American Crows are approximately 16-21 inches long, showcasing an iridescent, uniform black color. These daring birds in North America adapt comfortably to open habitats, flourishing in farmlands, forests, and cities.
Their diets are notably diverse, scavenging on grains, fruits, insects, small animals, carrion, and human food waste. Scientists have also observed them modifying wood and using it to probe a small hole where a spider lives.
Regarding parenting, the Corvidae family is practicing cooperative breeding. In the 1980s, Lawrence Kilham first observed adult and yearling American Crows take turns in parenting. Young crows can stay with their parents for five years or longer1.
Moreover, the West Nile Virus has impacted their numbers by 45% since 1999. Fortunately, thanks to their resilience, they are still a species of least concern.

The Northwestern Crow stands around 17 inches tall, slightly smaller than the common crow. This type of crow nests primarily along the coasts of the northeastern Pacific Ocean, predominantly in forested areas near rivers.
Interestingly, the diet of this coastal crow differs slightly from that of its relatives. Aside from the typical crow menu, it forages along the shoreline to feed on clams, crustaceans, and sea urchins, employing different tactics to open them up.
The Hooded Crow or Scald Crow showcases a combination of grey and black body coloring. On average, this crow grows up to 20 inches in length.
It's often spotted in northern and eastern Europe and parts of the Middle East. They display a preference for woodland, farmland, and urban areas. Like the Carrion Crow, they are constantly scavenging but feed on mollusks, small mammals, nuts, etc.
The Collared Crow, distinguished by the white collar marking on its neck and chest, is significantly larger than most crow species, usually measuring up to 22 inches long.
Typically found in China and Vietnam, the Collared Crow thrives in open habitats such as fields and wetlands. Its diet mainly consists of grains, seeds, insects, mollusks, and occasionally easily accessible eggs and carrion when food is scarce.
In 2018, IUCN declared them as vulnerable species because of agricultural intensification that kills most of their prey and direct persecution by humans2.
The White-necked Crow is distinguished by its black plumage, except for a patch of white stretching from its throat to its chest. The lighter hue is hidden since it only occurs on the base of their neck feathers, which are rarely seen.
Roughly the size of a small raven, it measures about 17 to 18 inches long. It boasts a large, slightly curved bill and red iris.
This species primarily dwells in forests and woodlands across specific regions of the Caribbean, notably Haiti and the Dominican Republic. Due to agricultural conversion, hunting, and pest control, this type of crow is already extinct in Puerto Rico. Overall, White-necked Crows are considered vulnerable species by the IUCN.
The Grey Crow, also known as the Bare-faced Crow, sports a predominantly black plumage with a noticeable light grey patch at its neck and underside. It also has a bare, pinkish face and blue eyes. It measures 16-18 inches in length, similar to a medium-sized raptor.
Primarily found in New Guinea and some nearby islands, this crow species thrives in many habitats, from coastal areas to mountain forests. Their diet is varied: fruits, seeds, and small animals.
The Carrion Crow stands around 19-20 inches tall, boasting an all-black appearance that extends to their strong, stout bill and legs. Their glossy plumage exhibits hints of green and purple sheen.
You'd commonly find Carrion Crows stretching from Scandinavia to Spain across Western Europe. They adapt to numerous environments, from forests and fields to town centers.
As a predatory bird, their diet mainly comprises carrion, although they also eat insects, worms, fruits, and seeds. They also steal eggs and catch from other birds.
Fish Crows sport an all-black body, much like its relatives. It typically measures 14 to 16 inches in length. This species' distinguishing feature is its short, nasal, muffled call, different from the typical caw of other species.
These types of crows live mainly in the coastal regions and inland waters in the United States. Its diet includes fish and other seafood, hence the name, along with seeds, insects, and occasional food scraps.
The Pied Crow, standing at roughly 20 inches tall, is a native to sub-Saharan Africa. It boasts a primarily jet-black, white chest and belly area. Its habitat spans grasslands, semi-deserts, and human-inhabited areas.
This omnivorous bird has a diverse diet comprising small mammals, insects, fruits, as well as waste from human settlements.
The Cape Crow, also known as the Black Crow, showcases a glossy black body spanning up to 20 inches. It has proportionally longer body parts and slimmer bills than other crows.
