A diverse group of birds congregates at the feeding station on a bright day. On the suet feeders to the left, a Red-bellied Woodpecker and a speckled European Starling take turns feeding. The main platform is crowded with Common Grackles and Red-winged Blackbirds. In the background, the partially frozen waters of the pond reflect the afternoon sun.

A busy afternoon at the feeders featuring several different species. A Red-bellied Woodpecker feeds steadily on suet on the left, while a Common Grackle moves around the center support. A male Red-winged Blackbird arrives on the right-side feeder, displaying its vibrant wing patches. For a short time, a speckled European Starling is also perched atop the left-most feeder.

A Blue Jay and a group of juvenile Common Grackles are busy feeding at the multi-station feeder. The Blue Jay occupies the left side of the tray, while the grackles are spread across the center tray and hanging feeders. Towards the end of the clip, an adult grackle with darker, iridescent feathers lands on top of the central post.

A male Red-winged Blackbird lands on the left side of the feeder tray followed immediately by a Common Grackle on the right. Both birds briefly forage through the seeds before the grackle takes flight, leaving the blackbird alone on the platform.

The bird feeder is a hub of activity on a bright June morning. A Red-bellied Woodpecker with its distinctive red crown and barred back perches on the left side of the tray. In the center, a Common Grackle displays its iridescent plumage and pale eyes. Several plain brown birds, identified as Brown-headed Cowbirds, forage for seeds alongside them. Meanwhile, a European Starling investigates a suet feeder in the background.
Jun 23, 2026
A very busy morning at the feeder station with several species feeding simultaneously. Male Red-winged Blackbirds are seen landing on the main tray and perched on the feeders, while several Common Grackles occupy the suet and tube feeders. A few European Starlings are also seen darting in and out, primarily targeting the suet.
Geographic range
Where Does the Common Grackle Live?
Native to the North American continent, the Common Grackle is found extensively throughout the United States and southern Canada east of the Rocky Mountains. They are particularly abundant in the Great Plains and the eastern seaboard, with their range extending from the edge of the boreal forests in the north down to the Gulf Coast and Florida. While they are year-round residents in the central and southern parts of their range, northern populations are migratory, pushing south as winter temperatures drop to join massive communal roosts.

Behavior
Common Grackles are highly social and intelligent birds, often seen in large, boisterous flocks, especially during the fall and winter when they may congregate with other blackbirds and starlings by the thousands. They are bold foragers, often striding across lawns with a purposeful gait, scanning for insects or seeds. In suburban environments, they are frequent visitors to bird feeders, where their assertive nature and larger size often allow them to dominate smaller songbirds.
One of their most fascinating behaviors is 'anting,' where they allow ants to crawl through their feathers or rub crushed ants on their plumage to utilize the formic acid as a natural pesticide against mites. They are also known for their wide-ranging vocalizations, which include a variety of squeaks, rattles, and a signature metallic 'clink' that sounds somewhat like a rusty gate hinge opening. During the breeding season, males puff out their feathers and spread their tails in an impressive display to attract mates.

Camera Tips
To capture the best footage of Common Grackles, focus your camera on the ground. Unlike many songbirds that prefer hanging feeders, grackles are natural ground-foragers. Position your AI-powered camera 6 to 12 inches off the ground near a patch of open lawn or under an existing bird feeder. This low angle will highlight their confident 'strut' and capture the impressive length of the male's keeled tail as it drags through the grass.
Water is an incredible lure for this species. Grackles are frequent and enthusiastic bathers. If you have a shallow bird bath or a backyard water feature, aim your camera there. To get the clearest shots, place the camera on the north side of the water source so the sun is behind the lens; this lighting is essential to reveal the hidden blues, purples, and bronzes in their iridescent feathers, which often look flat black in shadows or harsh overhead light.
In terms of bait, Common Grackles are not picky, but they are particularly fond of cracked corn, suet, and black oil sunflower seeds. Using a flat platform feeder or simply scattering seed on a flat rock will keep them in the frame longer than a tube feeder would. Because they are social, you are likely to capture multiple birds at once, so set your camera to a wide-angle view if possible.
For settings, prioritize a fast trigger speed and burst mode. Grackles are jerky, fast-moving birds that constantly scan their surroundings. A video setting of 30 or 60 fps will help you catch their quick head movements and the 'puffing' displays of the males during the spring. Early morning and late afternoon offer the best 'golden hour' light to make their metallic plumage truly pop against a green backyard background.
