The City of Canning Natural Areas Team found the sick bird on May 22 after a Canning River Residents Environmental Protection Association (CRREPA) member reported it.
WA Conservation of Raptors members cared for the osprey, named Oskarlini, until June 20, when it was released at Bull Creek near where it was found.
Canning chief executive Lyn Russell said the relationships the city had established with environmental groups paid dividends .
�We have a group of environmentally engaged and educated residents who assist in the preservation of the natural environments around Canning,� Ms Russell said.
The City of Canning Natural Areas Team found the sick osprey in bullrushes in Bull Creek and took the bird to the raptors conservation group in Brigadoon.
More than 20 onlookers, including CRREPA members and city staff, watched as Oskarlini was released.
