Differentiating between starlings and grackles can sometimes be challenging due to their similar appearances. However, understanding their physical characteristics, behavioral differences, habitat, vocalizations, and potential sources of confusion can help you accurately identify these two bird species. According to the National Audubon Society, here’s a breakdown of what to look for when telling a starling from a grackle:
Physical Characteristics of Starlings:
Starlings are medium-sized birds with a sleek and slender body shape. They have short tails and relatively long, pointed wings. The most distinctive feature of starlings is their iridescent plumage, which shimmers with shades of green, purple, and blue depending on the lighting. They have a short and stout beak.
Physical Characteristics of Grackles:
Grackles are also medium-sized birds, but they have a more robust and stocky build compared to starlings. They have a long, keel-shaped tail and broad, rounded wings. Grackles exhibit iridescent plumage as well, but their colors tend to be darker, with hues of black, blue, and bronze. They have a long and slender beak.
Behavioral Differences Between Starlings and Grackles:
Starlings are known for their mimicry skills and can imitate a wide range of other bird vocalizations. They are highly social birds and often gather in large flocks. Grackles, on the other hand, have a distinctive “walk and pause” foraging behavior. They are also known for their raucous and loud calls.
Habitat and Distribution:
Starlings are commonly found in open habitats, including fields, meadows, and urban areas. They are native to Europe but have been introduced to North America. Grackles, on the other hand, prefer habitats near water sources such as marshes, swamps, and wetlands. They are native to North and Central America.
Starlings have a wide range of vocalizations, including musical songs and high-pitched whistles. Grackles produce a variety of sounds, including harsh, metallic calls and distinctive “grackle” sounds.
To facilitate identification, a side-by-side visual comparison of starlings and grackles can be helpful. Pay close attention to their body shape, tail length, wing shape, and iridescent coloration.
Sources of Confusion:
Despite their differences, starlings and grackles can sometimes be confused due to their similar sizes and iridescent plumage. their vocalizations may overlap, further contributing to the confusion.
By familiarizing yourself with these distinguishing characteristics and understanding the nuances between starlings and grackles, you can confidently identify these two bird species in various habitats and enjoy observing their unique behaviors.

Behavioral Differences Between Starlings and Grackles
When it comes to behavioral differences between starlings and grackles, there are several distinct characteristics that set them apart:
- Diet: Starlings have a more varied diet, feeding on insects, fruits, seeds, and even garbage. Grackles, on the other hand, primarily feed on insects and grains.
- Social behavior: Starlings are highly social birds, often seen in large flocks that communicate with each other through complex vocalizations and mimicry. Grackles, while also social, tend to be less vocal and prefer smaller groups.
- Mating habits: Starlings are monogamous birds and form long-term pair bonds. They typically have multiple broods per mating season. In contrast, grackles are known to be polygamous, with males often having multiple mates.
- Nesting behavior: Starlings build their nests in cavities, such as tree hollows or crevices in buildings, while grackles prefer to build their nests in trees or shrubs.
- Territoriality: Starlings are highly territorial and will defend their nesting sites aggressively against intruders. Grackles, on the other hand, are more tolerant of neighboring birds and will often feed and roost in larger groups.
In a true history, back in the 1800s, starlings were introduced to North America by Eugene Schieffelin, who wanted to bring all the birds mentioned in William Shakespeare’s works to the United States. He released 60 European starlings into Central Park in New York City. The starling population quickly exploded, and they spread across the continent. Today, starlings are considered invasive species and pose a threat to native bird species. Grackles, on the other hand, have always been native to North America and have naturally coexisted with other bird species. Their adaptable nature and distinct behaviors make them a fascinating subject for birdwatchers and researchers alike.
