Brothers Saud and Nadeem were raised looking at a sky speckled with black kites, watching as relatives tossed meat up to these birds of prey. Muslim belief held that feeding the kites would expel troubles. Now, birds are falling from the polluted, opaque skies of New Delhi and the two brothers have made it their life’s work to care for the injured black kites. Shaunak Sen’s intricately layered portrait reveals an evolving city and a fraternal relationship bonded by purpose. The film’s patient, roaming camera skillfully uses scale and perspective to draw attention to the interconnectedness of an ecosystem — one that humans are a part of, not apart from. The social unrest that begins to materialize in the streets is seen through the perspectives of the brothers and their family, as well as the insects and animals that share the urban landscape. There is both cruelty and tenderness in nature, and Sen elegantly captures how they coexist, while emphasizing the ways in which all living beings must evolve to survive.
