To answer the question "The skull of birds is?", we will analyze the characteristics of the bird skull and the options provided. ### Step-by-Step Solution: 1. **Understanding Skull Types**: - The skull can be classified based on the number of occipital condyles present. Occipital condyles are the rounded ends of the skull that articulate with the vertebral column. 2. **Identifying Bird Skull Characteristics**: - Birds have a specific type of skull known as monocondylic. This means they possess a single occipital condyle. 3. **Function of Monocondylic Skull**: - The presence of a single occipital condyle allows birds to have a greater range of motion in their neck. Birds can rotate their heads up to 270 degrees due to this structure. 4. **Evaluating Other Options**: - The other options provided are dicondylic and amphicondylic. - Dicondylic skulls are found in mammals and amphibians, which have two occipital condyles. - Amphicondylic is not a recognized term in this context, as there are only monocondylic and dicondylic skulls. 5. **Conclusion**: - Based on the analysis, the correct answer is that the skull of birds is monocondylic. ### Final Answer: The skull of birds is monocondylic. ---
