Proceedings Ninth Bird Control Seminar, Bowling Green State University, Bowling Green, Ohio, October 4-6, 1983. Ed. William B. Jackson and Beth Jackson Dodd
Shoaf: Our next speakers are two gentlemen who will tell us about the work they have done in bird management on bridges. One is Russ Lemons of Rose Exterminating Company; and the other is Jim Cuming, the district manager of PCO Services Ltd. in Windsor, Ontario, Canada. They will give us some valuable ideas on what can be done, and what has been done in the past.
Lemons: My experience in bird control has included all the legal chemicals and toxicants that we can use. Years ago, before EPA, I used to mix my own chemicals: ammonia, Tide, and alcohol, which made something similar to Tergitol. Now it wouldn't be allowed. The type of bird you wish to control on the bridge will determine what to use, whether it's baiting, exclusion, repellents such as sticky materials, or noise alarms. You also can spray with PA-14, which is Tergitol. A lot of those materials are not practical on bridges; but, of course, it depends on the design of the bridge. This morning we are going to discuss the Ambassador Bridge, which connects Canada and United States between the cities of Detroit and Windsor. Jim Cuming designed the plan to control starlings, which are very bad on the bridge between October and March.
Cumlng: A request to remove roosting nuisance birds from a bridge structure is not frequently made; however, when PCOs are called upon to alleviate such problems, they need to have some answers. They should first examine all alternatives, which include:
1. No action.
2. Moving roosts through repellents.
3. Moving roosts through habitat manipulation.
4. Trapping at feeding or loafing sites.
5. Trapping at roosting sites.
6. Bird proofing.
7. Reducing bird populations at feedlots through baiting, i.e., Avitrol,strychnine, etc.
8. A combination of alternatives.
9. Use of alarm systems - Av-Alarm
As a final alternative, determine if the use of PA-14 (Tergitol) is the most appropriate technique.
