Pika

The pika is a small animal.

It lives in cold mountains. It looks like a round rabbit with short ears.

Pikas like to live on rocky slopes. They eat plants like grass and flowers. In the fall, they gather food. They hide hay under rocks.

This helps them stay full in winter. Pikas do not sleep through the winter. They stay active in the snow. They eat their stored plants to stay strong. They are very busy animals.

Pikas are part of the lagomorph group. This is the same group as rabbits. They are the smallest lagomorphs. Pikas have round bodies and short ears. They also have no tail.

Most pikas live on rocky slopes. They eat grasses, flowers, and stems. Pikas do not hibernate. Instead, they use a way called haying. They gather plants and store them under rocks.

They eat this stored food during the winter. This keeps them active in the snow. Pikas make high calls to warn others. People call them whistling hares for this reason.

Some pikas live alone. Others live in family groups. Pikas like cool weather. They stay in the shade when it is hot. If it gets too warm, they may lose time for gathering food. This can make it hard to store enough food for winter.

The pika is a tiny mammal that lives in cold places.

You might think they look like rabbits. They are part of the lagomorph group, just like hares and rabbits. However, pikas are much smaller than their cousins. They have very round bodies and short limbs. Their ears are also short and rounded instead of long. Most pikas do not have an external tail. They live in mountains across Asia and North America. Some live very high up in the Himalayas.

To survive the long winter, pikas have a clever way of working. They do not hibernate like some other animals. Instead, they use a process called haying. During the autumn, they gather grasses, flowers, and soft twigs. They pull these plants into piles to dry. Then, they hide these haypiles under rocks for later.

This stored food keeps them alive during the cold months. They spend the winter traveling through tunnels under the snow. This helps them stay active even when it is freezing outside.

Scientists have studied pikas for a long time. The name pika likely comes from the Tungusic word "piika." Their scientific name, Ochotona, comes from a Mongolian word. This word is "ogotno," which means pika. Many different types of pikas have lived on Earth. Some lived a very long time ago during the Miocene epoch. We know about many extinct species from fossils. One type, the Sardinian pika, disappeared about 2,000 years ago. This happened because of human activity.

There are many different facts about how pikas live. Most pikas weigh between 200 and 400 grams. They are usually about 15 to 25 centimeters long. Pikas have a special way of getting nutrients from plants. They use a part of their gut called a cecum to ferment fiber. This creates soft pellets called cecotropes. The pika then eats these pellets to get more energy.

This is called cecotrophy. It is a common behavior for all lagomorphs.

Watching a pika can be a very interesting experience. You might hear them before you see them. They are sometimes called whistling hares. This is because they make high-pitched alarm calls. They use these sounds to warn others about predators. They also use calls to find mates or defend their space. Pikas really love the cold. If the temperature rises by just 2 degrees Celsius, they lose 3% of their foraging time. This makes it much harder for them to collect food for the winter.

The pika is a small mammal that lives in cold, mountainous regions.

It belongs to the family Ochotonidae. This family is part of the order Lagomorpha. This order also includes rabbits and hares. However, pikas are the smallest animals in the lagomorph group. They have round bodies, short limbs, and short, rounded ears. They also lack an external tail.

Pikas are found in Asia and North America. Some species live in the Himalayas at elevations over 4,000 meters.

Pikas have a very specific way of surviving harsh winters. Unlike many other small mammals, pikas do not hibernate. Instead, they use a method called "haying." During the autumn, they gather grasses, flowers, and soft twigs. They pull these plants into piles to dry. They then store these haypiles under rocks.

This stored food allows them to stay active all winter. They travel through tunnels under the snow to find their food caches. This behavior ensures they have nutrients even when the ground is frozen.

To get energy from tough plants, pikas use a special digestive process. They eat many types of plants like grasses, moss, and lichens. These plants contain hard-to-digest fiber. To handle this, pikas use a part of their gut called a cecum. In the cecum, they ferment the fiber. This process produces soft pellets known as cecotropes. The pika then reingests these pellets.

This process is called cecotrophy. It allows them to absorb nutrients in the small intestine that would otherwise be lost.

There are 37 living species within the genus Ochotona. These species are divided into different subgenera. The subgenus Conothoa includes mountain pikas, such as the Large-eared pika. The subgenus Ochotona includes shrub-steppe pikas like the Plateau pika. There is also a subgenus named Pika, which includes the American pika.

North American pikas include the American pika and the collared pika. While many species live in family groups, some North American species are asocial. This means they live solitary lives outside of the breeding season.

Scientists have a long history of studying pika fossils. Many extinct genera of Ochotona have been found. These fossils date back to the Miocene epoch. Some extinct species lived in Europe, Asia, and North America.

One notable extinct species was the Sardinian pika. It belonged to the genus Prolagus. This species went extinct within the last 2,000 years due to human activity. The fossil record shows that pikas have inhabited many different environments over millions of years.

Pikas are highly sensitive to their environment. They prefer temperatures below 25 degrees Celsius. Because of this, they spend much time in shaded areas. Changing temperatures can be very dangerous for them. For every 2 degree Celsius increase in ambient temperature, pikas lose 3% of their foraging time.

If they lose foraging time, they cannot collect enough food for winter. Human activity and rising temperatures may force populations to move to higher elevations. This shift can limit their available habitat.

Pikas are also known for their unique communication. They are sometimes called "whistling hares." This name comes from their high-pitched alarm calls. They use these calls to warn others about predators. They also use vocalizations for individual recognition and to defend territory. In the spring, their songs become more frequent during breeding season. These sounds are so distinct that scientists use them as a taxonomic tool. This helps researchers identify and classify different species based on their unique acoustic patterns.
