Preventing Exposure
Various techniques can be used to disperse uncontaminated animals from a problem area or to concentrate and hold them in clean areas. Efforts to discourage unoiled birds from contaminated areas must be done early in the spill; these can include scare devices such as propane exploders and cracker shells, hazing with motorized equipment, or relocation through baiting at an alternative feeding area. No attempt should be made to disperse oiled birds since this can lead to introduction of oiled animals into uncontaminated populations.
For priority species, unoiled animals can be relocated through capture in cannon nets, drop nets, rocket nets, and swim-in or walk-in traps, and rapidly transported to “safe” areas.
