Behavior

McKay's Buntings are hardy Arctic specialists that spend their lives in some of the most extreme environments on the planet. During the winter months, they are highly social and nomadic, often forming large flocks that move in search of food across the frozen landscape. They are strictly ground-foragers, moving with a quick, walking gait as they search for seeds tucked into the snow or beach debris. Unlike many other songbirds, they rarely perch in trees, preferring the safety of open ground where they can spot predators from a distance.

These buntings exhibit a unique 'rolling' flock behavior when feeding. As the birds at the back of the flock finish searching an area, they fly over the birds in front to land at the leading edge, creating a constant forward motion. While they are generally shy, they can become remarkably bold in the presence of humans if a consistent food source like a bird feeder is provided during the lean winter months.

Camera Tips

Capturing a McKay's Bunting on camera is a badge of honor for any wildlife enthusiast. Because these birds are ground feeders, your camera should be mounted very low—no more than 6 to 12 inches above the ground. If you are in a coastal area of Western Alaska, position your camera near natural features like driftwood or patches of exposed beach grass, as these are the primary areas where the birds forage for seeds. Using a wide-angle lens is ideal, as it captures the dynamic movement of the entire flock as they move across the terrain.

Lighting is the most significant challenge when photographing this species. Their nearly pure white feathers are prone to 'blowing out' or overexposing, especially against a background of snow. To get the best results, aim your camera with the sun at your back during the 'golden hours' of the morning or late afternoon. This directional light creates soft shadows that help define the bird’s shape and the subtle buffy markings on females. If your camera settings allow for it, set a slightly negative exposure compensation to preserve the delicate texture of their white feathers.

To attract them to your lens, avoid traditional hanging feeders which they often ignore. Instead, create a 'ground station' by clearing a small patch of snow and scattering high-fat seeds like white proso millet, hulled sunflower seeds, or cracked corn. Because they are often found in high-wind environments, it is crucial to use a heavy, stable mount for your camera. A vibrating or shaking camera will not only result in blurry images but may also trigger the AI motion sensor unnecessarily.

Seasonal timing is everything. They are most likely to visit backyard setups during periods of heavy snow or extreme cold when their natural seed sources are buried. Look for them within larger flocks of Snow Buntings; the McKay's Bunting will always be the 'whitest' bird in the group. If you can position your camera near a source of open water or a heated birdbath, you may also capture unique behavior, as these birds frequently bathe to maintain the insulation properties of their feathers.

Similar Species

Species that look similar or are commonly confused with McKay's Bunting.

Snow Bunting

The Snow Bunting has a darker back with significant black or brown streaking, whereas the McKay's Bunting is almost entirely white.

Lapland Longspur

Lapland Longspurs are much darker and more heavily patterned, lacking the brilliant white plumage of the McKay's Bunting.

Frequently Asked Questions

McKay's Bunting are diurnal, meaning they are active during the day. During the limited daylight of an Alaskan winter, they forage intensely from sunrise to sunset to store enough energy to survive the freezing nights.

If you are within their narrow range in Western Alaska, scatter white proso millet or cracked corn directly on the ground in an open area. They prefer feeding on the ground rather than at elevated feeders.

In the winter, they eat seeds from various grasses and coastal plants. During the summer breeding season, they supplement this with insects and other small invertebrates found on the tundra.

No, they are quite rare. They are restricted to the western coast of Alaska and a few islands in the Bering Sea. They are occasionally seen near coastal villages but rarely move far inland.

Look at the amount of white on the back and wings. McKay's Buntings are much whiter overall, whereas Snow Buntings have more black, brown, and gray streaking across their backs and wings.
