Common grackle 普通拟八哥 （北美雀鸟)
The common grackle, also known as the North American grackle, is a medium-sized bird found throughout North America. These birds belong to the family Icteridae, which also includes blackbirds, orioles, and meadowlarks.
Measuring approximately 12 inches in length with a wingspan of around 18 inches, common grackles display sexual dimorphism in their plumage. Males boast glossy black feathers with an iridescent purple and blue sheen, while females are a duller black-brown color. During the breeding season, males engage in elaborate courtship displays to attract females, puffing out their feathers, spreading their wings, and producing a variety of calls and songs. Females construct nests in trees, shrubs, or other vegetation, typically laying 3 to 7 eggs per clutch. Both parents participate in incubating the eggs and caring for the young.
These birds are highly adaptable and thrive in a range of habitats, including forests, grasslands, wetlands, and urban areas. As omnivores, common grackles have a diverse diet that includes insects, small mammals, seeds, fruits, and even garbage. While they are often considered pests due to their tendency to raid crops and steal food, they also play a crucial ecological role as seed dispersers and insect predators.
