Quick Answer
To field identify male and female Spruce Grouse, note the presence of dark, iridescent feathers on the male, while the female displays a duller, more mottled plumage. Males also have a distinctive "crown" of feathers on their heads, whereas females have a more subdued appearance. Compare these characteristics with the bird in question.
Identifying Male Spruce Grouse
To distinguish a male Spruce Grouse from a female, observe the male’s dark, iridescent feathers on the neck, throat, and chest. These feathers often appear purplish or bluish in good light, and they can be quite striking. In particular, the male’s throat feathers, known as “drumming feathers,” are long and pointed, and they are a key identifying feature of the species.
Identifying Female Spruce Grouse
Female Spruce Grouse are generally duller in color than males, with a mottled appearance that helps them blend in with their surroundings. They lack the iridescent feathers of the males, instead displaying a more subdued plumage that ranges from brown to gray to tan. Females also tend to have a more rounded head shape than males, and their “crown” of feathers is less prominent.
Additional Tips for Identification
When attempting to field identify a Spruce Grouse, pay close attention to the bird’s size and shape. Spruce Grouse are relatively small, with a length of around 22-26 inches (55-65 cm) and a wingspan of around 25-30 inches (63-76 cm). They also have a distinctive, rotund body shape, with a short, rounded tail and a strong, powerful beak. By combining these characteristics with the presence or absence of dark iridescent feathers, you should be able to accurately identify a male or female Spruce Grouse.
