Otus angelinae is an owl that known for their silent flight, capable of flying just inches from their prey without being detected. The quietness of their flight is owed to their special feathers. This study aimed to describe the morphology and function of feathers of Otus angelinae. Two Otus angelinae aged 4 months taken from the wild forest of East Java. Owl were sedated with chloroform, dissected, and then observed to know the morphological of feathers that coat its body. The results showed that each part of the body of an owl composed of different morphology and size of feathers to support the activity of flying.
