The pika is a small-sized mammal that is found across the Northern Hemisphere. Despite their rodent-like appearance, pikas are actually closely related to rabbits and hares.Pikas are most commonly identified by their small, rounded body and lack of tail. Pikas prefer the colder climates and are generally found in mountainous regions and rocky areas where there tend to be fewer predators.ikas defend their territory by whistling to one another, and their large, rounded ears come in useful to hear the calls from competing pikas. Pikas are herbivorous animals and the pika therefore has a diet based on vegetation.
