Answer 2

Q1.

a) Such upward movements are called thermals. Gliding birds, by circling within the rising air use the lift that the air movement produces and glide upwards, or soar.

b) Down feathers are found close to the body and are very soft and fluffy because they do not have a rachis or barbules. This means their barbs are free to move around, giving them that fluffy appearance but also trapping air and providing insulation for the bird.
