The owner of a macaw parrot found on Caerphilly Mountain is being urged to come forward by the RSPCA.
The animal welfare charity said it was unusual that nobody had come forward to claim the bird since it was found on Friday.
The RSPCA has not issued a photograph of the bird as it wants the owner to describe its striking colours before it will be handed over.
A spokesperson said the birds can be worth a lot of money.
Anyone who may have information can contact the RSPCA appeal line on 0300 123 8018.
