IV. Short Answer Questions

Woodpeckers have a chisel-shaped beak because its sharp, long, and pointed design allows them to poke holes into the hard trunks of trees and pull out insects to eat.

Webbed feet help a duck to swim effectively by allowing it to push more water backward with each stroke. The skin between their toes creates a larger surface area, similar to a paddle, which propels them through water.

Birds use various materials to build their nests, such as twigs, leaves, wool, cotton, straws, thread, and pieces of cloth or paper. (Any two are acceptable.)

In bird flight, an ‘upstroke’ is the upward and backward movement of the wings, while a ‘downstroke’ is the downward and forward movement of the wings. Both movements are essential for generating lift and propulsion.

It is important to clean a bird bath regularly because birds use the same water for both bathing and drinking. Regular cleaning ensures the water remains fresh and clean, preventing the spread of diseases among birds.

V. Diagram-Based Question

This is a webbed bird foot.

This kind of foot is typically found in swimming birds, such as ducks and swans.

The webbed structure helps the bird move effectively in water by increasing the surface area of the foot when pushed backward. This allows the bird to push a greater volume of water with each stroke, creating efficient propulsion for swimming.

VI. Long Answer Questions

A bird’s body is uniquely designed for flight. It has a streamlined shape, narrow at the ends and broad in the middle, which helps it cut through the air and reduce resistance. Birds fly using their powerful wings, which are attached to strong muscles. Flight involves two main movements: the upstroke, where wings move upward and backward, and the downstroke, where they move downward and forward. The bird’s tail also plays a crucial role in steering and changing directions during flight.

Nests are incredibly important for birds as they serve as safe homes for laying eggs and protecting their young from predators. Bird parents incubate the eggs by keeping them warm until they hatch, and then they feed the baby birds until they are strong enough to fly independently. Different bird species have unique nesting habits. For example, the tailor bird is famous for literally “sewing” leaves together with its beak and thread to form a cozy nest, while the weaver bird constructs intricate, strong nests by weaving grass and twigs that often hang from tree branches.

VII. Environmental Awareness

It is important for humans to care for animals because they are a wonderful part of our lives, bringing joy and companionship, and they, like us, need food, water, and a good environment to thrive. Two ways we can take care of pets are:

Feed them at regular intervals and ensure their dishes are clean.

Take them for regular check-ups to a veterinary doctor.
