A recent spate of poisoning has been reported at Fullarton Woods, Troon, Ayrshire over the last month, apparently resulting in the death of one dog, one fox and possibly two buzzards. A second dog was poisoned but survived. Strathclyde Police are reported to have launched an investigation.
The first incident was reported in the Troon Times on 1 March 2011 and the Ayrshire Birding Forum on 2 March 2011. Rabbit baits laced with poison were discovered in Fullarton Woods on the Fullarton Estate (this is not a sporting estate – it is a public amenity run by South Ayrshire Council that includes a play-park for children). A local resident’s dog was poisoned but made a recovery. Two dead buzzards were apparently discovered, although it has not been confirmed if they had been poisoned.

OK Just for some readers interest…I would be interested in the adjacent Golf Course [if theres no shooting in these public access woods.Perhaps not widely known but greenkeepers hate foxes, as they have a habit of digging for worms on well kept greens and fairways [yes. worms…like the buzzard that “savage predator” the fox, regularly eats invertebrates]
In the bad old days [these modern days are just as bad, as statistics show!] of the 1970s and early 80s many scottish golf courses bought and used horrible poisons such as Phosdrin/Mevinphos [there is documentary proof of this] to kill foxes.
In the absence of knowledge of any other motive…that would at least be one line to follow.
