To identify which animals are endothermic, we need to understand the term "endothermic." Endothermic animals, often referred to as warm-blooded animals, can regulate their body temperature internally, regardless of the environment.

1. **Birds**: All birds are endothermic. They maintain a constant body temperature despite fluctuations in the external environment.

2. **Mammals**: All mammals are also endothermic. Like birds, they can internally regulate their body temperature and have various adaptations to help them do so.

3. **Reptiles and Amphibians**: Both reptiles and amphibians are generally ectothermic (cold-blooded). They rely on external environmental conditions to regulate their body temperature.

4. **Fish**: Most fish are ectothermic as well, although there are a few exceptions in certain species that can maintain a higher body temperature.

Given these definitions, the correct answer from the given groups would be:

### Final Answer
**Birds and mammals**.
