The Jamaican Crow shares kinship with the Cuban and White-necked Crows, fellow West Indian corvids. Sooty-grey plumage blended with dark grey facial patches give the birds a distinguished look.
Sharp slate-grey beaks taper into points ideal for omnivorous appetites. Fruit, small invertebrates, even juvenile lizards all whet their palates. A sneaky snack of eggs or nestlings pilfered from other birds’ nests tops off feasts.
But amongst the laughter of its calls, an uncertain future loom. Deforestation shrinks its woodland home. As habitat withers, so too do Jamaican Crow numbers. The IUCN Red List labels them “Near Threatened”.
What other secrets do these birds hold? Let us pause and observe their mysteries before their voices fade from Jamaica’s forests.
Cuban Crow

The islands of the Caribbean are home to a sharp-looking corvid – the Cuban Crow. About 40-42 cm tall, this medium-sized bird rocks a totally unique style. It sports a long, curved bill and slick black feathers with a bluish-purple sheen in bright light. You can’t miss the patch of grey bare skin behind its reddish-brown eyes either[31] .
From Cuba to the Turks and Caicos, this adaptable bird hangs out in forests but also frequents farms and villages. It will snack on just about anything – fruits, bugs, our leftovers – you name it! The Cuban Crow has a vocal range too, making bubbling, ringing, and screeching notes.
Nesting habits are still a mystery since it hides nests high up in trees. For now, this Caribbean endemic is rated “Least Concern” by conservation groups.
With its stylish look and varied diet, the Cuban Crow continues thriving across its island range. But more study is needed to unravel the mysteries of this tropical corvid’s life in the Caribbean treetops. One thing’s for sure – it adds plenty of color, inside and out!
Sinaloa Crow Kingdom Order Family Genus Species Animalia Passeriformes Corvidae Corvus Corvus sinaloae
Along Mexico’s Pacific coastline lives the savvy Sinaloa Crow. Looks-wise, this 34-38 cm corvid is identical to its cousin the Tamaulipas Crow, both sporting slick black plumage. But don’t be fooled – the Sinaloa Crow’s jay-like voice sets it apart!
From Sonora to Manzanillo, you’ll find this opportunistic bird hanging out along riverbanks, coastlines, open woodlands, and semi-desert areas. It especially loves chilling in coastal towns and villages[32] .
The Sinaloa Crow isn’t picky when it comes to food. It uses its opportunity-seeking nature to munch on shellfish, crabs, fruits, eggs – you name it! Even other birds’ nestlings aren’t safe from this crafty corvid.
For its own nests, the Sinaloa Crow picks prickly trees or tall palms. Its nest resembles its American Crow cousin’s, just smaller.
For now, conservation groups list this Pacific coast crow as “Least Concern. ” But its impressive mimicking skills and adaptability suggest the Sinaloa Crow will continue flourishing along Mexico’s Pacific shores.
Bismarck Crow Kingdom Order Family Genus Species Animalia Passeriformes Corvidae Corvus Corvus insularis
Among the islands of Papua New Guinea lives a specialized corvid called the Bismarck Crow. This bird was originally thought to be a sub-type of the Torresian Crow but turns out to be totally unique!
Found only in the Bismarck Archipelago, the Bismarck Crow is rated “Least Concern” for now by conservation groups. But there’s still tons more to learn about this island endemic and its evolutionary story[33] .
As a genetically distinct island species, further research on the Bismarck Crow could reveal fascinating details about how it adapted to its tropical home over time. This lesser-known corvid highlights the rich biodiversity of New Guinea.
The Bismarck Crow shows that even within bird families, species can take their own separate path. More study of this island crow will help uncover mysteries about its life in the Bismarck Archipelago. For now, it remains an intriguing example of nature’s creativity when it comes to speciation.
Bougainville Crow Kingdom Order Family Genus Species Animalia Passeriformes Corvidae Corvus Corvus meeki
On the tropical island of Bougainville, one crow rules them all – the Bougainville Crow. At 41 cm tall, this heavyset bird is the only corvid in town. With its all-black plumage and massive ebony-colored bill, this crow cuts an imposing figure.
Right at home in the rainforests , the Bougainville Crow roams both the lowland forests and higher mountain forests up to 1600 meters in elevation. For now, it remains a common sight across its island range.
But logging threatens this bird’s specialized forest habitat. While still rated “Least Concern, ” if deforestation continues, the Bougainville Crow’s future could be at risk.
As Bougainville’s sole corvid, preserving its ancestral rainforests is key. With safe forests, the Bougainville Crow can continue thriving – a heavyweight forest champion in both size and spirit!
