Darzee the tailor-bird initially helps Rikki-Tikki at the beginning of the short story by warning him about Nagaina's ambush. While Rikki-Tikki is speaking to Nag for the first time, Nagaina sneaks up behind him and Darzee yells "Behind you! Look behind you!" to Rikki-Tikki, who instantly jumps into the air to avoid Nagaina's attack. After Rikki-Tikki kills Nag, he asks Darzee where Nagaina is located and she tells him that Nagaina is mourning her deceased husband by the rubbish heap. Darzee then informs Rikki-Tikki that Nagaina's eggs are located in the melon bed, on the end nearest the wall. Darzee once again helps Rikki-Tikki by acting like she broke her wing to get Nagaina's attention while Rikki-Tikki destroys her eggs in the melon bed. Overall, Darzee helps Rikki-Tikki by warning him about Nagaina's ambush, telling him where Nagaina hides her eggs, and distracting Nagaina by feigning a broken wing, which gives Rikki-Tikki time to destroy Nagaina's eggs.
