Q1.
In small groups, collect twigs, leaves and soft materials like cotton or paper available around you. Create a small bird’s nest using the materials. What makes a good nest? What does the nest need to keep the eggs safe?
Answer
A good nest is a strong bowl on the outside and a soft cup on the inside. Build it in that order and it works — build it the other way and it falls apart.
Step 1 — Collect. Only pick up things that have already fallen. Do not break anything off a living plant.
| Layer | What to collect | Its job |
|---|---|---|
| Outside | Thin dry twigs, coconut-leaf ribs, stiff grass stalks | Makes the frame and holds the shape |
| Middle | Dry leaves, soft grass, thin roots, jute string, coir | Fills the gaps and binds the frame together |
| Inside | Cotton wool, feathers, torn soft paper, wool ends | Cushions the eggs and keeps them warm |
Step 2 — Build it, step by step.
- Bend three or four long twigs into a circle and twist the ends together. This is the rim.
- Weave shorter twigs in and out across the circle, over one and under the next, until you have a rough floor.
- Press the middle down with your fist so it becomes a bowl, not a plate.
- Poke dry grass and leaves into every gap, from the outside, until no light shows through the bottom.
- Line the inside with cotton, feathers or soft paper. Press it smoothly all round the cup.
- Check the shape: the rim must be higher than the middle, so an egg rolls back in instead of out.
Step 3 — Test it. Put a small stone or a marble in as a pretend egg, then tilt the nest gently to one side. In a good nest the marble rolls back to the middle. In a flat one it rolls straight out. Then hold the nest by its rim — a good nest holds together and does not sag.
What makes a good nest?
| A good nest is… | Why |
|---|---|
| Deep and cup-shaped | The eggs roll to the middle instead of rolling out in the wind |
| Strong at the rim | It must hold the weight of the parent bird sitting on the eggs |
| Soft inside | An eggshell is thin. Twigs would crack it |
| Warm and closed at the bottom | Eggs need steady warmth to hatch |
| Dry, or able to drain | Rainwater must run off or through, not collect |
| The same colour as its surroundings | Twigs, grass and mud hide it from crows, cats and snakes |
| Light but firmly fixed | It must not blow down; birds wedge it into a fork or hang it from a branch |
| Just big enough | A small cup is easier to keep warm than a large one |
What does the nest need to keep the eggs safe?
- Deep sides, so eggs cannot roll out.
- A soft lining, so the shells do not crack.
- A high, hidden place, out of reach of cats, dogs, snakes and hands.
- Camouflage — the same colours as the branch around it.
- Shelter from sun and rain, usually a leafy branch above.
- A strong hold on the branch, so wind cannot shake it down.
- The parent bird, which is really the most important part of all.
What you learn by making one: Try it and you will find out how hard it is. You have two hands, glue and scissors; a bird has only a beak, and works in the wind, with no plan drawn out. A tailorbird actually stitches two leaves together using plant fibre. A weaver bird knots long grass strips into a hanging pot with a tube for a door. When you have failed once at making a nest, you will never again call a bird's nest untidy.
Important rule: Never take a real nest, and never touch a nest that has eggs or chicks in it. Watch it from a distance. If the parent bird sees people near it too often, it may leave the eggs for good.
