Penguins' hearing seems much more basic, as they can only hear 100Hz to 15 000Hz, and their small heads and flat ears limit their ability to detect the direction of sound.

How do penguins hear without ears?
Hearing Without Ears
There are no external flaps, just holes on either side of the head covered by feathers. While these “listeners” don't look like ours, they are great for hearing. Penguins can easily identify a particular mating call among the squawking of other birds.
Do penguins see in color?
But water's density prevents our eyes from seeing anything well even at a distance. ... When Martin tested penguins' color vision, he discovered that they do not see red. They do see violet, blue and green. Even though they spend much of their life on land, their eyes are adapted to the underwater world, where they hunt.
What does a penguin ear look like?
When you look at a penguin's head you can see their eyes, their beak, even a tongue if they open up. But you will not see any ears. ... Their ears are just holes and are covered by feathers. The absence of external ear flaps gives the penguins a more streamline shape and minimizes drag as they swim through the water.
What do penguins communicate?
Penguins communicate by vocalizing and performing physical behaviors called displays. They use many vocal and visual displays to communicate nesting territories, mating information, nest relief rituals, partner and chick recognition, and defense against intruders.
Can penguins fly?
No, technically penguins cannot fly.
Penguins are birds, so they do have wings. However, the wing structures of penguins are evolved for swimming, rather than flying in the traditional sense. Penguins swim underwater at speeds of up to 15 to 25 miles per hour .
Do penguins have teeth?
Of course penguins do not have teeth, but it sure looks like their tongue and the roof of their mouth does! Those teeth-looking structures on the tongue and palate are actually comprised of soft keratin spikes called papillae. They appear sharp on the top, and curve backwards toward the back of the mouth.
Are penguins deaf?
As in most birds, penguin hearing is probably good, but not as acute as that of marine mammals. Hearing for penguins has not been well researched. One study on African penguins found a hearing range of 100 to 15,000 Hz with a peak sensitivity between 600 to 4,000 Hz.
How smart is a penguin?
Penguins are intriguing creatures for many reasons. They are intelligent, competent, and self-aware beings that can be coached and conditioned. They're also great at making mental maps, recognizing each other's calls, and hunting in groups .
Do penguins have 3 eyes?
The penguin eye has several adaptations that allow penguins to see well on land and out in the ocean. ... Their strong eye muscles change the shape of their eye lens to create a sharp, clear image both on land and in water. In addition to this, penguins have a nictitating membrane, also referred to as a third eyelid.
What is penguin Habitat?
Habitat: Penguin habitats include oceans and coasts. They generally live on islands and remote continental regions with few land predators, where their inability to fly is not detrimental to their survival. They are adapted to living at sea, and some species can spend months at a time at sea.
Do penguins have knees?
But yes, penguins do have knees! A penguin's leg is composed of a short femur, knee, tibia and fibula. The upper leg bones are not visible as they are covered in feathers giving penguins a very short legged appearance. Here you can compare the leg of a penguin skeleton (left) to a model of a human skeleton (right).
Why do penguins make noise?
The first, contact vocalizations, is used to distinguish other members of the colony; the second, threat vocalization, is used to defend their territory and warn the other penguins in the colony about the proximity of a predator; and the third is used to transmit sexual, territorial or individual recognition ...
Why do penguins honk?
The scientists knew from prior research that African penguins honk using three distinct types of sound, reminiscent of human syllables, when greeting one another, mating, or defending territory. ...
How do penguins recognize their mates?
Penguins use their sense of smell to find their mates after feeding at sea, and to return to the same nesting site year after year. The birds also can detect relatives using their sense of smell, researchers at the University of Chicago and the Chicago Zoological Society found.
