Due to plant and animal diversity, different environments are created in the immediate surroundings of the house. Diverse kinds of plants and animals exist in various eco-systems in Sri Lanka because of the nature of land and climatic conditions. Plants are very useful for the existence of living beings. If you are living in a rural environment, you may find plants in abundance. Eventhough you live in an urban environment, you can beautify the immediate surroundings of your house by growing plants. When selecting plants, you should consider not only their beauty but also whether they are suitable for the environment and the health of the man.
The species of animals that live facing the challenges of the hot sun, rain, threats from enemies and diseases are also a part of our environment. Animal community is also important for the existence of man.
You may have noticed some special kinds of birds in the environment of your house during certain periods of the year. Some species of birds are found only in a particular period. The singing of the koha bird or the Asian koel during the season of the Sinhala and Tamil New Year is familiar to you.
Sometimes, we see some birds migrating to our country during the winter season as they are unable to bear the coldness there. Those birds are migrant birds. Indian Pitta, Paradise fly catcher (Sudu Redi Hora) and Sivuru Hora are examples for migrant birds.
