The Nubian Nightjar has a pale rusty brown plumage, with white spots on its wings and on the tips of its tail, which are visible in flight. The sexes are similar. The male song sounds like a distant dog bark and can be heard in spring and summer. It feeds mostly on moths that it locates from the ground, using mainly its sight, and therefore is more active at dawn and dusk and on nights with strong moonlight.
The Nubian Nightjar is a rare resident and summer breeding species at the northern Arava and in the Dead Sea area. Its population is estimated at 60-70 pairs in the Sodom Basin, 10-20 pairs in the northern Arava, 5-10 pairs in the northern Dead Sea and a few pairs in the southern Arava (Haviv & Perlman 2016, Moran Bakish pers. comm., Noam Weiss pers. comm.), with a total of 75-100 pairs. Until the early 1980s, it was a relatively common breeder in extensive areas in the Arava and Dead Sea valleys, as well as in the Jordan Valley north up to Bet She’an. The drastic reduction in the number of individuals and in its range was recorded during the 1980s. At the end of the decade, the species population was assessed at 15-20 pairs in the Arava and a few pairs in the Jordan and Bet She’an valleys (Shirihai 1996).
Salt marshes with scattered tamarisk trees, rocky flats and sand dunes with sparse vegetation in desert Sudanian climate.
Habitat destruction – mainly expansion of cultivated areas at the expense of salt marshes.
Poisoning – the species was apparently affected by insecticides.
Roadkill – the species is very susceptible to roadkill because of its tendency to freeze on the spot when it is blinded by vehicle headlights and low-flying hunting behavior.
Direct disturbance – mainly by off-road vehicles.
No specific conservation measures have been taken for this species to date.
The core areas in which there is relatively dense Nubian Nightjar nesting should be preserved and receive statutory protection.

Current Occupancy Map
Distribution maps
The maps presented here provide visual information on the distribution of species in Israel in the past and present, and the changes in occupancy and nesting density during the comparison period. For further reading
Relative Abundance 2010-2020
Breeding density values as calculated from observation records and expert opinions.
Relative Abundance 1980-1990
Breeding density values are based mainly on the book Birds of Israel (Shirihai 1996).
Occupancy difference 1990-2020
A map that expresses differences in the breeding distribution between the evaluation periods (1980-1990 versus 2010-2020). Negative value - species previously present but is currently absent, positive value - species has not been recorded previously and is currently present, zero - no change in occupancy.
Relative abundance difference 1990-2020
A map that reflects the changes in the relative abundance of the species between the evaluation periods (1980-1990 versus 2010-2020). Negative values - decline in abundance, positive values - increase in abundance, zero - no change in abundance.
