A red stag, taken with a rifle. A brace of red grouse, taken on the wing. A wild Atlantic salmon, taken on the fly. By one person, in one day, on the same ground, between sunrise and sunset.

The seasons only overlap from mid-August to mid-October — a narrow window when stag, salmon and grouse can all legally be in pursuit at once. The Field tracks notable Macnabs every season. Variants exist: the Royal adds a right-and-left at grouse; the Imperial adds extra species; the Solo is done without a ghillie. But the classic three are the ones that count.
