HC Deb 26 January 1956 vol 548 c58W
Sir A. Bossom

asked the Minister of Agriculture, Fisheries and Food what progress had been made in the experiments with the use of poisonous or stupefying substances for killing pigeons or other bird pests.

Mr. Amory

Preliminary field trials have shown that it is possible to catch rooks, jackdaws and feral pigeons with narcotised baits. Trials against wood-pigeons have been less successful but efforts to find effective baits for these birds are continuing.
