On hot, summer days one may see birds, specially the Philippine Maya, wallowing around in bare, dusty, sandy patches in the yard.
Naturalists aren’t quite sure why birds take sand baths; some say it helps control pests and lice. It seems a sand or a dust bath helps clean debris out of birds’ feathers and soothes their skin.
A bird fluffs up its feathers and proceeds to loosen up the sand with its wings and feet. Some birds even lie down and roll in the sand. Dust settles on feathers and filters down to the bird’s skin, coating everything. Finally, the bird shakes most of the dust off and then spends times preening and grooming its feathers.
