TOPIC- Birds.

Content

Birds are the most beautiful and colourful creatures

on the earth. We all love to watch them flying in the

sky and listening to their sweet voices. Some birds

eat flesh while some eat grains, seeds and fruits.

BODY PARTS OF BIRDS

All birds are like in certain ways and have some common

body parts. Birds have feathers all over the body. Their

body consists of head, wings, tail and legs. They have

beak with nostril. They do not have teeth. Their body is

shaped like a boat. This shape helps it to cut through air.

The bones of the birds are hollow which makes their

body light. Just we have arms, a bird has wings. The

wings are attached to the bird’s body with string

muscles. These muscles help it to move the wings up and

down or forward and backward.

FEATHERS OF BIRDS

Down feathers

These are fluffy feathers close to the skin of the bird.

Down feathers keep the birds warm.

Flight feathers

The long, flat feathers attached to the wings and tail help

the bird to fly and to change the direction.

Body feathers

Body feathers cover the bird’s body.

Creepy Crawlies

They crawl, slither, fly, wriggle, and squirm into your garden. These

little buggers are here to help. Don't kill them—consider them your

friends!

1. GROUND BEETLES

There are 40,000 different species. Rarely flying and often black,

these insects have a tough shell to protect them from predators while

they're hunting prey themselves. They get rid of garden pests like

aphids, flies, maggots, slugs, and other creatures who destroy your

garden.

2. LADYBUGS

The beetles—whose bright colors discourage predators from eating

them—are also attracted to gardens by flowers like marigolds and

plants.

3. DAMSEL BUGS

These long-beaked bugs are so great for your garden. Once in your

garden, they'll grab small caterpillars, leaf hoppers, aphids, and

beetle larvae with their front legs and use their beaks to suck them

dry.

4. GREEN LACEWINGS

As adults, these beautiful insects typically prefer pollen and nectar.

They also take care of mealy bugs, spider mites, and insect eggs.

5. SPINED SOLDIER BUGS

They prey on more than 100 species, including pests like the larvae

of cabbage worms. They can be identified by the "spikes" on each

shoulder.

6. HOVERFLIES

These yellow- and black-banded flies have looks and a diet in

common with bees but they can't sting you. Adult hoverflies are also

sometimes known as "sweat bees" because, in dry years, they'll land

on people and drink a little of their sweat.

7. EARTHWORMS

A healthy garden starts with a good base, and earthworms will help

with that. These invertebrates eat their way through dirt, loosening

soil to introduce water and air, which in turn helps roots to grow.

The worms remove debris on the surface of gardens—like dead

grass—and excrete nutrient-rich castings, which will fertilize your

plants.
