During winters, birds find it very difficult to get food. We should do something to help them. We can make a bird-feeder. First, put some glue on a plastic bottle. Then put some moss on it and let it dry. After that, stuff the bottle with seeds or nuts. Then, tie a string through the moss and hang the bottle with its neck facing downwards. The firmly packed food inside the bottle will not fall out and the birds will enjoy pecking out the seeds from the bottle. Soon, you will see many birds crowding around the bottle. Birds also love to eat berries and bread crumbs. You can also give the birds water to drink in winters. Keep the bird-feeder at a safe distance from your house and out of the sun.
