Sparrow Escape

Sparrows in general are very harmless birds and that is the reason people adore these little birds. In fact, these birds love to stay around places inhabited by human beings. However, someone for some reason is convinced that a sparrow is very dangerous and so he has trapped the little bird in a cage. I wonder what made him believe this. It is a heartbreaking sight to see the poor bird chirping away from the cage. The selfish man is not to be seen anywhere around. This is the best time to rescue the bird. Can you help me set the bird free?
