Why Do Lions Roar? Reasons Behind Iconic Sound

Are you ready to take a walk on the wild side and learn about one of the most fascinating sounds in the animal kingdom? We’re talking about the mighty roar of lions, the kings and queens of Africa. 

You’ve heard it before, right? That deep, rumbling growl that sends shivers down your spine and makes you feel like you are standing in the presence of royalty. 

But have you ever wondered why lions roar? Is it a way of saying, “hey, I’m over here!” or does it serve a deeper purpose? 

Fear not, my curious compadres, because in this blog post, we are going to dive deep into the roaring world of lions and uncover the significance behind these magnificent vocalizations.

Why Do Lions Roar?

Both male and female lions roar for several reasons: communication with other members of their pride, displaying their health and strength to potential rivals, marking their territory to deter intruders, and attracting mates. The roar can be heard up to 5 miles away, making it an effective way for lions to communicate and establish their dominance in their environment.

Key Points:

  • A roar is an important form of lion communication.
  • Not all roars are the same, but they all are a key part of lions’ social life.
  • Each lion has a unique roar.
  • A lion roar is measured at 114 Db
  • Lions typically roar at night or in the early morning.


Most members of the cat family live solitary lives. They would stay with their siblings until becoming sexually mature, and at that point, they would separate from the group and continue on their own.

Lions are an exception to this. These big cats are some of the most social wild animals that live in groups with a strict hierarchy.

Roaring is a vital part of lions’ interaction with each other and other animals. They use different types of roars to communicate different things.

But, did you know that each lion has its unique roar? In fact, a team of researchers from Oxford University recently made this incredible discovery.

By learning the variations in roar frequencies among pride members, lions can identify familiar roars.

So, for example, if some pride members become separated from the group, lions can use this ability to distinguish their friends from their foes and reunite with the rest of the pride.

This remarkable ability highlights just show how complex lion communication truly is.

Besides roars, lions also produce different vocalizations to communicate with their pride members, including grunts, growls, snarls, and moans.

And in addition to their vocal means of communication, lions also use nonverbal ways to communicate with one another.  A handshake in a lion’s world consists of rubbing heads, licking, and looping their tails with each other.

Territorial Display

Territorial display is an important behavior for many animals, including lions. It serves as a way for them to establish and defend their territory from other predators. 

For lions, this involves roaring, marking with urine, and rubbing on trees, among other methods.

Roaring is one of the most distinct and effective ways for lions to assert their dominance and claim their territory. 

A lion’s roar can be heard up to 5 miles across African savannahs, and it sends a clear message to other lions about territorial boundaries. The greater the number of roars, the more powerful and dominant the pride is perceived to be.

Attraction of Mates

Lions use different strategies to attract mates, and one common way is using roaring sounds. 

When female lions are in heat and ready to mate, they communicate this with males by scent, body language, and calling. 

In response, male lions produce a deep, resonant roar that demonstrates their health and masculinity to potential mates. Lionesses are attracted to strong and dominant males, making the roar an important part of their mating ritual. 

Displaying Health and Strength

Lastly, lions often use fierce roars as a way to gauge strength. A loud and powerful roar is a clear sign that a  lion is in good condition and ready to defend its territory and pride. 

However, a lion’s roar isn’t their only tool to show off dominance.

The length and color of a lion’s mane can tell us a lot about a lion’s health and physicality.

Typically, longer and darker manes are associated with older, more dominant lions. This is due to the fact that a lion’s mane grows and darkens with age, making it a good indicator of one’s combat experience.

Frequently Asked Questions About Lion Roars

In this section, we’ll address common questions and facts about lion roars.

Why Do Lions Roar at Night?

Lions are known to be nocturnal animals, and they roar at night because they are primarily active when the sun goes down. During the day, lions usually rest and conserve their energy, hence they are more often heard at night.

Why Do Lions Roar in the Morning?

Lions roar in the morning because, under specific conditions, their mighty vocalizations travel even further. Lions tend to roar more when the wind is calm, the temperature is cooler, and the air humidity is higher, which is usually around dawn.

Why Do Lions Roar in the Zoo?

Lions tend to roar less frequently in the zoo than in the wild, which is not surprising since they typically use their roar to warn off trespassers in their territory. In captivity, lions don’t encounter other lions or prides, so they don’t need to send this warning.

However, roaring is not solely a warning sign, which is why lions may still occasionally let out a roar in the zoo.

Do Lions Roar When Hunting?

No, lions don’t roar when hunting. When hunting, lions usually act stealthily and silently in order to avoid alerting their prey. Roaring before attacking would be counter-productive to their style of hunting.

Do Lions Roar After a Kill?

After securing a kill, lions usually don’t roar. There is an eating hierarchy among lions, so they might snarl or growl to communicate with their pride members and to signal that they are willing to share prey, but they don’t roar to mark a victorious hunt.

How Loud Can a Lion Roar?

At one meter distance, a lion’s roar can reach up to 114 decibels. This is louder than a music concert (110db) and almost as loud as a jet plane at take-off (120db).

Lion’s roar is so loud because of the anatomy of their vocal cords. Unlike other animals, their vocal cords are not triangle-shaped; instead, they are flatter and shaped like a square, allowing them to produce such monstrous roars.

Do Lions Roar Louder Than Tigers?

Lions have louder roars than tigers. Tiger roars are also pretty powerful, traveling 2 miles away, but lions have the loudest roars of all big cats.

Final Thoughts

Roaring is a critical adaptation for lions, as it serves as a vital component of their communication with their pride and plays a significant role in their mating rituals and territorial displays. 

Unsurprisingly, a lion’s roar is one of the most recognizable sounds in the animal kingdom. It can carry over a distance of up to 5 miles and hit a volume of 114 decibels, making it an awe-inspiring experience to witness in person.
