About the Boat-tailed Grackle

The boat-tailed grackle (Quiscalus major) is a passerine bird of the family Icteridae found as a permanent resident on the coasts of the Southeastern and Mid-Atlantic United States. The boat-tailed grackle is found in coastal saltwater marshes and across the Florida peninsula. In salt marsh areas, least bitterns will often associate with and make mixed colonies with grackles. Boat-tailed grackles have established significant populations in several United States Gulf Coast cities and towns, using human activity as protection against predation and scavenging through human trash. Urban boat-tailed grackle populations can be found foraging in trash bins, parking lots, and outdoor restaurant patios.

The nest is a well-concealed cup in trees and shrubs near water; the average clutch size is just over three eggs. Male boat-tailed grackles compete to defend and mate with a harem of closely nesting females, although DNA evidence shows that females often successfully mate with other males while away from their colony, with only about a quarter of the young being fathered by the dominant male.

The male boat-tailed grackle is 37–43 cm (15–17 in) long... Wikipedia →
