The study of feathery bipedal vertebrates is

Options

A. Batrachology
B. Ichthyology
C. Ornithology
D. Teratology

Answer

To solve the question "The study of feathery bipedal vertebrates is", we need to identify the correct branch of biology that corresponds to the description provided. Here’s a step-by-step breakdown:

### Step 1: Understand the Key Terms
- **Feathery**: This indicates that the organisms in question have feathers, which is a characteristic feature of birds.
- **Bipedal**: This means that the organisms walk on two legs, which is another characteristic of birds.
- **Vertebrates**: This term refers to animals that have a backbone, which includes birds, mammals, reptiles, amphibians, and fish.

### Step 2: Analyze the Options
1. **Patrocology**: This is the study of amphibians. Since amphibians do not have feathers and are not exclusively bipedal, this option is incorrect.

2. **Ichthyology**: This is the study of fish. Fish are not bipedal and do not have feathers, making this option incorrect as well.

3. **Teratology**: This branch deals with the study of abnormal development and its causes. It does not specifically relate to the study of birds, so this option is also incorrect.

4. **Ornithology**: This is the branch of zoology that specifically focuses on the study of birds. Since birds are feathery, bipedal vertebrates, this option fits perfectly.

### Step 3: Conclusion
Based on the analysis of the options, the correct answer to the question is **Ornithology**, as it is the study of birds, which are the feathery bipedal vertebrates described in the question.

### Final Answer
The study of feathery bipedal vertebrates is **Ornithology**.
