firefly product is currently being tested by the Western Area Power Administration, atelectrical substations in Tracy, California – to deter Mourning Dove (Zanaida macroura)nesting and also at a WAPA electrical substation near Phoenix, Arizona – to deter RockDove (Columba livia) nesting.Figure 1.
