The big black bird that you often see in northern Illinois is most likely the Common Grackle. These birds are known for their striking black plumage and their resourcefulness in finding food. As an expert in bird species, I can confidently say that the Common Grackle is a common sight in this region.
One of the defining characteristics of the Common Grackle is its size. These birds are larger than many other blackbirds, measuring about 12 inches in length. Their long tails and slender bodies give them a sleek appearance as they fly through the air.
When it comes to their preferred habitat, Common Grackles are adaptable and can be found in a variety of environments. They are often spotted in open areas such as fields, meadows, and even urban parks. In fact, they are known to thrive in human-altered landscapes, which explains their presence in northern Illinois.
One of the reasons why Common Grackles are so successful is their ability to find and exploit food sources. Their diet primarily consists of grains, such as corn and rice. They are particularly fond of cornfields and will gather in enormous flocks to feed on the crop. It is not uncommon to see hundreds or even thousands of Common Grackles gathered together in a single field.
Their resourcefulness doesn’t end with grains, though. Common Grackles are also known to eat insects, fruits, and even small vertebrates. This versatility in their diet allows them to adapt to different seasons and environments, ensuring their survival and abundance.
I have personally observed the behavior of Common Grackles in farm fields in northern Illinois. It is truly a sight to behold when a massive flock of these birds descends upon a field, their iridescent feathers shimmering in the sunlight. They move together in a synchronized manner, hopping and pecking at the ground to uncover their desired food.
In addition to their feeding habits, Common Grackles are known for their distinctive vocalizations. Their calls are often described as harsh and grating, which can be heard from a distance. These vocalizations serve various purposes, including communication within the flock and establishing territory.
The Common Grackle is a fascinating bird species that has adapted well to its surroundings in northern Illinois. Their ability to find food, their adaptability to different habitats, and their impressive flocking behavior make them a common and iconic sight in the region. Keep an eye out for these resourceful birds the next time you are in an open field or park in northern Illinois.
