The Airport Wailer MK IIIa Environment Canada "The following is an account of the effectiveness testing of the Phoenix Airport Wailer MK IIIa as a Bird Deterrent conducted at Yarmouth Airport. For clarification I am presenting this to you in the form of a technical report. The Phoenix Airport Wailer MK IIIa is very effective as a bird deterrent at airports and has the capacity to render its effective coverage area almost completely free of birds. From our experience it should not be considered to a bird scare device but rather as a bird deterrent system in that it appears to create and environment of sound that birds find uncomfortable which causes them to move away from the area slowly rather than being startled and moving out immediately. When properly deployed, the Phoenix Airport Wailer MK IIIa can be extremely effective in reducing bird numbers and thus bird strikes by aircraft at airports." R.G. Hounsell Bird Mitigation Officer Canadian Wildlife Service Transport Canada "Recently we completed a four-week, field trial on the Phoenix Airport Wailer MK IIIa. The unit was installed to cover 3000 feet of our main runway where we were having a problem with gulls. After the device was started it virtually sterilized that portion of the runway. There were no gulls observed in the area for the duration of the trial, but they returned the day after the unit was removed. The Phoenix Airport Wailer MK IIIa was very effective and the fact that it requires no propane, guns, or explosives makes it a safe, maintenance-free system and a plus in our opinion." R.
