Dead Sea sparrow underparts are grey-white. The female is like a small house sparrow, with a streaked brown back, greyish head and buff-white underparts. She is paler and smaller billed than the house sparrow, and sometimes shows yellow on the neck sides. The eastern race "P. m. yatii" is sandier, and the male has a yellow wash to the underparts.

As its name suggests, is a breeding bird around the River Jordan, Dead Sea, and into Iraq, Iran

An unusual feature of the Dead Sea is its discharge of asphalt. From deep seeps, the Dead Sea constantly spits up small pebbles and blocks of the black substance. Asphalt-coated figurines and bitumen-coated Neolithic skulls from archaeological sites have been found. Egyptian mummification processes used asphalt imported
