The use of bird traps is an excellent way to reduce the bird population of most bird species prior to the installation of bird deterrent products. The flock can be reduced drastically without harming protected wild birds and minimizing public reaction. Many times bird removal is the only dispersal method available due to firearm and avicide restrictions. The trade off is time and effort. A successful trapping project takes several days and multiple journeys to the job site. Effective trapping entails proper site selection, pre-baiting, trapping, bird removal and follow-up. But it must be emphasized, flock reduction is only a preliminary step to deterrent product installation. If you remove birds but do not deter other birds, you will simply have new birds move into the vacuum you created.
