It is important to provide continuous and varied time of day exposure of control techniques to geese to mitigate {1) habituation to control methodology and (2) decrease sense of security or rest. Intense control measures for first week or two designed to aggressively haze geese may be necessary. Control programs should be initiated at the first presents of geese and intensely continued until population begins to decrease.

Monitor other habitat areas to ensure geese do not re-establish in the vicinity of the control area, which could potentially create a new problem. A paintball gun is useful for marking birds to help with identifying where they may be relocating to and is an effective behaviour modification deterrent at the control site. Permission is required for marking birds from CWS.

Geese reacrwell to amplified distress calls which may initially activate a mob response within the population which can then be reinforce with pyrotechnical scare devices. Varied use of bangers, screamers and screamer flares (especially in low light operations) are most effective to disperse birds.

Other methods include placement of animated scare devices (decoy predators, flash tape, balloon eyes, bird in effigy) but caution must be taken to continually vary the type nd location of these devices as geese will quickly habituate to their presents rendering them ineffective. Th f predators, particularly dogs has also gained popularity as geese typically react positively to this con abituation does not easily occur as recognition of predators and avoidance is evolutionarily programme
