An ibis shot with an arrow and left to suffer for two weeks has been euthanased, sparking fears other animals in the north Brisbane area are being hunted.
The RSPCA received calls about the injured bird for about two weeks before it was able to be caught last week.
The ibis had to be put down as the arrow had caused irreparable damage to the abdomen.
"Our vets say the bird would have been in tremendous pain," said RSPCA Qld spokesperson Michael Beatty.
"The area was severely infected and the bird would have been living with this injury for up to two weeks."
A number of arrows were also discovered in the Caboolture area, and the RSPCA fears more ibis and other animals have been targeted.
