American Crow vs Common Raven: A Guide to Identification and Behavior

American Crows and Common Ravens are two of the most intelligent and fascinating birds in North America. They're often confused with each other due to their similar appearances.

One way to tell them apart is by their size, with Common Ravens being larger and heavier. In fact, Ravens are about 23-27 inches long, while Crows are about 20-24 inches long.

Both birds are known for their distinctive calls, but Ravens have a deeper, more raspy sound, often described as a low, guttural croak. Crows, on the other hand, have a higher-pitched, more nasal call.

American Crows are smaller and slimmer overall than Ravens, with smaller bills and thinner legs. Crows have shorter, rounder wings and shorter squarish tails, which fan out when spread.

In flight, Ravens have longer, more swept-back "hands" and longer, wedge-shaped tails. Their wings are longer than those of Crows, and their tails are often rounded or wedge-shaped.

To tell them apart, listen to their calls: Crows make a "caw-caw" sound, while Ravens croak. If you see them vocalizing, Ravens show a shaggy beard on their throat and neck, while Crows have a smooth throat and neck.

Ravens are larger than crows, with larger, thicker bills, stronger legs, longer, wedge-shaped tails, and more tapered, longer wingtips.

One of the most noticeable differences between ravens and crows is their size, and it's not hard to tell them apart when you see them side by side. Ravens are often seen in pairs, and sometimes in large flocks (100+), but rarely occur in flocks of thousands like crows.

Crows, on the other hand, are smaller and slimmer overall than ravens, with smaller bills and thinner legs. They're also more likely to be seen in huge flocks, sometimes numbering in the thousands.

In flight, ravens are more raptor-like, soaring for extended periods, unlike crows. Ravens have deeper, hoarser voices, and their characteristic call is a deep 'rok!' or 'rok-rok-rok!'.

Crows have shorter, rounder wings than ravens, and shorter squarish tails; fan-shaped when spread. Their calls are higher-pitched and more nasal than ravens.

Generally, the vocalizations of American Crows and Common Ravens are quite distinct. They can be traced to a croaking pattern in Ravens and a caw-caw pattern in Crows.

One way to tell them apart is by looking at their beards while they vocalize. Ravens show a shaggy yet ornate beard, while Crows maintain a mostly smooth throat and neck.

In fact, Common Ravens are known to croak, and when calling, they show and expand a shaggy beard on the throat and neck. American Crows, on the other hand, caw-caw and purr.

Here's a quick summary of the vocalizations and beards of these two birds:

American crows are significantly smaller than ravens, weighing less than a pound and measuring 17 to 21 inches from beak to tail. They have a wingspan of 34 to 39 inches.

The common raven is as big as a hawk, reaching 21 to 27 inches in body length and sporting a wingspan of 46 inches. They weigh 1.5 to nearly 4 pounds, making them the largest songbird in North America.

If you're trying to identify the birds, check the bill - the common raven's bill is longer, wider, and has more of a hook at the tip than the American crow's. The common raven's throat feathers are often shaggy, giving them a "full" throat and a large-headed appearance.

When identifying ravens and crows, one of the most noticeable differences is the size of the birds. Ravens are about 30% larger than crows, making them a good deal bigger.

To put that in perspective, ravens are roughly the same size as a Red-tailed Hawk, measuring 24 inches in length, 2.6 pounds in weight, and 53 inches in wingspan.

One way to tell the two birds apart is by looking at their beaks. Ravens have a heavier, longer, and curvier beak, while crows have a thinner and more straight beak.

Ravens also have thicker, longer, and more developed bristles on their beaks, which can be a good indicator of their identity.

Here's a quick comparison of the physical characteristics of ravens and crows:

By paying attention to these physical differences, you can get a better sense of whether you're looking at a raven or a crow.

The bill of a raven is described as "Roman" due to its prominent bridge and sloping profile.

A raven's bill is quite a bit larger than a crow's, making it a distinctive feature.

Ravens' bills are often referred to as "Roman" because of their resemblance to a human "Roman" or aquiline nose.

When identifying ravens and crows in flight, a key difference is their tail shapes. Ravens have tail feathers that are longer in the center, forming a wedge or diamond shape. This is in contrast to crows, which have tail feathers of the same length that spread out like a fan.

If you're trying to tell these birds apart, look for the distinctive shape of their tails. Ravens have a pointed or rounded tail shape, while crows have a short, square tail.

In flight, the tail feathers of ravens and crows can be a great clue for identification. Ravens have a more complex tail shape, while crows have a simpler, more rectangular shape.

Here are the key differences in tail shape to look for:

By paying attention to these subtle differences, you can improve your chances of correctly identifying ravens and crows in flight.

Identifying American Crows and Common Ravens can be a challenge, but there are some key differences to look out for.

Common Ravens often spend their flight time doing aerobatics and almost 'playing'.

If you're still unsure, take a closer look at the bird's size - Common Ravens are larger than American Crows.

Common Ravens are also known for their more raucous, deeper calls, often described as a low, guttural "croak".

In most of the U.S., the common raven's range does not overlap with that of the American crow. However, in the Appalachian Mountains of the eastern US and the northern portions of several states, both species can be found in the same region.

The common raven and American crow widely overlap in most of Canada and the Western US. This means that in these areas, it's not uncommon to see both species together.

In the western region of the US, common ravens use a wide variety of habitat types, from forests to grasslands and agricultural areas. In contrast, American crows are highly adaptable and can be found in almost any habitat type.

In the Eastern US, common ravens are more restricted to forests, mountains, and most wild places. American crows, on the other hand, generally avoid pristine forests and wild places, but may be present in human-created openings such as farms and recreation areas.

Here's a summary of the differences in habitat use between ravens and crows:

If you see a solo or a pair of black Corvids in the mountains, it's likely ravens. A flock of corvids is likely to be composed of American crows.

Ravens simply fold their wings upon landing, whereas crows "shake" or "re-arrange" their wings and quickly "flick" their tail.

Ravens walk, and when they need to walk faster, they hop with their two legs together. Crows, on the other hand, walk even when they want to walk faster.

These unique behaviors can be quite conclusive, and by observing them, you can tell ravens and crows apart.

Here's a quick comparison of their landing and walking behaviors:

These differences in behavior can help you tell ravens and crows apart, even in areas where they don't overlap.

When trying to identify these birds, it's essential to pay attention to their sounds. Crows make a harsh, raspy noise, while ravens produce a gurgly, croaky sound.

If you're still unsure, take a closer look at their wingspans. Crows typically have a wingspan of up to 39 inches, while ravens can stretch up to 46 inches.

A glance at their tails can also be telling. Crows have fan-shaped tails, while ravens have wedge-shaped tails.

Crows and ravens have distinct vocalizations. Their calls are one of the easiest ways to tell them apart.

A crow's typical call is a raspy "Caw! caw! caw!" sound, often used as a territorial call. They also make a rattle sound that's similar to cackling.

Ravens, on the other hand, have a more gurgly and croaky sound. They're known to "talk" on their own, with others, or in response to another raven's call.

Crows can mimic human speech, and semi-captive crows have been known to learn and repeat words and phrases. This is just one of the many fascinating vocalizations these birds are capable of.

Ravens, however, are more likely to imitate other birds and sounds they hear in their environment. Scientists have documented 33 types of common raven vocalizations, including predatory alarms and comfort sounds.
