The signs are designed to alert people about the problems associated with feeding wildlife items such as bread and seeds.
Residents and City officers have noted that people are feeding birds at popular foreshore areas and although they are being fed with good intentions, the actions can lead to sickness and disease.
Canning Commissioner Linton Reynolds said feeding birds human food could also affect water quality in the Canning River because bread and other food left in the water would significantly increase nutrient load.
‘The City of Canning encourages people to visit and enjoy the foreshore, which is one of the many wonderful natural areas within the City,’ he said.
‘We would like to remind people that feeding birds is not healthy for the birds or the environment.’
The new sign is on the Canning River foreshore, in the western bank between Shelley Bridge and Riverton Bridge.
This area was highlighted as a bird feeding hotspot by nearby residents and City officers.
