Parents and pet owners in Melbourne’s Western Suburbs have been warned of a potential poison threat.

It follows the unexplained death of multiple magpies in the area, with five being found dead within 15 metres of each other.

The birds were all taken to Werribee Zoo, who will now conduct examinations to determine how they died.

It is believed that the magpies could have been poisoned but it’s not known if it was intentional.

One of the birds was rescued and made a full recovery.

“We are working on a release plan for this bird given she had most likely lost all her family,” Point Cook Wildlife Care said in a Facebook post.

Point Cook Wildlife Care has urged residents to contact them if they see birds in the area not moving and with their wings splayed.
