The bird described as black with a blue head is the Steller’s Jay, a highly recognizable large songbird native to the coniferous forests of the western United States. Its two-toned plumage perfectly captures this description. The visual contrast of the dark upper body against the vibrant lower body makes it stand out among other birds in its range.
Primary Identification The Steller’s Jay
The Steller’s Jay, scientifically known as Cyanocitta stelleri, is the only crested jay in western North America. Its coloration is a dramatic gradient that visually separates its body into two distinct color zones. The head, prominent crest, nape, and upper chest are covered in deep black or charcoal-colored plumage, forming a distinctive “hood.”
This dark hood establishes the “black head” part of the description, appearing as a dark, solid cap. The black then transitions abruptly around the mid-body, giving way to a vivid, rich cobalt blue that covers the wings, lower back, and tail feathers. The wings and tail often feature subtle black barring against the bright blue.
The tall, shaggy black crest rises from the top of the head, giving the bird a large, assertive profile. This bold coloration and prominent crest make the Steller’s Jay conspicuous, especially in the dark shadows of a dense evergreen forest. It is a hefty songbird, measuring approximately 12 to 13 inches in length.
Confirming the Sighting Distinctive Features and Behavior
Beyond its striking coloration, the Steller’s Jay has several other characteristics that aid in confirming a sighting, particularly its size and loud vocalizations. It is large for a songbird, possessing a sturdy body, rounded wings, and a long tail. Its substantial size and confident posture make it easily noticeable.
The Steller’s Jay is famously noisy, announcing its presence with a harsh, raspy call often described as “shack-shack-shack.” It is also an accomplished mimic, frequently imitating the calls of raptors, such as the Red-tailed Hawk, likely to scare away smaller birds and claim food sources. This loud vocalization is often heard before the bird is seen.
These jays are intelligent, inquisitive, and bold in their behavior. They are omnivorous and opportunistic foragers, comfortable exploring both the high canopy and the forest floor. They are common around human activity, often frequenting campgrounds, picnic areas, and bird feeders where they scavenge for seeds, nuts, and food scraps.
The preferred habitat is the evergreen and mixed-wood forests of western North America, spanning from Alaska down to Central America. They are often found at higher elevations in the mountains, though they can be seen at lower elevations along the Pacific coast. Their long legs allow them to move with bold hops on the ground as they search for food.
Regional Variations and Look-Alikes
The appearance of the Steller’s Jay is not completely uniform across its vast range, as ornithologists have described numerous subspecies with slight differences in plumage. Birds in the Rocky Mountain interior, for example, often display distinct white streaks or a partial white eyering on the black crest. Coastal populations typically have darker, pure black heads with blue streaks or no light markings at all.
The variability in the extent of black and blue can sometimes lead to confusion with other species, particularly the California Scrub-Jay. The Scrub-Jay has a blue head and wings, but its chest and throat are typically gray or white, lacking the dark black hood of the Steller’s Jay. This contrast is the key distinguishing feature between the two species.
Another potential source of misidentification involves highly iridescent blackbirds, such as the Common Grackle and Brewer’s Blackbird. These birds appear entirely black from a distance, but in direct sunlight, the males exhibit a dramatic structural color. The Common Grackle, for instance, has an iridescent head that shimmers with a glossy purple-blue, while the body may reflect a bronzy color.
These iridescent blackbirds are generally found in different habitats than the Steller’s Jay, often preferring open areas, agricultural fields, and suburban lawns in the eastern and central parts of North America. Despite these look-alikes, the Steller’s Jay’s combination of a prominent crest and a solid black hood fading into a deep blue body remains unique to the specific visual query.
