Bird/wildlife deterrent devices can be broadly divided into visual, acoustic and lethal, and subdivided into portable and static systems. The levels of sophistication, and hence cost, available are highly variable and include the simple scarecrow, (a static visual device), complex radio controlled sound generators (static acoustic), pyrotechnic pistols and vehicle mounted distress call apparatus (mobile acoustic), hand held lasers (mobile visual), traps (static lethal) and a shotgun (mobile lethal). The choice of which systems, or combination of systems, to deploy will depend on cost, legal and logistical constraints and, perhaps most importantly, on the species that need to be dispersed. For example, attempting to use a **distress call system** on a bird species which do not produce such calls is doomed to failure.
