As the world's smallest cuckoo, the little bronze cuckoo measures 15-16 centimeters (5.9-6.3 in) in length and weighs 14.5-17.0 grams (0.51-0.60 oz). The females are slightly larger than the males. The generation length of the Little Bronze Cuckoo is approximately three years. The little bronze cuckoo is characterized by its bronze-green upperparts, white underparts with dark barring, and a distinctive white spot behind the eye. It has a slender body and a long tail, allowing it to maneuver swiftly through dense vegetation. In flight, it is described as being direct with subtle undulation. Voice: The little bronze cuckoo has territorial vocalizations that are often called from an unobstructed vantage point. These calls consist of 3-5 repeating notes that lower in pitch towards the end. There are some variants: the repeated notes can sound like "rhew", "eug" or be a screeching trill. The calls of individuals in Wallacea have not been described.
