The NSW Environment Protection Authority (EPA) is seeking information from the Blue Mountains community in relation to a series of suspected bird poisonings in Katoomba.
This follows the discovery of approximately 38 sick or dead birds – including cockatoos and rock doves – within 100 metres of Katoomba's Pryor Place over the last three weeks.
Executive Director Operations Jason Gordon said the EPA is investigating potential pesticide misuse as the cause of illness and death in the birds, after bird seed found outside Katoomba retail shops and on the roof of the Katoomba Town Centre Arcade tested positive for the restricted pesticide alphachloralose.
"Alphachloralose is subject to an EPA Pesticide Control Order due to its toxicity and potential for misuse, meaning there are strict limitations around who can use the pesticide and how," Mr Gordon said.
"Though alphachloralose is most often used as a pest control agent to target pigeons and mice, the pesticide is not available to the public and can only be used by people with a specific Pesticide Control (Possession and Use) Permit.
"Proper use of pesticides is crucial to prevent unintended harm to non-target animals and the environment, and heavy penalties apply for misuse.
"We urge members of the local community with any information about the suspected poisonings to make a report to our Environment Line on 131 555, as assistance from the public can be vital to investigations like these."
Investigations into the suspected poisonings are continuing in collaboration with Blue Mountains City Council.
The negligent use of pesticides in a manner that harms non-target animals or plants can attract maximum penalties of up to $500,000 for an individual and $2,000,000 for a corporation.
