Animal welfare chiefs say they suspect that two birds of prey have been shot dead in the space of a week.
The Scottish SPCA is working with Police Scotland as they look into the incidents after a firearm was confirmed as being used in one of the Sparrowhawk's death.
One bird had to be put to sleep, while another was found dying with suspicious injuries which the SSPCA believe may be linked. A bird initially thought to have been stunned was found on Lochwinnoch Golf Course, Renfrewshire, on April 5 but its injuries were unsurvivable.
