Pika has an interesting life. When in danger of encountering animals such as feral cats and foxes, which are considered to be the main enemies of this animal, one of his tricks is to take all his children in his mouth on a quiet and safe day and move them to a farther place which is it's new den. In fact, pika with this motherly trick, protects her children from the next attack of it's enemies.
The interesting thing is that this trick is done by many animals when they are in danger, and i have seen this trick many times. wish all the tricks were as beautiful as Pika's trick.
Hope you enjoy from this photo which taken by me.
