A typical 3 oz cooked serving of quail contains 21.3 grams of protein (25.1 g per 100 g), which makes it a very good source of protein. That covers roughly 43% of the 50 g reference Daily Value, so it can anchor a high-protein meal for the day.
Protein accounts for roughly 44% of the calories in quail, making it very protein-dense. The rest comes from fat and carbohydrate, so it adds a solid amount of protein while still carrying real energy - useful when you are eating to a calorie target rather than under one.
Among the 133 meats in the database, quail ranks 80th by protein per serving, and 121st out of all 796 foods on the site. Set against chicken liver, another meat entry in the database, a serving carries about 0.5 g more protein (chicken liver has 20.8 g per 3 oz cooked).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving above is measured by weight at 85 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