Flores Crow Kingdom Order Family Genus Species Animalia Passeriformes Corvidae Corvus Corvus florensis
On the Indonesian island of Flores lives a severely threatened bird – the Flores Crow. As a corvid found only on this one island, it has adapted uniquely to its dry and moist forest home.
But extensive habitat loss now puts the Flores Crow at risk of extinction. With its forests disappearing, this island endemic is classified as “Endangered”.
As a genetically distinct island species, the Flores Crow highlights the incredible biodiversity of Indonesia. But its uncertain future raises urgent questions. Are current conservation efforts enough? More must be done to protect this rare bird and its dwindling island forests.
The Flores Crow reminds us that localized island species play vital ecological roles. If we lose them, we lose irreplaceable pieces of nature’s intricate puzzle. With the Flores Crow’s time running out, increased habitat protections offer hope that this island corvid can bounce back from the brink.
Somali Crow Kingdom Order Family Genus Species Animalia Passeriformes Corvidae Corvus Corvus edithae
In the arid Horn of Africa lives a petite corvid called the Somali Crow. About the size of the carrion crow but with a longer bill, this bird sports slightly brownish black feathers. It was originally considered a type of brown-necked raven but turns out to be its own unique species[34] .
You’ll find the Somali Crow building bulky nests in lone trees or poles across Somalia, Djibouti, and Northern Kenya and Ethiopia. The moms lay 3-5 eggs in springtime. This bird’s harsh “caw” calls resemble its Eurasian rook cousin.
For now, the Somali Crow is rated “Least Concern” by conservation groups. But there’s still much to uncover about this slender-billed desert corvid. Further research can reveal fascinating facts about how it has adapted to the arid Horn of Africa.
The Somali Crow highlights the biodiversity of this unique region where few birds can survive. It serves as a reminder that even lesser-known species play important ecological roles.

Somewhere in the forests of Asia flies a mysterious corvid – the Eastern Jungle Crow. This little-known bird spans a wide range, inhabiting countries from China to Thailand. But details about the elusive Eastern Jungle Crow remain scarce[35] .
Its adaptability points to a varied habitat, likely including both wet and dry forests across its range. However, without dedicated research, the Eastern Jungle Crow’s specific ecology and population status stay shrouded in mystery.
This lack of knowledge is a missed opportunity to understand a unique Asian species. Targeted studies could uncover fascinating facts about how the Eastern Jungle Crow has evolved across its widespread home.
For now, the Eastern Jungle Crow remains an enigma, reminding us of the work still needed to document Asia’s rich biodiversity. By shedding light on this evasive bird, we better comprehend nature’s intricate web of life. The time has come to reveal the secrets of the Eastern Jungle Crow.
Indian Jungle Crow
Kingdom Order Family Genus Species Animalia Passeriformes Corvidae Corvus Corvus culminatus
Across India’s forests lives a slick all-black bird known as the Indian Jungle Crow. Unlike its cousin the house crow, this corvid lacks any grey neck feathers. Its rounded tail and heavy bill without a curved upper edge are other giveaways.
Once considered just a type of other crows, the Indian Jungle Crow is now recognized as its own unique species due to its distinct vocalizations and features.
This savvy bird roams the subcontinent south of the Himalayas solo, in pairs, or in small flocks. An opportunistic eater, it’ll get creative in finding food, like softening tough morsels in water.
Come breeding season, you can spot their nests built high up in large trees, containing 3-5 pale blue-green eggs. The Asian koel bird sometimes sneaks in to lay eggs of its own too!
From its adaptability to its all-black look, the Indian Jungle Crow is a true jewel that adds to India’s incredible biodiversity.
Banga Crow/Banggai Crow Kingdom Order Family Genus Species Animalia Passeriformes Corvidae Corvus Corvus unicolor
Never heard of the Banggai Crow? You’re not alone. This critically endangered bird is little known outside its remote island home in Indonesia. But the fate of the Banggai Crow highlights the wider challenges endangered species face worldwide.
These unique crows dwell solely on the Banggai Archipelago, east of Sulawesi. Discovered in 1991, only around 500 remain, mostly in the mountains of Peleng island. Their specialty? Montane forests. Yet habitat destruction threatens the Banggai Crow’s survival[36] .
Logging and potential mining have damaged the crows’ home. Though mining threats have been temporarily averted, they could return. Already the forests shrink.
And locals wrongly believe the crows steal poultry eggs, leading to persecution. With few options, the crows persist on the brink. Now, conservation efforts led by residents aim to establish protected forests where Banggai Crows can finally thrive free of threats.
But time is running short for this rare species. The Banggai Crow highlights a common plight – human activity pushing island species to extinction. Still, dedicated conservation work offers hope of averting the Banggai Crow’s demise. With quick action, this little-known bird can still have a fighting chance.
