A Bird's Masterpiece

           A bird nest is the spot in which a bird lays and incubates its eggs and raises its young. Their nests are made out of twigs and weeds I guess. Birds make their nests carefully. 
          I have witnessed a bird making its nest in our own house. And it was so cool! I didn't watch it make it the whole day though. We had classes. But maybe after 3 or 4 days, I saw its result! It was really cool! It had a small door for it and maybe its young.
