From them, we can all take wisdom, how can they be peaceful in a family, they are animals. how about otherwise. we as humans, we are perfect beings on this planet. we can judge ourselves each. whether we with family can feel pleasure, as they (the bird) feel.
If we are also family, we can also judge whether we have a sense of responsibility towards our own family. and also whether we are fair, both love and sharing things or other things.
As an afterthought, in this post you can see, a bird (type of sparrow) distributes food for their children.
