It has come up with the ideal gift for those shooting over the festive period – a wild grey partridge warning whistle, to help prevent greys from being shot accidentally during a redleg drive.

It’s the perfect present and the Trust says that every beater and flanker should be given one, as a ‘thank you’ gift for working on a local shoot.

The warning whistle has a really loud and distinctive sound, ideal for warning Guns of approaching grey partridges.

Much louder than a dog whistle, it’s audible even through hearing protectors.

The whistle is £2.60 and, together with a huge range of unusual Christmas gifts and cards, can be ordered from the Trust’s online shop at www.gctshop.org.uk www.gct.org.uk or telephone 0844 557 9630.
