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. The chirping song resembles those of house and Spanish sparrows, but is softer. The flight call is a high-pitched "chi-wit". This species is often silent. As its name suggests, is a breeding bird around the River Jordan, Dead Sea, and into Iraq, Iran
Poxte River River, which is a tributary of the Machaquila River. The Machaquila River feeds into the Pasión River, which flows into the Usumacinta River and into the Gulf of Mexico. The upper reaches of the Poxte River shares its drainage with the Mopan River, which flows eastwards into the Caribbean Sea. The Poxte River Basin itself measures long and is wide. The river valley drainage is broken and confused, and the land has been largely cleared of forest in order to graze cattle. The Poxte valley includes modern settlements of Las Nuevas Delicias, La Lucha, Santo Domingo and Boca del Monte.
