### Step-by-Step Solution:

1. **Understanding the Question**: The question asks which plant is pollinated by hovering birds, specifically hummingbirds.

2. **Identifying Hovering Birds**: Hovering birds are primarily hummingbirds, known for their ability to hover in front of flowers while feeding.

3. **Characteristics of Hummingbirds**: Hummingbirds are attracted to bright-colored flowers that produce nectar. They have long beaks that allow them to feed on nectar without landing on the flowers.

4. **Definition of Pollination by Birds**: The process of pollination carried out by birds is known as ornithophily.

5. **Analyzing the Options**:
- **Option 1: Pycnonia**: This plant is known to be pollinated by hummingbirds. Therefore, it is a correct option.
- **Option 2: Peepal**: This plant does not have flowers suitable for hummingbird pollination, making it an incorrect option.
- **Option 3: Magnolia**: This plant primarily relies on wind for pollination, so it is also an incorrect option.
- **Option 4: Bougainvillea**: Hummingbirds do not pollinate Bougainvillea, making this option incorrect as well.

6. **Conclusion**: The correct answer is **Pycnonia**, as it is the only plant listed that is known to be pollinated by hovering birds (hummingbirds).

### Final Answer:
**The correct option is Pycnonia.**
