These birds are just like humans. Why, you ask? The two parakeets that are flying look like performers and the two birds sitting on the chimney are the audience. (The bird sitting nearest to the performers has the VIB [Very Important Bird] seat)
This is my favorite image taken on the outskirts of Bangarpete, where my father spotted many birds sitting on the chimneys of brick factories. Since there are many large brick factories in this area, we found many, many chimneys with flights of birds on them.
