Birds and Their Features
Grade 1 · Science · Study Guide
Discover what makes birds special and unlike any other animal!
Birds are amazing animals that live all over the world — from icy Antarctica to hot deserts! All birds share some special features that make them different from other animals. Every bird has feathers, two wings, two legs, and a beak. Birds are the only animals with feathers!
Most birds use their wings to fly, but not all of them do. Penguins use their wings as flippers to swim, and ostriches run very fast on their strong legs. A bird's beak is shaped perfectly for the food it eats. Eagles have sharp, hooked beaks for tearing meat. Hummingbirds have long, thin beaks for sipping flower nectar. Ducks have flat, wide beaks perfect for scooping up water plants.
Birds hatch from eggs! The mother (and sometimes the father) keeps the eggs warm until they hatch. Baby birds are often helpless at first and need their parents to bring them food. As they grow, they develop their flight feathers and eventually learn to fly on their own.
| Bird | Beak Shape | Food It Eats |
|---|---|---|
| Eagle | Sharp and hooked | Small animals and fish |
| Hummingbird | Long and thin | Flower nectar |
| Duck | Flat and wide | Water plants and insects |
| Finch | Short and thick | Seeds |
| Pelican | Large with a pouch | Fish |
