Assessment rationale/justification
This species has a small resident population within the UAE. The current population trend is unknown, although it is thought have undergone a population increase (at least up to the 1990's), and this increase could be continuing. Based on its small population size, this species is listed here as Endangered under criterion D.

Taxon distribution as listed in assessment
This species is an uncommon to rare resident in the UAE (Pedersen et al. 2017). It occurs mainly in the area of Abu Dhabi City and Al Ain (Abu Dhabi Emirate) and in the northern emirates (Jennings 2010). Individuals have also been observed on Das Island (Richardson and Aspinall 1998, Jennings 2010). One dead individual was recovered in a separate area of coastal Abu Dhabi Emirate, but it is unsure whether this represents just a vagrant or dispersing individual, so this locality is not included in the map.

Habitat
Habitat details as listed in assessment
This species is found in a great variety of habitats. It favours proximity to human settlements, like the vicinity and outskirts of villages near cropland and refuse dumps, but also centres of large towns with sufficient open space for hunting (Jennings 2010). Its natural habitats include open country with scattered trees, forest edges, semi-desert and desert far away from human sites (Jennings 2010, Aspinall and Porter 2011). It hunts during the night. Its diet includes rodents (e.g., mice, rats or shrews) and birds (e.g., White-cheeked Bulbul Pycnonotus leucogenys, Common Myna Acridotheres tristis, House Sparrow Passer domesticus and domestic Rock Dove Columba livia), but it seems to avoid taking reptiles (Cunningham and Aspinall 2001, Jennings 2010). It breeds between December and June (Jennings 2010). It nests in tree holes, caves, crevices in rocks and abandoned buildings, or nest boxes (Jennings 2010). No nesting material is used, instead the eggs are placed directly in a small cup formed of the droppings, remains of prey and debris that accumulated in the nesting cavity (Jennings 2010). The clutch size is usually three to six eggs, but may be increased with increasing food availability (Jennings 2010).
Threats and conservation measures listed
Threats listed in assessment
Within UAE, Aspinall (1996) highlighted the main potential threats to this species as the loss of nesting sites (either due to tree felling or the demolition of ruins), collisions with vehicles, and persecution as the bird may be considered an ill-omen.
History
It is assessed that in 1996, the national Red List status of this species would have been the same as in this assessment.
