Ravens and crows, both members of the Corvus genus, are often confused for one another. While they share some similarities, there are key differences, one of the most noticeable being size. This article will explore the size difference between ravens and crows, along with other distinguishing features.
Size Differences: Raven vs. Crow
Ravens are significantly larger than crows. A raven can measure up to 26 inches (67 cm) in length with a wingspan reaching 51 inches (130 cm). In contrast, crows average around 18 inches (46 cm) long with a wingspan of approximately 36 inches (95 cm).
Think of it this way: a raven is roughly the size of a Red-tailed Hawk, while a crow is closer in size to a pigeon. However, judging size solely by observation can be tricky unless both birds are the same distance away.
Other Distinguishing Characteristics
Beyond size, there are other ways to tell ravens and crows apart:
Tail Shape in Flight
Observe the tail shape when the bird is in flight. A raven’s tail feathers form a distinct diamond shape, while a crow’s tail is more of a fan with a straight edge.
Beak and Throat Feathers
Ravens have a much larger, more robust beak than crows. Additionally, ravens possess shaggy throat feathers, resembling a thick beard or ruffled cravat. Crows have smoother throat feathers.
Flight Patterns
Ravens are known for their soaring flight, effortlessly gliding on air currents. Crows tend to flap their wings more frequently and have a less graceful flight pattern. While crows can also soar, they primarily rely on flapping for locomotion.
Vocalizations
The calls of ravens and crows are distinctly different. Crows have a familiar “caw” sound, while ravens produce a deeper, croaking sound, often described as a “quork” or a low, guttural croak.
Behavior
Crows are often seen mobbing ravens, chasing and harassing them. This is usually due to ravens’ tendency to raid crow nests for eggs.
Conclusion
While both birds are black and intelligent, understanding the size difference between a raven and a crow, along with other distinguishing characteristics like tail shape, beak structure, throat feathers, flight patterns, and vocalizations, can help you differentiate between these fascinating corvids. Ravens are notably larger, with a more robust build and distinctive features that set them apart from their smaller crow relatives.
