#13 To build nests, swallows use feathers, branches, dirt.
#14 The main and favorite pastime of swallows is flying.
To rest, the bird perches on trees, wires, and poles. It is difficult to meet a bird on the ground since it will be quite difficult to take off from it like a feather.
#15 Short legs and too long tail do not allow the bird to move quickly on the ground and this makes it vulnerable to predators.