Endemic to the more arid regions of eastern and southern Africa, the Cape Crow's diet mainly consists of grains, seeds, and invertebrates.
The Jamaican Crow, or the Jabbering Crow, stands out with its 15-inch size and dull black feathers. Particularly distinctive is its vocal range, with unique calls like garbled jabbering.
Thriving in Jamaica's lush forests and mountainous regions, this type of crow feeds on fruits, small reptiles, and the catch or eggs from other birds.
The House Crow stands out with its grey neck and belly, contrasting its otherwise black feathers. With a size of around 16 inches, this crow species is on the smaller side. While primarily recognized in India, it has adapted to diverse regions, including Africa, Europe, and other parts of Asia.
A true omnivore, the House Crow consumes a range of diets from plant-based materials to various types of meat, often scavenging around human population centers.
The New Caledonian Crow is mid-sized, boasting up to 16 inches long. It has iridescent black plumage and beaks with lower mandibles slightly curved upward.
This type of crow takes residence in the primary forests of New Caledonia, a group of islands in the South Pacific.
Named for their home, the Bougainville Crow inhabits the rainforests of Bougainville Island in Papua New Guinea. This moderate-sized crow comes in around 16 inches long. They don a uniform black plumage with blue gloss at the head and a purple sheen at the upperparts. Their large beaks are strongly arched downwards.
The Cuban Crow is one of the Caribbean crows alongside the White-necked Crow (Corvus leucognaphalus) and Palm Crow (Corvus palmarum). They reach sizes of up to 17 inches long. Their plumage displays a glossy, deep black hue and long, gently curved beaks.
Native to Cuba and the Isla de la Juventud, these crows inhabit both forests and agricultural lands. As omnivores, they consume a vast diet ranging from seeds and fruits to tiny insects.
The Torresian Crow, a native of Australia and Papua New Guinea, stands out due to its size. Typically measuring 19-21 inches, it is notably one of the largest species within the crow family. It boasts the standard black plumage and eyes with a white iris and blue ring.
Moreover, this bird thrives across various habitats near bodies of water, from swamps to eucalyptus woodland. They are also common in farmlands and urban landscapes.
The Tamaulipas Crow, distinctively smaller than the average crow, measures around 15 inches long. Exhibiting a glossy black body and slender bill, these crows stand out for their unique charcoal-grey eyes, deviating from the usual dark eyes of standard crows.
This type of crow inhabits the Northeastern plains of Mexico and southernmost Texas. Unlike other bird relatives, they have a low, croaking call, unlike the harsh caw that most crows are known for.
The Sinaloa crow (Corvus sinaloae) is a crow native to western Mexico.
The Sinaloa Crow, a species exclusive to Mexico's Pacific coast, is a relatively small crow, standing at a modest 14-15 inches. It's similar to the previous type of crow, but Sinaloa Crows have high-pitched calls.
The long-billed crow (Corvus validus) is a crow that is endemic to the Northern Maluku Islands. This crow is large with glossy plumage, a large bill and white irises. It is classified by the International Union for Conservation of Nature as a "near-threatened species".
The Long-billed Crow, endemic to the Maluku Islands in Indonesia, is a distinctive crow with a long beak, relatively short tail, and white iris. Akin to other crows, its plumage is black but measures up to 21 inches larger.
In 2016, IUCN reassessed these forest-dwelling birds and changed their status from "least concern" to "near threatened." The declining population results from habitat loss due to commercial logging and agricultural conversion4.
The Large-billed Crow, formerly called the Jungle Crow, is characterized chiefly by its substantial bill, with the upper part thick and arched. It showcases dark gray and glossy black plumage with a robust body measuring up to 23 inches long.
Geographically, this species is widely distributed across Asia and adaptable to forests and human-dominated landscapes.
American Crows are approximately 16-21 inches long, showcasing an iridescent, uniform black color. These daring birds in North America adapt comfortably to open habitats, flourishing in farmlands, forests, and cities.
Their diets are notably diverse, scavenging on grains, fruits, insects, small animals, carrion, and human food waste. Scientists have also observed them modifying wood and using it to probe a small hole where a spider lives.
Regarding parenting, the Corvidae family is practicing cooperative breeding. In the 1980s, Lawrence Kilham first observed adult and yearling American Crows take turns in parenting. Young crows can stay with their parents for five years or longer1.

