Bird Scaring

Predator Bird Calls

Many species of birds have a “distress call”. These are sounds that the birds transmit only when they are being attacked by a predator. Distress scaring systems have a recording of the distress call of the pest bird, which is played back through a series of loudspeakers. Broadcasting distress calls elicits different reactions in different species of pest birds. Social and aggressive birds that communicate verbally within colonies, such as gulls and corvids will usually fly towards the source initially to see if they can mob the predator and help their kind. When the call ceases and they do not find a predator they are then unnerved or ‘scared’ by the possible danger and disperse. Birds that do not communicate much verbally or do not have bills or claws to threaten predators such as pigeons or starlings will tend to stop and assess the situation then disperse. The best results come from the distress calls of the actual pest bird species causing the problem.

The pictures bellow show a flower silo where Enviroguard recently fitted a scaring system against gulls and starlings.

Enviroguard supply a wide range of Audio Distress Systems for different situations and can advise on the most suitable for your specific bird problem.
