Known Ground reconstruction — not personally tested
Escoffier's historical formula specifies wild duck directly.
The source bird remains wild duck. A hot oven replaces the spit, while lemon and watercress remain the only garnishes.
Instructions
1. Heat the oven to 475°F with a small roasting pan inside. Season the duck inside and out with salt and pepper.
2. Set the duck breast-side up in the hot pan and roast until the skin is browned and the breast, innermost thigh, and wing reach 165°F (74°C), checking early because wild birds vary greatly in size.
3. Rest for 10 minutes, then carve. Arrange lemon halves and watercress around the bird and serve immediately.
Historical formula
Escoffier says wild ducks are not covered with bacon and are roasted before a fierce fire. He directs that wild duck remain underdone, gives about twenty minutes for roasting, and serves it surrounded with lemons and watercress.
Source note

Historical source vs. current safety guidance
Escoffier directs that this bird remain underdone. The Known Ground reconstruction instead follows current USDA guidance to cook duck and goose to 165°F (74°C), checked in the thickest breast and innermost thigh and wing without touching bone.
