Justification of Red List category
This species has an extremely large range and the population size is extremely large, hence does not approach threatened thresholds for the range or population size criteria. The population trend is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds under the population trend criterion. For these reasons the species is evaluated as Least Concern.
Population justification
In Europe, the total population size is estimated at 4,620,000-13,200,000 mature individuals, with 2,310,000-6,580,000 breeding pairs (BirdLife International 2021), and comprises approximately 15% of the species' global range, so a very preliminary estimate of the global population size is between 30,800,000-88,000,000 mature individuals, although further validation of this estimate is desirable. In Europe the trend for this species is not known (BirdLife International 2021). As no other data are available to derive trends, the global population trend for this species is unknown
Trend justification
.
This species is found in arid, open, sparsely vegetated country, including dry plains, mountain and lowland steppes, semi-desert, wadis and desert margins, commonly where burrowing rodents, such as gerbil (Rhombomys opimus), occur. In Armenia, it is found in rolling semi-desert with Tamarix, Artemisia, Euphorbia, Alhagi, Atraphaxis and Gypsophila, and is usually on south-facing mountain steppe with Astragalus. Breeding occurs from mid-April to mid-July in Israel, April-May in Jordan, March-June in Armenia and Baluchistan and sometimes as early as mid-February in Turkmenistan but normally late March to July in southern Russia and late April to mid-July in Mongolia. The nest is a shallow, bulky cup of dried grass, roots and hair, lined with hair, wool and feathers. It is set deep in a rodent burrow or burrow of a similar mammal and less often in and old bee-eater (Meropidae) hole or occasionally in a natural hole or crevice. Clutches are four to seven eggs. The diet is mainly invertebrates, particularly insects such as beetles and ants and vegetable matter. The species is migratory (Collar 2015).
The species is linked to some extent to populations of burrow-nesting rodents, which supply nest-holes. As a result, declines in these species, such as falls in gerbil numbers due to ploughing, may impact this species (Collar 2015).
