Boat-Tailed Grackle (Quiscalus major) lives in freshwater marshes across Southeastern United States. It feeds on insects and seeds. Its conservation status is Least Concern.
Fascinating facts about the Boat-Tailed Grackle
- In Gulf Coast towns boat-tailed grackles have formed sizable urban colonies that nest close to human dwellings. They take advantage of human activity, which offers protection from predators, and they regularly scavenge in trash bins, parking lots and outdoor restaurant patios. These birds are permanent coastal residents, preferring salt-marsh habitats but thriving where people provide food waste.
- Male boat-tailed grackles defend a harem of closely nesting females, but genetic studies reveal that only about a quarter of the chicks carry his DNA. The species builds a well-concealed cup nest in trees or shrubs near water, and the average clutch contains just over three eggs. Females often leave the colony to mate with other males, resulting in most offspring being sired elsewhere.
- The colour of a boat-tailed grackle's eye changes with its geographic range, providing a subtle regional marker. Birds living on the Gulf Coast and further inland have dark irises, whereas individuals along the Atlantic shoreline display pale eyes. This variation is noted across the species' distribution from the southeastern United States up the Mid-Atlantic coast. Eye colour therefore correlates with the bird's location rather than with age or sex.
- Male boat-tailed grackles are strikingly glossy black, their feathers shimmering with iridescence that catches the light over coastal marshes. They measure between 37 and 43 cm in length and carry a weight of 165-250 g, giving them a solid presence on the water's edge. Their long dark bill and pronounced keel-shaped tail complement a wingspan of 39-50 cm, while the tail itself ranges 11-20 cm long.
- Boat-tailed grackles are bold foragers, hunting on the ground, wading in shallow water and moving through low shrubs as they search for food. They are notorious thieves, snatching bites from other birds, small animals and even people, which broadens their already varied diet. As omnivorous opportunists they consume insects, crustaceans, minnows, frogs, eggs, berries, seeds, grain and occasionally small birds.
