The Crowned Sandgrouse is a relatively small and short-tailed sandgrouse with a sandy brown plumage. The male has an orange throat and cheeks and a thick white-bordered black stripe around its bill on its chin and forehead. The female is densely striped and spotted and its throat and the sides of its head are yellowish. Light underparts and the contrast between its pale wing coverts and black flight feathers are visible in flight. Its call is uneven and reminiscent of a chicken-like chatter.
Resident in the Negev and Arava (south of the Dimona-Yeroham-Tse’elim line). It is nomadic over large areas and numbers vary from year to year depending on the amount of precipitation and food availability. Flocks are smaller compared to other sandgrouse and it inhabits more arid areas. Since the 1980s its numbers are declining, particularly in the northern part of its range.
Stony Hamadas, loess plains and the openings of broad wadis. Crowned Sandgrouse inhabit only arid deserts and are not found in cultivated fields. They fly to watering spots to drink, and therefore require a permanently available water source within several dozen kilometers from their nesting areas.
No specific conservation measures have been taken for this species to date.

Occupancy 1990-2020
The map shows differences in the species breeding distribution between the 1980's breeding map and the current weighted breeding evaluation. Negative value - species previously bred in the grid and is not presently breeding; positive value - species has not previously bred in the grid and is currently breeding.

Change in Relative Abundance 1990-2020
The map shows the changes in the relative abundance of a species in each of the distribution grids between the breeding map of the 1980s and the weighted current breeding evaluation. Negative values - decline in abundance; positive values - increase in abundance; zero - no change in abundance.
