Quick Answer
Grouse can be distinguished from quail by their size, plumage patterns, and tail feathers. Grouse are generally larger and more robust, with a more rounded body shape, whereas quail are smaller and more streamlined. Grouse also have a longer, more rounded tail with a distinctive "brush" pattern, whereas quail have a shorter, more rounded tail.
Size and Plumage Patterns
When field identifying upland game birds, pay attention to size and plumage patterns. Grouse, such as ruffed grouse and spruce grouse, can range in length from 18-26 inches, with a wingspan of 24-30 inches. Quail, on the other hand, typically range from 9-12 inches in length, with a wingspan of 18-22 inches. Grouse also have a thick, grayish-brown plumage with a distinctive “barred” pattern on their breast, whereas quail have a more mottled, speckled pattern.
Tail Characteristics
The tail feathers of grouse and quail are also a key identification feature. Grouse have a longer, more rounded tail with a distinctive “brush” pattern, consisting of long, stiff feathers that give the tail a bushy appearance. Quail, on the other hand, have a shorter, more rounded tail with a more even, rounded shape. To observe the tail, approach the bird slowly and carefully, as sudden movement can cause the bird to fly away.
Behavioral Differences
Behavioral differences can also be used to distinguish grouse from quail. Grouse are typically more sedentary and will often remain in a fixed position when disturbed, whereas quail are more likely to fly or move quickly when approached. Grouse will also often “freeze” in place, relying on their camouflage and natural surroundings to remain undetected. Quail, on the other hand, will often move quickly and erratically, making them more difficult to follow.
