Farhan lives near a lake in Udaipur, Rajasthan. Every morning, he watches different birds near the water. He sees a kingfisher diving into the lake to catch fish, a sparrow pecking at grains on the ground, and a crow picking up scraps of roti from a dustbin.
"Why do these birds eat such different things?" Farhan asked his grandmother. She said, "Look at their beaks carefully -- each bird has a beak that is just right for the food it eats." Let us learn about birds and their wonderful beaks.
Features of Birds
Birds are special animals. They have features that make them different from all other animals:
1. Feathers: Birds are the only animals that have feathers. Feathers keep them warm and help them fly.
2. Wings: Most birds use their wings to fly. Some birds like the ostrich and penguin have wings but cannot fly.
3. Beak: Birds do not have teeth. They use their beak (also called a bill) to pick up, tear, crush or filter their food.
4. Claws: Birds have claws on their feet. Different birds have different types of claws depending on where they live and what they eat.
5. Hollow bones: The bones of most birds are hollow (empty inside), which makes their body light for flying.
6. Eggs: All birds lay eggs. The mother bird sits on the eggs to keep them warm until the chicks hatch.
Think about it: Why do you think birds have hollow bones instead of solid bones like us?
Types of Beaks
The shape of a bird's beak tells us what kind of food it eats. Here are the main types:
| Type of Beak | Shape | Used For | Example |
|---|---|---|---|
| Crushing beak | Short, strong, cone-shaped | Cracking seeds and grains | Sparrow, parrot |
| Tearing beak | Sharp, hooked, curved | Tearing flesh of prey | Eagle, hawk |
| Probing beak | Long, straight, pointed | Drilling into wood for insects | Woodpecker |
| Straining beak | Flat, broad with tiny slits | Filtering food from water and mud | Duck, flamingo |
| Catching beak | Long, sharp, pointed | Catching fish from water | Kingfisher, heron |
Think about it: Look at a crow's beak. It is strong and can eat many types of food -- grains, insects, fruit and even scraps. What does this tell you about the crow?
Types of Nests
Birds build nests to lay their eggs and raise their young ones. Different birds build different kinds of nests:
Weaver bird: The weaver bird (baya) builds a beautiful hanging nest using grass and strips of leaves. These nests hang from the branches of palm or babool trees and look like small pouches. You can see them in villages across India.
Tailor bird: The tailor bird stitches large leaves together using plant fibres or spider silk to make a cosy pouch-shaped nest. It is like a tiny tailor sewing cloth!
Crow: The crow builds a rough, platform-like nest using twigs, sticks and wire on tree branches or building ledges.
Woodpecker: The woodpecker drills a hole in a tree trunk and makes its nest inside.
Koel: The koel does not build its own nest. It lays its eggs in the crow's nest, and the crow raises the koel's chicks. This is called brood parasitism.
Bird Migration
Some birds travel thousands of kilometres from cold countries to warmer places when winter comes. This long journey is called migration. India is home to many migratory birds during winter. The Siberian crane travels all the way from Siberia (Russia) to Bharatpur in Rajasthan (Keoladeo National Park). Flamingos visit the Rann of Kutch in Gujarat every year.
Some Important Indian Birds
Peacock: The national bird of India. The male peacock has beautiful, colourful tail feathers and dances during the monsoon season.
Parrot: A bright green bird with a red beak, commonly seen across India. It loves eating fruits, especially guavas and chillies.
Sparrow: A small brown bird that was once very common in Indian cities but is now becoming rare.
Pigeon: A grey bird often seen near temples and old buildings in cities like Jaipur and Hyderabad.

Lakshmi saw a sparrow eating rice grains in her courtyard. The sparrow used its short, strong beak to crack and crush the grains. Later, she saw an eagle flying high above, carrying a mouse in its sharp, hooked claws. The eagle uses its curved beak to tear the food into small pieces before eating.
On a school trip to a village near Pune, the children saw many golden-yellow nests hanging from a palm tree near a pond. Their teacher explained that these were nests of the weaver bird (baya). The male weaver bird builds the nest to attract a female. If she does not like the nest, he builds a new one. The children were amazed at how neatly the grass was woven together.
Every winter, Chilika Lake in Odisha welcomes thousands of migratory birds from faraway places like Siberia, Central Asia and Europe. Birds like flamingos, pelicans and pintail ducks fly thousands of kilometres to escape the harsh cold winter in their home countries. They stay at Chilika Lake for a few months and return when spring arrives.