Acronicta americana, the American dagger moth, is a moth of the family Noctuidae. It was originally described by Thaddeus William Harris in 1841 and is native to North America.
The North American Porcupine, or Canadian Porcupine, is the largest porcupine species in North America. It is distributed across various habitats and can reach three feet with tails up to a foot long.
It has around 30,000 barbed, hollow quills embedded into its skin or hair and can easily detach from the porcupine's body. Additionally, North American Porcupines feed on various vegetation, making it a nuisance to foresters. Predators like the North American golden eagles also hunt them.
One peculiar habit of the porcupine is self-anointing, which involves creating a paste and meticulously applying it to its quills. Scientists still do not know the reason behind this behavior.
The American Eel lives in the far-flung corners of the North Atlantic. It has a snakelike body and can grow up to five feet, though most individuals measure only two to three feet.
Its skin ranges from yellow to green-brown, and it has a lighter belly, camouflaging it in riverbeds and coastal waters.
These types of eels are both freshwater and saltwater eels. They spend most of their lives in freshwater or brackish environments. However, during the breeding season, they migrate to the ocean.
Additionally, these true eels eat various prey, such as insects, crustaceans, and fish. At night, the American eel emerges from the sand to hunt. They also don’t hesitate to step onto land for food.
American Crows are approximately 16-21 inches long, showcasing an iridescent, uniform black color. These daring birds in North America adapt comfortably to open habitats, flourishing in farmlands, forests, and cities.
Their diets are notably diverse, scavenging on grains, fruits, insects, small animals, carrion, and human food waste. Scientists have also observed them modifying wood and using it to probe a small hole where a spider lives.
Regarding parenting, the Corvidae family is practicing cooperative breeding. In the 1980s, Lawrence Kilham first observed adult and yearling American Crows take turns in parenting. Young crows can stay with their parents for five years or longer1.
Moreover, the West Nile Virus has impacted their numbers by 45% since 1999. Fortunately, thanks to their resilience, they are still a species of least concern.
The American crocodile reaches a hearty 13.5 feet in length, sporting broad snouts studded with sharp teeth for grappling prey.
They are the only crocodile species native to the US, primarily seen in southern Florida and at times sighted in Louisiana and Texas. Their olive-gray hue provides excellent camouflage in their surroundings, hiding them from prey until the ideal strike moment.
Because of their adaptability, these crocs are the most widespread of all species living in America. They can survive in fresh wetlands, coastal lagoons, and river estuaries and even handle saltwater, courtesy of special glands that filter out excess salt. Other types of crocodiles may have tolerance to salt. Still, only the American crocodile4, other than Saltwater Crocodiles, can thrive in saltwater environments.
Despite their formidable presence and efficient predation, they tend to be reserved and mainly avoid humans. Males are territorial, and despite their solitary life, they contribute significantly to the ecosystem by keeping prey populations in check.
The South American Rattlesnake, also called Tropical Rattlesnake, presents a mix of tans and browns, beautifully designed with diamond-shaped markings along its back. Averaging between 4 and 5 feet, it sports longitudinal rows of keeled scales, lending to its rugged surface texture.
Naturally occupying a broad range of habitats, it is typically found in forests, grasslands, and deserts across South America. This species is active the most during the early morning and dusk. Its diet primarily consists of small mammals, but it also preys on lizards in other areas.
The American Red Squirrel is a small, active rodent in North America's coniferous forests. Their fur is reddish and can range from a soft rusty red to a deep chestnut brown.
They are most active during the early morning and late afternoon, searching for food or guarding their territory.
Likewise, they eat coniferous tree seeds, mushrooms, fruits, and berries, and sometimes even bird eggs or young birds.
They observe "larder hoarding" to store food in a central cache for the winter months, showcasing their industrious nature.
The North American River Otter can survive in various habitats ranging from the icy rivers of Alaska to the humid marshlands of Florida.
These mustelids have a streamlined body, weighing 25 pounds and standing up to 3.5 feet. They also have a broad, flattened head and thick fur, insulating them against the cold of their watery habitats.
These otters have a varied diet, with fish being their main staple. In addition to fish, they also eat amphibians, crustaceans, small mammals, and birds.
Interestingly, North American River Otters perform a poop dance and use designated "latrine sites" for their waste deposits.
