For a scene that the author "supposedly" saw, it is very identical to the source you have found.

Read your paragraph:

When I go to the balcony of the room I am in, I see a mango tree that has grown taller than my room. These days, I can see how a couple of birds have made a nest and laid eggs at the end of a branch of the mango tree towards my room. When I wake up in the morning and come out of the room, I can see the scene directly. It can be seen that the couple do the work of keeping the eggs with great dedication. Both of them can be seen eagerly waiting for their babies to come out of the eggs. So today I thought of drawing this couple of birds for this contest. Let's see step by step how I draw this picture.
