- Plumage: Male Bobwhite quails have a striking plumage pattern that helps them blend into their surroundings. Their upperparts are mottled brown, black, and white, providing excellent camouflage in their natural habitats. The feathers on their crown and nape are dark brown or black, and the sides of their head are white, creating a distinctive "mask."
- Chestnut throat and breast: One of the most noticeable features of male Bobwhite quails is their chestnut-colored throat and breast. This vibrant reddish-brown coloration is a key characteristic that distinguishes males from females.
- White belly: The belly of male Bobwhite quails is white, contrasting with their darker upperparts and reddish throat and breast.
- Black-and-white stripes on the sides: Male Bobwhite quails have prominent black-and-white stripes on the sides of their bodies. These stripes, also known as "flanking bars," are formed by alternating black and white feathers.
- Black-bordered white eyebrow: Above their eyes, male Bobwhite quails have a white eyebrow that is bordered by a thin black line. This feature helps accentuate their eyes and adds to their overall appearance.
- Long, dark tail: Male Bobwhite quails have relatively long tails compared to their body size. The tail is primarily dark brown or black, with a white tip that is visible when the bird is in flight.
Male Bobwhite quails typically have a body length of around 20-25 centimeters (8-10 inches) and weigh around 150-200 grams (5-7 ounces). Their physical features play an important role in courtship rituals, attracting mates, and defending their territories during the breeding season.
