Question

Why do you think the poet says that the birds were without a nest on earth? (Hint - their name)​

Answer 1

The poet when speaks of birds without a nest on the earth means they have no fixed place on this earth to live. ... They might not need a permanent home here on earth to be bound. They will build a new and temporary nest wherever they go as most of the time they spent is flying in the open skies.
