Consider the following statements about the Robin bird and select the true statement. A. It makes its nest among stones. B. Their nest is made up of all kinds of things, even pieces of wire and wood. C. They hatch the koel birds egg along with their own. D. They make a soft and cosy nest for their babies. Correct Answer A and D only

Concept: 

  • Birds build nests to lay their eggs and incubate their younger ones.
  • Different birds build nests at different places, some on ground level, some high up on the tree.
  • Different birds use different techniques and different materials to build their nests.

Explanation:

Robin:

  • They are diurnal birds.
  • It lays its eggs between the stones.
  • Their nest is made up of grass.
  • On top, they have soft twigs, roots, wool, hair and cotton wool.
  • Their nest is soft and cosy.
  • Baby robin birds have a red mouth on the inside.
  • Mother bird feeds small insects to the baby bird.

Thus, 

A. It makes its nest among stones: True

B. Their nest is made up of all kinds of things, even pieces of wire and wood: False

C. They hatch the koel birds egg along with their own: False

D. They make a soft and cosy nest for their babies: True

Additional Information 

Crows nest:

  •  A crow’s nest is made of all kinds of things, even pieces of wire and wood.
  • A cuckoo bird never makes its nest.
  • It lays its egg in the nest of a crow.
  • This ensures that there's a higher chance of clutch formation. (The clutch is the number of eggs laid).
  • The cuckoo's eggs resemble those of the crow in pattern and colour, which helps them in nesting.
  • The cuckoo is a brood parasite which means it lays eggs on other birds' nest.

Historically, the production of wood charcoal in locations where there is an abundance of wood dates back to a very ancient period, and generally consists of piling billets of wood on their ends so as to form a conical pile, openings being left at the bottom to admit air, with a central shaft to serve as a flue. The whole pile is covered with turf or moistened clay. The firing is begun at the bottom of the flue, and gradually spreads outwards and upwards. The success of the operation depends upon the rate of the combustion. Under average conditions, 100 parts of wood yield about 60 parts by volume, or 25 parts by weight, of charcoal; small-scale production on the spot often yields only about 50%, while large-scale became efficient to about 90% even by the seventeenth century. The modern process of carbonizing wood, either in small pieces or as sawdust in cast iron retorts, is extensively practiced where wood is scarce, and also for the recovery of valuable byproducts (wood spirit, pyroligneous acid, wood tar), which the process permits.