Cuban Palm Crow Kingdom Order Family Genus Species Animalia Passeriformes Corvidae Corvus Corvus palmarum
In the pine forests and around Lake Enriquillo of Cuba and the Dominican Republic dwells a small vocal corvid – the Cuban Palm Crow. Though once abundant in Cuba, this bird’s numbers have sadly dropped[37] .
Slightly smaller than its Hispaniolan relatives, the Cuban Palm Crow sports the Caribbean name “cao”, mimicking its repetitive call. Despite living alongside the white-necked crow, this bird is actually more closely related to the fish crow of the eastern US.
For now, the Cuban Palm Crow is still rated “Least Concern”. But its declining Cuban population hints that this island corvid faces growing threats.
Without more study and protection, we risk losing the distinctive voice and ecology of Cuba’s Palm Crow. Sustained efforts are needed to ensure this tropical bird continues flourishing throughout its Caribbean Island habitat.
The Cuban Palm Crow reminds us that even localized subspecies play important roles. With care, its call can continue sounding through Cuba’s forests for generations to come.
Philippine Jungle Crow Swooping through the lush forests of the Philippines is one clever corvid – the Philippine Jungle Crow. This tropical bird reaches 40-43 cm long and sports dark black plumage with subtle glossy hints of purple or blue when the light hits just right[38] .
True to its jungle crow family, this bird is a true brainiac. It can adapt to various foods and environments thanks to its omnivorous diet. Though these opportunistic behaviors may bother farmers at times, the Philippine Jungle Crow plays an important role as both predator and scavenger.
Traveling in talkative flocks, the Philippine Jungle Crow has a complex array of calls used to communicate. And with top-notch problem-solving skills, this tropical corvid can hold its own against even the most intelligent crow species.
While not currently threatened, habitat loss is a growing issue. But with conservation support, this adaptable jungle crow can continue thriving.
So next time you’re in the Philippines’ forests, listen for the calls of the Philippine Jungle Crow. It’s sure to be plotting its next clever move! This crafty bird is a reminder of the biodiversity worth protecting in these vanishing tropical forests.
Albino Crow
Although Albino Crows are not a specific species of Crows but any aforementioned crow species could get into this rare genetic condition called Albinism.
Extremely rare albino crows lack the jet black plumage that typically camouflages crows. Instead, albino crows appear snow white with bright reddish eyes. Their beaks and feet also lack melanin pigments and appear pinkish. Albino crows’ vision is impaired, and they have little chance of thriving in the wild.
Yet through random mutation, albino crows sporadically occur demonstrating that recessive albinism genes persist in crow populations at low levels. Albino crows provoke fascination and fear due to associations with supernatural spirits and mystical forces.
Former Corvus Species
The Indian roller was previously classified as Corvus benghalensis , but genetic analysis has shown it is not closely related to true crows and now places it in its own genus Coracias .
The paradise flycatcher was formerly named as Corvus paradisi by Linnaeus in 1758, but this colorful Indian bird is not a corvid and its current accepted scientific name is Terpsiphone paradisi .
The Australian magpie-lark was initially described as Corvus cyanoleucus by John Latham in 1801, but further study revealed it is not a crow and it was reclassified into the genus Grallina .
The western jackdaw and the similar daurian jackdaw were both previously considered part of the widespread Corvus monedula and Corvus dauuricus species, but they are now placed in their own genus Coloeus as Coloeus monedula and Coloeus dauuricus .
The Eurasian jay was formerly known as Corvus glandarius by Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae , but research showed it is distinct enough to be classified as a separate genus, Garrulus glandarius . In summary, while these birds were initially grouped under the Corvus genus with crows, advances in ornithology have led to reclassifications into more accurate genera based on updated genetic analysis.
Crows by Year of Taxonomy Classification From a taxonomy classification perspective, American Crow, Hooded Crow and Carrion Crow were the first set of crow species to be added to the Passeriformes order by Carl Linnaeus in 1758. The last crow species to be added was the Mexican Crow by James Lee Peters in 1929.

Frequently Asked Questions What is the difference between the American crow and raven? While they are both part of the Corvidae family, known as crows, the American Crow (Corvus Brachyrhynchos ) and the Common Raven (Corvus corax ) are different species of birds. They have a few distinct physical and behavioral differences. Ravens are larger, have a thicker beak, and a more pronounced ruffle of feathers around their throat. Ravens are also often solitary, while crows may live in larger groups or pairs.
Where can I find the habitat of the common raven? Common Ravens are widespread and can be found in a variety of habitats, ranging from forests, mountains, and grasslands to deserts and coastal lines. They can adapt to live almost everywhere except the deep interiors of large forests.
