Explanation

To determine the origin of the furcula in birds, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**:
- The furcula is a structure found in birds, and it is commonly referred to as the "wishbone." It plays a significant role in the anatomy of birds, particularly in relation to flight.

2. **Identify the Relevant Anatomy**:
- Birds belong to the phylum Aves and have various adaptations for flight. One of these adaptations is the modification of their skeletal structure.

3. **Examine the Pectoral Girdle**:
- The pectoral girdle is a key component in birds that supports the wings. It typically consists of the clavicles (collarbones) and other bones that provide attachment points for flight muscles.

4. **Recognize the Role of the Furcula**:
- The furcula is specifically associated with the pectoral girdle. It serves as a brace for the shoulder joint and provides an attachment point for the breast muscles, which are crucial for flight.

5. **Conclude the Origin**:
- Since the furcula is derived from the pectoral girdle and serves an important function in the flight mechanism of birds, we can conclude that the furcula is from the pectoral girdle.

### Final Answer:
The furcula of birds is from the **pectoral girdle**.
