The down feathers of birds is a layer of fine feathers which are found under the tougher exterior feathers. Very young birds are clad only in down. Powder down is a specialized type of down found only in a few groups of birds. Down is a fine thermal insulator and padding, used in goods such as jackets, bedding (duvets), pillows and sleeping bags. The loose structure of down feathers traps air, which helps to insulate the bird against heat loss.Thus, if down feathers are absent pigeon will not be able to keep the body warm.Therefore, the correct answer is option D.