Who is part of the crow species? There are many species that are part of the crow family (Corvidae ), including not only the American Crow (Corvus Brachyrhynchos ) and the Common Raven but also many other species, such as the Hawaiian Crow, the Mariana Crow, the Northwestern Crow, and smaller species like the Jackdaw.
How to distinguish different types of crows? Different types of crows can be distinguished by their size, the shape and size of their beak, their habitat, their vocalizations, and their behavior. For example, the Northwestern Crow (Corvus Caurinus ) is slightly smaller than the American Crow and can chiefly be found in coastal regions.
What thematic behaviors have crow species been observed to do? Crows are known to be highly intelligent species of birds with observed behaviors including problem-solving and using tools. For example, a crow places pebbles into a water container to raise the water level and get to food. They also work in groups to accomplish tasks or feed effectively.
Are crows broadly mischievous in nature? Yes, due to their high IQ, crows can sometimes be characterized as mischievous. They are known to play tricks on other birds and mammals, and they have a reputation for stealing shiny objects. They are also known to gather in huge numbers in places called “crows courts” where they appear to judge the behavior of a group member.
What are the different threats to crows and ravens? Crows and Ravens face several threats, including habitat loss, hunting and poisoning, predation from larger birds like owls and hawks, and diseases like West Nile Virus. Their eggs and young are also at risk from predators, including other birds and mammals .
How do crows reach sexual maturity? Crows reach sexual maturity around two to four years of age. They tend to mate for life, and both parents help to raise their young. Mated pairs of crows will often accompany their offspring from previous years, who help raise the new chicks.
Can ravens and jackdaws communicate? Yes, like other Corvus species, Ravens and Jackdaws have complex communication systems and are believed to be able to communicate not only amongst their own species but also with other Corvus species.
Is there any unusual behavior recorded among Crows? Yes, crows have been observed engaging in what appears to be playful behavior, such as aerial acrobatics and sliding down steep snowy roofs or hillsides. Additionally, they are known to work in groups to accomplish tasks or feed effectively.
What types of habitats are suitable for different crow species? Crows are versatile creatures and can adapt to a variety of habitats. Common birds like crows are found throughout various parts of the world, including dense forests, suburbs, and even agricultural areas. They are known to roost in large flocks, mainly in tall trees made of twig nests. Hawaiian crow and the Mariana crow, for example, are found in Pacific islands. An Australian species might live in outback areas, while other species of crows are found in parts of Europe, Asia or North America.
What are the most common species of crows? While there are many different types of crow species, the most common ones include the American crow, the Hawaiian crow, and the Mariana crow. Each of these species exhibits slightly different behaviors, diets, and sounds. Some species, like the Hawaiian crow and the Mariana crow, are under the protection of the U. S. Fish and Wildlife Service due to their endangered status.
How would you describe the physical features of crows? Crows generally have strong bodies with long, sturdy legs, and wedge-shaped tails. The tail is rounded in some species. They’re often entirely black, with some species having a slight gloss to their feathers on the neck or torso. The size varies from medium to large, depending on the species.
What is the lifespan of crows in their natural habitat? While the lifespan can differ among species, most crows live for about 7-8 years in the wild. However, some crows have been known to live up to 20 years or more, particularly in areas where food supply is consistently available and there is little predation.
How does the communication system of crows work? Crows have a complex communication system including a variety of vocalizations. A common one is a long caw followed by a series of short caws, often made when a bird is separated from its mate or offspring. The meanings of these caws are still largely unknown but they rank highly on the avian IQ scale.
How would you describe the behaviour of crows? Crows exhibit a range of behaviors. They tend to be solitary or travel in large family groups. They’re known to use tools, recognize themselves in mirrors, and hold ‘funerals’ for their dead. During the late summer and fall, crows gather in large, communal roosts.
Do crows interact with humans? Yes, crows are known to live in close proximity to humans and are very adaptable. They seem to recognize individual humans and remember their faces. In urban areas, they are often seen scavenging for food while in countryside areas they may protect their territory or young from human interference.
What does a crow’s diet consist of? Crows are omnivorous which means they eat a variety of foods. Their diet includes small animals such as earthworms and small reptiles, grains, fruits, and even carrion when food gets scarce. They’re also known to eat human leftovers, making them common visitors to urban trash bins.
Can crows be considered dangerous? Generally, crows aren’t a danger to humans and tend to avoid people. However, during nesting season they can be protective of their young and may swoop if they feel threatened. Also, some people may associate crows with diseases as they consume carrions, but they pose less health risk than Pigeons or seagulls.
How to tell the difference between a crow and a vulture? While both are birds, crows and Vultures are different species with distinct characteristics. Crows are generally smaller and are covered with black feathers, while vultures are larger and often have a bald neck or torso. Crows have a wider, fan-shaped tail and a sharp, straight beak, while vultures have a long, broad wings and a hooked beak.
