Answer

### Step-by-Step Text Solution:

1. **Warm-blooded Animals**: Birds are warm-blooded, meaning they can regulate their body temperature internally, maintaining a constant temperature regardless of the environment.

2. **Body Covered with Feathers**: One of the most distinctive features of birds is that their bodies are covered with feathers. Feathers provide insulation, aid in flight, and play a role in mating displays.

3. **Presence of Beak**: Birds possess beaks (or bills) instead of teeth. The shape and size of the beak vary among different species and are adapted to their feeding habits.

4. **Lay Shelled Eggs**: Birds reproduce by laying eggs that have hard shells. This adaptation protects the developing embryo and allows for survival in various environments.
