C. Tick (✓) the correct option.
1. A sparrow uses its short and hard beak for—
(a) sucking nectar from flowers
(b) sifting food from mud
(c) catching flies while flying
(d) crushing of grains
Answer: (d) crushing of grains
Explanation: Sparrows have short, thick, conical crushing beaks designed to crack hard grain shells and seeds.
2. A hoopoe takes out insects and worms from the holes in the ground with the help of its—
(a) strong, short and straight beak
(b) long and slender beak
(c) broad beak that has holes on the sides
(d) curved and hard beak
Answer: (b) long and slender beak
Explanation: The hoopoe has a long, slender probing beak that reaches deep into soil holes and crevices to extract insects.
3. A bird, that does not have strong and sharp claws, is the—
(a) eagle
(b) duck
(c) vulture
(d) hawk
Answer: (b) duck
Explanation: Ducks have flat, webbed feet for paddling in water, whereas eagles, vultures, and hawks have sharp talons for seizing prey.
4. Birds, that have two toes pointing upwards and two downwards, are known as—
(a) scratching birds
(b) wading birds
(c) climbing birds
(d) perching birds
Answer: (c) climbing birds
Explanation: Climbing birds like woodpeckers and parrots have two toes pointing forward/upward and two backward/downward to cling securely to tree bark.
5. It is a perching bird—
(a) sparrow
(b) jacana
(c) hen
(d) duck
Answer: (a) sparrow
Explanation: Sparrows, pigeons, and crows have three toes in front and one behind that curl around twigs and perches, holding firmly even while asleep.
D. Answer the following questions in brief.
1. What do birds use for preening their feathers?
Answer: Birds use their beaks to clean, smooth, align, and preen their feathers.
2. How is a crushing beak helpful to a pigeon?
Answer: A short, strong, and hard crushing beak allows pigeons to easily crack and crush tough seeds, nuts, and grains into digestible pieces.
3. What are claws?
Answer: Claws are the hard, curved, sharp horny nails present at the tip of each toe on a bird’s feet.
4. Name three birds of prey.
Answer: Eagle, Hawk, and Vulture.
5. What prevents the body of crane and jacana from sinking in water?
Answer: Their long legs with widely spreading, slender toes distribute body weight over a large surface area, allowing them to wade smoothly through shallow water and soft mud without sinking.
E. Answer the following questions.
1. Write two main uses of a beak of a bird.
Answer: Two major uses of bird beaks are:
- Procuring and Consuming Food: Used to catch, tear, crush, sift, or probe for food, as well as to feed their baby chicks.
- Nest Construction and Defense: Used to collect twigs and grass to weave nests, preen feathers, and protect themselves against predators.
2. How are claws helpful to a bird?
Answer: Claws help birds in several essential ways:
- Holding Branches (Perching): Helping birds grasp wires and twigs firmly while perching and resting.
- Seizing Prey: Strong, curved talons allow birds of prey (eagles, hawks) to grab and kill small animals while flying.
- Locomotion: Assisting in swimming (webbed feet of ducks), climbing tree trunks (woodpeckers), or scratching soil for food (hens).
3. How does a swallow catch its food?
Answer: A swallow has a short, broad beak that is sticky inside. It flies at high speed through the air with its mouth wide open. Tiny airborne insects and flies get stuck inside its sticky mouth and are swallowed without stopping.
4. How do webbed feet help a duck to swim?
Answer: In ducks, the three front toes are joined together by a thin web of skin. When the duck pushes backwards in the water, these flat webbed feet act like oars or paddles, pushing a large volume of water backwards and propelling the duck smoothly forward.
5. What type of feet do the scratching birds have?
Answer: Scratching birds (like hens and quails) have strong, sturdy feet with three long toes pointing forward and one short toe pointing backward. Each toe ends in a hard, sharp, curved claw suited for scratching and digging through soil to uncover buried seeds and worms.
Value-Based Questions
Neha was travelling with her family in a car. On the way, she noticed that some children, going in another car, were throwing out banana and orange peels out of the car window. She did not like this at all. When they all stopped at a restaurant on the way, Neha went to those children and told them that they should not behave in a way that makes the environment dirty. She told them that in nature also, birds, like vultures, eat away dead animals to keep the environment clean. The children realised their mistake.
1. What kind of good habits does Neha have?
Answer: Neha has excellent civic sense, hygiene consciousness, courage to correct others politely, and respect for environmental cleanliness.
2. Why is it important for all of us to keep our environment clean?
Answer: Keeping our environment clean prevents the accumulation of garbage, stops breeding of disease-spreading mosquitoes and houseflies, prevents water and soil contamination, and ensures healthy, disease-free communities.
3. How do vultures help in cleaning the environment? What kind of beaks do these birds have?
Answer:
- Vultures act as natural scavengers by eating dead animal carcasses, preventing foul smells and outbreaks of dangerous infectious diseases.
- They have strong, sharp, curved, and hooked beaks specially adapted for tearing and ripping tough flesh from bones.
Something to Do
1. Bird Scrapbook: Collect pictures of different common birds (sparrow, pigeon, woodpecker, eagle, duck, crane). Paste them in a scrapbook and label their type of beak and claw alongside their primary diet.
2. Morning Bird Observation: Spend 15 minutes during early morning in your balcony or garden. Listen to different bird calls and observe how sparrows perch on wires and how pigeons feed on scattered grains.
