David Ross's report, RSPB blames estates as red kite poisoning soars (December 28), highlights the necessity for the "review of the investigation and prosecution of wildlife crime" announced by Environment Minister Michael Russell.

I would suggest that where a "land manager" is convicted of poisoning protected species (s)he would, as at present, be subject to the penalties prescribed by the Scottish Parliament. In addition, the estate owner should be held responsible for the actions of their employees. Perhaps the banning of shooting for a period of weeks at the height of the season would persuade rogue land owners that the killing of protected species has an adverse effect on the profitability of their estate.
