**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term that describes the arrangement of feathers on the body of birds.

2. **Identifying the Term**: In the context of birds, the specific arrangement of feathers is referred to as "Tectrices." However, based on the video transcript, the term used is "Terry losses," which seems to be a mispronunciation or confusion with "Tectrices."
