The Truth About Crows and Their Eating Habits


Crows are an intriguing species of bird that can be found all over the world, either alone or in groups referred to as murder. While some people view them as a symbol of death and misfortune, others see crows as a sign of the cycle of life. These birds are often known for their scavenging behavior, feeding on carrion left behind by other animals. 

That’s right, crows and other species of scavenger birds are an essential part of the ecosystem, providing a vital service by cleaning up animal remains. This article aims to explore the diet and behavior of crows as carrion birds, shedding light on their fascinating role in the natural world.

What Does Carrion Mean?

Carrion, the decaying flesh of a dead body as food for scavenging animals, is an essential food source for certain species of birds. Known as carrion birds, vultures, and condors are perhaps the most famous of these scavengers. However, depending on the size of the carcass and how much activity is around it, other omnivorous birds such as jays, pigeons, roadrunners, and hoopoes may also take advantage of carrion. 

Even some seabirds, including fulmars, have been known to scavenge carrion from beached carcasses. It’s important to note that not all dead animal bodies are considered carrion. A dead animal killed and eaten by the same animal is not considered carrion; it must have died from another cause. Hence, bodies of animals that died from natural causes and are left to decay, can serve as a vital resource and contribute to sustaining different animal populations in nature.

 To be categorized as carrion, the remains of animals must have perished in a subsequent manner:

  • Animals killed by other predators
  • Hunted animals discarded by hunters
  • Roadkills of animals killed by vehicles
  • Animals that died from accidents
  • Animals that died naturally
  • Stranded animals

Crows and Their Eating Habits: Why Do Crows Eat Dead Animals?

Carrion consumption diverges from typical human and animal norms. Crows possess a distinct digestive system with greater resilience to decomposed meat. Generally, the crow finds older carcasses more delectable, as aging meat becomes more tender and easier to consume. Although deceased animals serve as a natural food source for carrion birds like crows, they also bring forth potential hazards, including:

  • Disease propagation is due to an abundance of bacteria.
  • Contamination from previous carrion consumers.
  • Poison exposure particularly leads, if the animal was hunted.
  • Pesticide taint.
  • Vulnerability to attacks by other predators attracted by the scent of the expired animal.
  • Possibility of collisions with vehicles while feeding on roadways.

Crows, akin to their carrion counterparts, have evolved to contend with these perils. Their potent stomach acids act as a defense against numerous disease-causing bacteria. Unfortunately, crows and other carrion birds lack the ability to detect lead and other toxins within a deceased creature. Therefore, hunters are encouraged to switch to non-lead ammunition to mitigate these risks.

Why does a crow eat roadkills?

Crows are not considered birds of prey, but did you know that they can thrive on a diet of meat? The digestive system of these black-feathered birds is so efficient that they can absorb nearly everything, including roadkill and worn-out meat from dead animals. While older meat is considered tastier and more tender for crows, its gastrointestinal system is also durable enough to reduce possible contamination and poisoning. 

Crows will rarely kill for meat, preferring instead to scavenge for it. They like other animals to do the hunting, leaving the prey for themselves to eat. So the next time you see a crow nibbling on some fresh roadkill, remember that it’s not just a scavenger, but a skilled opportunist using its highly adapted digestive system to turn what others might consider unappetizing into a valuable source of protein.

Crows and Their Eating Habits: Digestive System Of Crows

Crows lack the ability to chew their food. Instead, the ingested food travels down the esophagus and enters the crop—a storage organ. From there, the food is gradually released into the proventriculus.

Within the proventriculus, chemical digestion takes place thanks to the action of gastric acid and enzymes. Subsequently, the food progresses to the gizzard. Crows have the tendency to ingest stones, which then reside in the gizzard. These stones aid in the breakdown of food into more manageable fragments.

Following its passage through the gizzard, the small intestine comes into play, absorbing essential nutrients. Subsequently, the large intestine and the ceca play their role in absorbing electrolytes and water. What remains is excreted as feces and is expelled into the cloaca. The cloaca serves as the shared opening for the digestive, urinary, and reproductive systems.

Crows and Their Eating Habits: Do Dead Bodies Attract Crows?

Deceased bodies have a magnetic pull on crows, as well as other carrion birds. Crows possess the ability to detect carrion either through its scent or by sight. Unlike their avian counterparts, crows exhibit intelligence and highly communicative nature, looking out for one another.

Mature crows are notably resilient to threats. They gather around deceased animals primarily for the purpose of feeding. However, their behavior takes a distinct turn when a fellow crow meets its demise. During such occasions, the assembly of crows serves a different purpose – a sort of crow funeral. This gathering serves as a method for them to grasp the perils of their environment.

By observing the circumstances of the deceased crow, they learn valuable lessons about potential dangers. This information-sharing session is integral to their survival strategy. Crows have the capacity to analyze the cause of death, using the insights gained to thwart future threats from predators.

Crows and Their Eating Habits: Will Crows Consume A Dead Bird?

Crows serve as nature’s scavengers, capable of feeding on nearly any deceased animal or bird. When they come across a deceased bird, they readily consume it.

 Crows and Their Eating Habits: Do Crows Consume Their Dead?

Indeed, crows have been observed consuming their own deceased members. They tend to operate in familial groups and occasionally engage in conflicts, both within their own household and beyond.

Internal disputes within a crow family are infrequent occurrences. External conflicts typically arise with the purpose of safeguarding essential resources like food, fellow crows, or the territorial boundaries of their habitat.


Will crows eat a dead body?

Yes, crows are known to consume dead bodies, including those of other animals. They are opportunistic scavengers and have a diet that includes carrion, which refers to the flesh of dead animals. Crows have a remarkable ability to detect and locate carcasses, whether through their keen eyesight, sense of smell, or other cues. 

Will crows eat rotten meat?

Yes, crows are known to consume rotten or decomposed meat. They have a high tolerance for eating carrion that is in various stages of decay. Their digestive systems are adapted to handle bacteria and other potential contaminants that may be present in decomposing flesh. 

Which bird eats the remains of dead animals?

Carrion birds, such as vultures, ravens, crows, eagles, and magpies, are dedicated scavengers that play a crucial ecological role by consuming the remains of dead animals. These birds are equipped with adaptations that allow them to feed on decaying flesh, aiding in the cleanup of the environment. Vultures, for instance, possess keen eyesight and potent stomach acids to digest pathogens. 

Ravens and crows exhibit intelligence and opportunistic behavior in scavenging. Eagles, particularly some species, and storks like the marabou stork are also part of the carrion-eating group. By recycling nutrients and helping prevent disease spread, these birds contribute to the balance of ecosystems.

Final Words

Crows, classified as carrion birds, exhibit scavenging behavior by consuming deceased animals. Carrion, which refers to the decomposed flesh of dead creatures, serves as a significant food source for crows and similar scavenger birds. Crows are drawn to and feed on dead animals either individually, in pairs, or in groups.

When crows congregate around a deceased animal, it’s primarily for sustenance. However, if a fellow crow meets its demise, the gathering takes on a different purpose – the quest to ascertain the cause of death and to warn other crows. Unlike humans, crows and fellow carrion birds possess a robust digestive system that can withstand potential poisoning and contamination, enabling them to ingest dead animals with lower risks.

Crows exhibit remarkable cognitive abilities; they can recognize faces, particularly those representing threats. This, coupled with their alertness, allows them to safeguard themselves by warning other crows. In addition to crows, other bird species also incorporate deceased animals into their diets.
