How can I reduce the risk of guns shooting greys and on driven redleg shoots?

Tell guns what to look out for. Greys usually fly in coveys until they pair up in January, while redlegs may fly in large, more loose packs, but often in singles.

This alone may not be enough, so try to develop a system of signals from the beaters, and in particular the flankers, to warn guns of approaching grey partridges. Loud ‘thunderer’ whistles could indicate greys are coming so guns should only shoot if they are absolutely certain of redlegs over in the 15 seconds after a whistle blast. This technique has proved very effective.
