The Common Grackle can be a handsome bird when seen from a short distance. Covering its head, neck and upper breast is a purple iridescence that can amaze viewers in the right light. The rest of its feathers, including its long, wedge-shaped tail, are glossed in a bronze-green sheen. But this beauty can be lost on many; a result of the combination of the grackle’s lack of table manners (and all other manners), its voice that sounds like “an un-oiled wheelbarrow” and the invasion of both lawn and feeders by large flocks of these noisy birds.
Canada’s largest blackbird is both noisy and cocky, and is a resourceful forager. The grackle’s main summer diet consists of insects, small invertebrates and occasionally the eggs and nestlings of other birds. In winter, it will eat waste, grains, seeds, fruit and garbage. They will follow plows to catch invertebrates, pick leeches off the legs of turtles and steal worms from robins, among other techniques to get fast food. The grackle breeds in many different sites but it favours damp, open woodlands, the shores of lakes and streams and wet meadows. Be on the lookout for Grackles as they return to Alberta in April; they are almost here.
The young grackle is even noisier than the adult.
Note the long, wedge-shaped and keeled tail of this grackle.
