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.

Our Nation’s forests and grasslands provide some of the most important habitats for wildlife and fish. They provide countless benefits—ecological, recreational, economic, and cultural—to both nature and society. Existing and emerging threats, such as habitat loss, climate change, and invasive species, affect the ability of our Nation's forests and grasslands to support healthy wildlife and fish populations for future generations.
Plants are also crucial to the maintenance of healthy ecosystems. Native plants provide natural beauty and help fend off invasive plants. Native plants also support wildlife, often serving as a source of food and shelter. Invasive plant species have the potential to permanently change a native plant community by taking over and outcompeting native plants.
Wildlife' includes the National Wildlife program, the National Wildlife Ecology program, and Wildlife Research & Development. The national Wildlife Program assists field biologists in attaining the Chief's wildlife priorities and manage wildlife habitat resources from a healthy ecosystem perspective.
Forest Service scientists study fish, wildlife and their habitats in order to inform land management and address existing and emerging threats, such as climate change and habitat fragmentation. Their work focuses on restoration and conservation of wildlife habitats and connectivity across large landscapes; effective management of terrestrial wildlife and their habitats under future climate scenarios; development of innovative protocols for inventory and monitoring of wildlife populations and habitats; and strategies to meet growing demands for water, energy, and other forest‐ and grassland-based commodities while ensuring the sustainability and diversity of wildlife and fish.
Between 2008 and 2015, the U.S. Forest Service and partners removed or upgraded over 1,000 culverts and road-stream crossings for Aquatic Organism Passage (AOP) across the country courtesy of the Legacy Roads & Trails Program. One of the best investments our agency can make to help aquatic ecosystems respond to the stresses of a changing climate is to restore the ability of fish to move freely, including beneath our expansive road system. Fish need to be able to access many different parts of a stream network to find cold water during the summer, to spawn, and to feed so they can grow larger. Come explore this story map to see some examples from around the country of some of the outstanding partnership projects that helped the US Forest Service achieve this milestone for fish, aquatic health, flood resiliency and protection of local transportation infrastructure.
The Flamboyant Cuttlefish resides in the tropical Indo-Pacific oceans. It favors sandy and muddy habitats at depths ranging from 10 to 282 feet.
This small sea creature displays a brown body, highlighted with white, yellow, and rich purple-pink. Due to chromatophores and pigment cells in its skin, it can alter colors. Its mantle is wide, oval-shaped, and arms have four lines of suckers.
A predator at heart, it feeds on crustaceans and fish. Meanwhile, it falls prey to seals, dolphins, and larger fish.

Marine ecologist Kerryn Parkinson found the next animal on our list of weirdest animals in 2003. The blobfish is a deep-sea animal occupying the southeastern coast of mainland Australia, Tasmania, and New Zealand waters. Blobfish won the ugliest animal online vote in 2013.
The gelatinous fish has different anatomical functions from other fish species. It lacks skeletons or muscles. The fish’s body comprises a blobby substance with a lower density than water. It helps them stay flat above the sea floor. Half its body mass contains its head, large black eyes, a huge mouth, and a bulbous nose.
Also, blobfish don’t have a swim bladder. It works to its benefit because it allows it to control buoyancy. It lives at sea depths ranging from 2000 to 3900 ft. The ocean at this depth has pressure 60 to 120 times greater than the sea surface. The lack of swim bladders prevents implosion at these depths.
With its single closed circulatory system, it can grow up to one foot long. They have a slow reproduction rate and live up to 100 years.
Next on the list of weird animals is the red-lipped batfish. The red-lipped batfish has a lipstick-red pout and frog-like legs. You can only find it on the Galapagos islands. It prefers the sandy bottom of reefs or the ocean. You’ll find the fish species at depths of 3 to 76 meters in the Pacific oceans or around the edges of reefs 120 meters deep at Galapagos islands.
It is a terrible swimmer and often uses its fins as legs to walk around the sandy bottoms of the ocean. Apart from the bright red color of its lips, the blobfish’s body color is light brown, with a gray back and white stomach.
It also has an appendage known as illicium on its head. Researchers think it uses it to lure prey in. It feeds on small fish, shrimp, and mollusks. Luckily, their conservation status is not threatened.
The next funniest animal name is, without a doubt, spot on! The fried egg jellyfish looks like a brilliantly cooked sunny-side up floating in the sea. Its tentacles form a colorful bowl-like shape.
The fried egg jellyfish is one of the few that are not harmful to humans. It feeds on zooplankton and other types of jellyfish. This type of jellyfish is also called egg yolk jellyfish since it looks more like an unbeaten raw egg floating in water than a fried egg.
The fish's face matches its funny name. Its human-like lips look like they're slathered in bright red lipstick. The rest of its body is greyish brown with a white underbelly. It has a pretty odd shape for a fish and a prominent snout at the top of its head.
Another odd thing about the red-lipped batfish is that it prefers to use its fins as pseudo-legs to walk along the seabed rather than swim. This bottom-dweller is endemic to the Galapagos Islands.
Silverfish, a nocturnal insect known for its fish-like shape, lives mostly in the dark. This insect transforms from a white hatchling to a metallic, grayish adult. Key features include two long cerci, a terminal filament, and, in a few species, small eyes.
After meat, fish is our primary source of proteins. However, is fish sustainable food? Sustainable seafood refers to seafood caught in the wild or farmed without causing a decline in marine life species. Fishes are abundant in the ocean, but the growing demand reduces their population.
The United Nations Food and Agricultural Organization estimates we overfish 85% of marine fish stocks. We move fish from their habitats before they can reproduce, reducing their population in the ecosystem. Other factors also make it difficult for fish to survive overfishing.
Things like rising sea temperatures, ocean acidification, plastic, and chemical pollution affect fish populations, making it difficult for them to survive overfishing. Overfishing disrupts the marine food web, as fish are a source of nutrients for other marine animals.
These animals would enter a state of decline because they don't feed properly. Also, the method used to fish can cause environmental damage. For instance, bottom trawling is a fishing technique that involves dragging a big net across the seabed. This method catches everything in its path.
It puts endangered animal species, i.e., sea turtles, at risk. Furthermore, the net disturbs the seabed- releasing carbon stored in the sediments. It also reduces the capacity of these areas to absorb carbon in the future.
