Parakeets have ears on both sides of their head, slightly below and behind their eyes. You won’t spot them at first glance because they’re hidden beneath a layer of specialized feathers, but the ears are there: small, round openings that lead directly into the skull.
Finding the Ear Openings
If you gently part the feathers on the side of your parakeet’s head, just behind and below the eye, you’ll see a small circular opening. That’s the ear canal. There’s no outer ear flap like you’d find on a mammal. Birds never evolved external ear structures (with the partial exception of owls, whose facial discs serve a similar funneling purpose). Instead, the opening sits flush against the skin, completely concealed by feathers.
The feathers covering the ear are called auriculars, or cheek feathers. They’re not ordinary plumage. Auriculars are a complex set of feathers that channel sound into the ear while also protecting against wind and debris. The feathers directly over the ear opening have a lacy, open structure that lets sound waves pass through easily. The feathers along the rear border are shorter, sturdier, and more densely colored. Together, they work like acoustic baffles: reducing wind noise during flight and funneling specific frequencies toward the ear canal.
How a Parakeet’s Ear Works
Once sound passes through the auricular feathers and enters the ear canal, it hits a thin membrane (the eardrum), just as it does in humans. But from there, the anatomy diverges. Your ear contains three tiny bones that transmit vibrations from the eardrum to the inner ear. A parakeet has just one: a slender bone called the columella, connected to a piece of cartilage that attaches to the eardrum. This single-bone system is simpler than the mammalian version but effective enough for the frequencies parakeets need to hear.
Deeper inside, the inner ear contains a fluid-filled structure that converts vibrations into nerve signals sent to the brain. This is where hearing actually happens. Budgerigars (the most common pet parakeet species) hear across a range of about 77 Hz to 7,600 Hz, with their sharpest hearing around 3,000 Hz. For comparison, humans hear from roughly 20 Hz up to 20,000 Hz. So parakeets hear a narrower slice of the sound spectrum, missing both the very low rumbles and the high-pitched tones that humans can detect. Their peak sensitivity sits right in the range of parakeet vocalizations, which makes sense: their hearing is tuned to communicate with each other.
One interesting finding is that budgerigars, unlike pigeons and chickens, do not hear infrasound (extremely low-frequency sound below the range of human hearing). This was once assumed to be a general bird trait, but it turns out to vary significantly between species.
The Inner Ear and Flight Balance
The ear does more than process sound. The inner ear also contains the vestibular system, a set of fluid-filled canals that detect rotation and movement. This system is critical for flight. Research on birds has shown that vestibular responses increase significantly during flight compared to rest. When a bird is airborne, its head and eye stabilization responses ramp up to near-maximum sensitivity across all axes of rotation: pitch, roll, and yaw.
This means a parakeet in flight can keep its head remarkably stable even as its body twists and banks through the air. The vestibular system also triggers tail movements during flight that counteract turbulence and help maintain an upright body position. At rest, the tail stays still during the same kinds of rotational stimulation. The system essentially shifts into a higher gear the moment the bird takes off, giving it the precise spatial awareness needed for agile flight.
Checking Your Parakeet’s Ears
Because the ears are hidden, problems can develop without obvious signs. It’s worth gently parting the auricular feathers once a week to glance at the ear opening. You’re looking for redness, swelling, or any crusty discharge. Healthy ears should look clean, with smooth skin around the opening.
Behavioral signs of ear trouble are often more noticeable than visual ones. A parakeet with an ear infection may scratch repeatedly at the side of its head, rub its head against perches or cage walls, or seem generally irritated. More advanced infections can cause an unpleasant smell near the head, visible inflammation when you part the feathers, or even balance problems and vertigo. If your parakeet starts tilting its head to one side, losing coordination, or falling off its perch, the vestibular system inside the ear may be affected, and that warrants prompt attention from an avian veterinarian.
