Forbes Council voted on Thursday to write to the owners of the aviary advising them that noise levels taken at the facility are not in accordance with their approved development application.

Council conducted noise readings at the Calarie Road property after receiving a complaint in relation to "excessive noise caused by the birds".

The complainant claimed that every day, between 7am and 9am and 6pm and 8.30pm "excruciating sounds are created by the birds caged on the premises".

"The complainant claims that such noise constitutes an invasion of the peace and serenity of their place of abode, and requests that council direct the owners of the birds to take steps to prevent such noise reaching their dwelling to such an intensity," council’s environmental and planning director Paul Bennett wrote in a report to the council.

Mr Bennett reported noise readings were taken by council staff to determine if they were greater than 5dBA above the background noise level which was part of the development's consent.

On March 9 a reading of 13.9dBA was taken at 3.30pm followed by a reading of 13.5dBA at 8.07 on March 11 and a reading of 8.3dBA at 7.14pm on March 15.

Council recorded a reading of 3.1dBA at 7.08pm on March 30 and 18.0dBA at 7am on April 6.

"The readings taken indicate that with the exception of the reading taken on March 30 the noise levels are greater than 5dBA," Mr Bennett reported.

Moving the motion, which was passed unanimously, Cr Dennis Booth noted the readings in the morning were well above the permitted level of 5dBA.
