With their bright plumage, snoods, and wobbly gobbles, wild turkeys are a distinctive bird. But if you look at a turkey’s head, you won’t see any external ears like those found on most mammals. So do turkeys have ears at all? The answer is yes – but they are not as prominent as a human or dog’s. Understanding how turkeys hear helps illuminate their keen senses that aid survival.
The External Ear of a Turkey
The most obvious difference between a turkey’s ears and a human’s is the lack of an external structure The flap of cartilage and skin known as the pinna is absent in turkeys The pinna performs an important function in mammals by collecting sound waves and funneling them into the ear canal.
Turkeys lack these prominent outer ears, instead having just a small opening on each side of the head But while less conspicuous, these openings still allow sound to enter the inner ear effectively. The external ear of a turkey is simply structured differently than a human or dog’s external ear
The Inner Ear Structure
Internally, a turkey’s ear contains the same basic parts as a human ear – the outer, middle, and inner ear. Sound enters through the external opening into the middle ear, which contains bones called ossicles that transmit sounds to the inner ear.
The inner ear houses the cochlea, which converts sound waves into nerve signals sent to the brain. While shaped differently, these inner ear components serve the same hearing functions in both humans and turkeys.
Excellent Hearing Abilities
Despite the lack of prominent outer ears, wild turkeys have exemplary hearing. Their sense of hearing is very acute, allowing them to perceive a wide range of frequencies and identify the source of faint sounds. Turkeys rely on their hearing to help avoid predators and communicate.
Some key facts about a turkey’s hearing include:
-
Can localize sound direction accurately, even pinpointing subtle calls from hundreds of yards away.
-
Sensitive to a broad range of frequencies, both low and high-pitched.
-
Hear higher frequency sounds better than humans.
-
Ears can operate independently, giving turkeys expansive 360-degree hearing.
-
Hearing remains acute even when vision is obstructed.
So while they don’t have conspicuous external ears, turkeys hear exceptionally well in their forest environments. Their hearing augments their keen vision to create alertness to predators.
Turkey Hearing vs. Human Hearing
There are some notable differences between human and turkey hearing capabilities:
-
Detection range – Turkeys can hear sounds from farther away than humans can, picking up faint calls hundreds of yards off.
-
Localization – Turkeys excel at pinpointing the exact location of sounds, while humans tend to be less precise.
-
Frequency range – Turkeys hear a wider range of high frequencies compared to humans.
-
Independence – Turkey ears operate separately, allowing 360-degree coverage versus a human’s overlapped coverage.
So while turkey ears may be less prominent, their hearing abilities actually surpass those of humans in some regards. Our species relies more heavily on vision as our primary sense.
Roles of Hearing for Wild Turkeys
For wild turkeys, exceptional hearing serves several crucial purposes:
-
Predator detection – Turkey hearing allows early warning of approaching predators like coyotes, foxes, and bobcats even if obstructed from view.
-
Communication – Turkeys use vocalizations extensively to communicate with flock members, locate other turkeys, and signal danger. Their hearing picks up these vocal cues.
-
Reproduction – Male turkeys rely on hearing to detect female calls and follow them to find breeding opportunities.
-
Navigation – Turkeys use hearing to discern features in their habitat and avoid obstacles while moving through vegetation.
Their specialized ears allow turkeys to thrive in the forest environments they inhabit. Hearing works seamlessly with their other keen senses.
Turkey Hearing Loss
Like humans, turkeys can experience hearing impairment as they age or due to injuries and illnesses. Some signs a turkey may have diminished hearing include:
-
Lack of response to noises or calls
-
Failure to detect predators
-
Becoming more solitary and less communicative
-
Increased startle responses if approached unheard
-
Delayed reactions to vocalizations from other flock members
Hearing loss puts wild turkeys at a survival disadvantage. They become more vulnerable to threats that they cannot hear approaching. But turkeys with mild to moderate hearing issues can still adapt and live successfully in the wild.
Fascinating Hearing Abilities
While turkeys lack external ears, they benefit from astute inner ear structures fine-tuned by evolution. A turkey’s hearing capabilities are fascinating and far surpass our own in some ways. Next time you see a wild turkey, consider its ears hidden from view that allow it to expertly interpret the forest soundscape. Thanks to superb hearing, turkeys remain vigilant and always on alert.

FAQ
What do turkey ears look like?
How good can turkey hear?
Do turkeys have external ears?
Do turkeys have bad hearing?
Do turkeys have ears?
“The ears are behind and slightly below their eyes,” Chamberlain said. “Turkeys have no external ear like we do, but their ears register volume of sounds separately and transmit that information to the brain. That allows turkeys the uncanny ability to determine distance to a sound and then go to that exact spot where they heard the sound.”
Do wild turkeys hear a lot?
Dickson’s compilation of wild turkey experts reveals that a wild turkey’s hearing is acute, although its external ear lacks a flap, or pinna, which concentrates sound waves. Field observations suggests turkeys hear lower-frequency and more distant sounds than humans. “Touch comes into play primarily for feeding,” Eriksen said.
Do turkeys have ear lobes?
What that means is that they probably can hear tones that are too low or high for us to hear. Unlike us humans, turkeys do not have ear lobes (called pinnae) to gather in the sounds. The purpose of an earlobe is to help gather the sound in so it is easier to hear. If you have a dog, watch them as they adjust their ears to hear sounds.
Do turkeys have good eyesight?
Not only do turkeys have incredible eyesight, their hearing is also very good too. A wild turkey can hear sounds clearly in the forest from far away, especially in the night. This helps them to stay alert at all times and keeps them protected from predators.
