Animal and Birds Senses

Updated on December 20, 2016

Alert Deers

Alert Deer

The fact that animals have more sense than humans was proved during the recent Tsunami. Animals could sense the danger and escaped far away from the shores. Records show that very few animals died in the Tsunami.

Alert Deer

You see, at a herd of deer grazing peacefully. All of a sudden they stop grazing and look up. The next moment they all run and a few seconds later, a tiger is seen running after them. However, the tiger is a bit late and the deer run away very swiftly.

How did the deer spot the tiger before it appeared?

Predators (the animals that hunt deer) have their own body odor, which a deer can smell from a distance.

A deer has a large nose, which is moist, both inside and outside. This moisture traps the odors (or scent particles) and the odor (smell) is conveyed to its brain. The deer lick its nostrils to keep it wet so as to quickly catch the odor or scent. Thus, a deer can smell’ an enemy long before he is sighted.

A deer has a pair of large cupped ears, which turn back and forth all the time to hear the faintest of sounds. When a faint sound is heard, the deer will slowly turn towards the direction of the sound. The faint sound of a foot stepping on the fallen leaves or the snap of a twig the chatter of a squirrel or the shrill scream of a blue jay is immediately detected and the deer are fully alert.

Tiger Prowls

Tiger Prowls

The tiger usually hunts at night. It depends on its sharp eyes and keen ears. It also uses its sense of smell.

Tigers, like humans, were forward facing eyes. This helps them to see objects very clearly and to estimate the distance of the prey.

A tiger’s eye has large lenses and pupils that increase the amount of light entering into the eye. This gives the tiger sharp night vision en when there is dim light.

Ears have sharp hearing. Their ears swivel to the left and right to detect various sounds produced by the prey in the dense forest.

Cat and Dog

Cats and Dogs

Cats can see clearly even in poor light. They can see better than humans at night. Both dogs and cats can hear high – pitched sounds which humans cannot hear. They swivel their ears in the direction of the sound to locate it. Both the animals can identify different smells.

Bats use echolocation

Small, quick -moving insects are food for bats. Bats are active at night, dust and dawn. This is the time when their food (insects) is available in plenty.

Bats can also find food (insects) up to a distance of 18 feet, away. They know the type of insect close to them for their sense of echolocation.

A bat produces a sound from its nose or mouth waits for the sound to hit an insect and travel back. The echoes it hears helps it to locate the prey and get it for food.

Bird Eye

Hawk Eye and Bird Calls

A hawk can see small rodents on the ground from a height of 15,000 feet. Its sharp sight helps it to catch’ live food. A hawk’s eye has one million simple eye per sq mm!

Birds can see from a long distance. They can judge how far an object is while flying high up in the sky. They can spot their prey, even if it is very far away.

Birds’ sense of hearing is also good. The Koel is known for its melodious voice which it uses to attract female Koels. Some Birds use their vocal ability to `tell’ others that the particular place belongs to them. Birds like the Orientally White – Eyes, the Seventh -Sisters and many other small birds which flock together keep in touch with each other with their soft calls, as they hop among bushes and branches searching for food.

Ant Sense

Ant Sense

Ants use their antennae to smell, touch and taste’ and know what is around them. They have hair – like feelers called antennae with which they `feel’ around to find food. When food is found, they touch the other ants to to lead them to the food source. As they carry food to the nest, they make a path by using a strong odor – a chemical signal. This path is used by other ants to get to the food.

Some ants give out chemical signals when they are in danger, such as the presence of an unknown insect near their nest. This alert others in the nest and they jointly tackle the enemy’.

Fooling mosquitoes

Mosquitoes locate us by our body odor (especially foot odor), the carbon dioxide we breathe out and our body heat. You can fool the mosquito by covering your feet and by applying a cream to your body surface!

Water Animals

Seeing Under Water

When diving under water, can you see anything in the water? Seeing is very important for animals under water. Most fishes, turtle, ducks, geese, cranes, seals and dolphins can see underwater and find food – insects or plants or smaller fishes. They can also sense a change in smell! When a fish is injured and its skin is damaged, it gives out a particular odor from the damaged skin which is noticed by the other fishes. The other fishes, then swim away from the injured fish fear of unknown danger.
