The New Zealand Wren, also known as the Titipounamu, is a small bird species that is endemic to New Zealand. Some synonyms for the New Zealand Wren include the Rifleman, Green-rumped Wren, and Ngutuparore. The Rifleman name comes from its distinctive habit of darting from branch to branch like a rifle bullet. Meanwhile, Green-rumped Wren describes the bird's green feathers on its rump. Lastly, Ngutuparore is a Maori name for the bird, which refers to its small size and agility. Despite these names, the New Zealand Wren is not a true wren but belongs to a unique family of birds, the Acanthisittidae.
