Quick Answer
Male Ruffed Grouse are larger and have a distinctive "drumming" display, while females are smaller and have a softer, more muted plumage. The males' black throat feathers are also more prominent, and they have a more pronounced, rounded tail. In addition, the males' eyes are more intensely colored.
Physical Characteristics
When it comes to physical differences, male Ruffed Grouse typically weigh between 1-2 pounds (0.45-0.9 kg) and measure 23-26 inches (58-66 cm) in length, while females usually weigh between 0.7-1.4 pounds (0.32-0.64 kg) and measure 20-23 inches (51-58 cm) in length. The males’ black throat feathers are a distinctive feature, and they have a more prominent rounded tail with 14-16 tail feathers. Females, on the other hand, have a softer, more muted plumage with a mix of black, gray, and brown feathers.
Behavioral Differences
One of the most notable differences between male and female Ruffed Grouse is their behavior, particularly during the breeding season. Males are known for their distinctive “drumming” display, which involves beating their wings against their tail feathers to create a low-pitched drumming sound. This behavior is used to attract females and establish dominance. In contrast, females are generally more solitary and spend their time foraging for food and tending to their young.
Habitat and Distribution
Both male and female Ruffed Grouse inhabit similar habitats, including deciduous and mixed forests, as well as shrublands and woodlands. However, males tend to occupy larger territories during the breeding season, which can range from 20-40 acres (8-16 hectares). Females, on the other hand, will often occupy smaller territories and may overlap with other females. During the winter months, both sexes will often congregate in areas with dense vegetation and reliable food sources.
