Let’s check out more on pikas.
How was pika discover?
Li Weidong discovered pikas in 1983. He and his team were the first people to observe this animal. After 3 years of research, they name this little rabbit pika. They found pikas on the west side of China’s Xinjiang province. A total of 29 pikas were sighted until 2015.
The population of pikas was decreased by 70% within 15 years. There are many reasons for the decrease of this innocent little animal.
Pikas are herbivores. They like to eat tail wildflowers. Grasses, forbs, small shrubs, and weeds grow in their habitats. Pikas fulfill the water requirements through consumed plants.
Pikas are famous for their innovative haymaking behavior.
Pikas make mated pairs each year before snowmelt. A female pika can give birth to two to four pups. They depend completely on their mother for about 18 days. These small pups are blind and they open years after nine days from birth. They can head out on their own by four weeks old.
What are the threats to pikas?
Climatic changes are one of the major threats for pikas. Global warming highly affects the lives of these innocent animals. The increase of average temperature and frequency of high-temperature events cause pika mortality due to overheating. Exposure of pikas to temperatures more than 77 degrees can cause death. They are considered as an indicator species for climate change. Their habitats shift upslope as a result of the increasing temperature.
Livestock grazing and human disturbances are also threats to the lives of pikas.
Who is the predator of pika?
Pika has sharp eyes and hearing. So they get the signals about predators quickly. The whole group of these animals is sensitive to the signal of each other. Just after getting a signal from one member, the whole colony dives into their burrows. They also get into the tiny spaces between the rocks to escape. They are sensitive to the alarm signals of ground squirrels and marmots. Pikas immediately look up and try to figure out the threat.
Ermine is one of the famous predators of pikas. They can easily hunt pikas by entering the burrows or rocks. Marten can also hunt pikas. Hawks, owls, and eagles are the other predators who used to hunt pikas.
Pika tends to respond to predators in different ways. They become silent to avoid the attention of a predator. But pika tends to help each other by giving signals whenever they see a predator.
Parasites like botflies live in the skin of pikas. They tend to hatch eggs on pikas. Mites, nematodes, and fleas are other parasites that tend to bother the lives of this animal.
