Do you think the birds are an important part of the environment? As per chapter 16 class 4 EVS book.

Birds are being given the same importance in our nature as the other animals unfortunately forest degradation and other changes in the climate and areas are a major reason for their extinction. Bird play important role in nature and that is why various important steps are being taken for the birds.

Why do you think the summers are the busy month for birds to make their nests as per the story in unit 16 from class 4 EVS NCERT?

Nest is important for any of the birds or animals for say. During summers the availability of dry twigs and leaves is high. On top of that, the nest is built so that they can lay eggs for their offspring and in winters either they migrate or try to arrange food for their chicks. Which makes them busy in summer.

What are the most interesting thing about the chapter 16 class 4 EVS?

The most interesting part that I can study in this chapter was to study the birds and their types of nests. Few of them achieve the precision of making a nest that is even tough for a human to make.

Do you find unit 16 of class 4 is entertaining?

The chapter is quite interesting as after reading so many things about the environment I think the birds are the best part as it is quite interesting how these little creatures make their work done.
