Taxonomic Notes
Butorides striata;(del Hoyo and Collar 2014) was previously split as;B. striata;and;B. virescens;following AOU (2003), and before then;B. striata;was split as;B. striatus;and;B. sundevalli;following Sibley and Monroe (1990, 1993). Gender agreement of;B. striata;follows David and Gosselin (2002).
Taxon distribution as listed in assessment
This species is a common resident along both coasts of the UAE, but uncommon to rare further inland (Pedersen et al. 2017).

Habitat
Habitat details as listed in assessment
This species is mainly coastal. It favours mangrove habitats, but is also found along rocky and sandy coasts, coral reefs, harbours, breakwaters and jetties (Richardson 1990, Jennings 2010, Aspinall and Porter 2011). It is occasionally found at inland wetlands, including water-filled rubbish dumps, sewage treatment plants and gravel pits (Richardson 1990). The species forages mainly in stands of Black Mangroves Avicennia marina. In Arabia, it has only been observed to feed on fish, but elsewhere it also takes crabs, shrimps and other invertebrates (Jennings 2010). The breeding period lasts over spring and summer; the species may be double-brooded. Nests are loose structures of sticks and algae, which are hidden in bushes or rock crevices. The clutch size is not known; evidence from the Red Sea suggest that clutches contain four eggs (Jennings 2010).

Assessment rationale/justification
This species has a restricted resident population in the UAE, which might qualify it for listing as Vulnerable. However, the population is increasing, and the potential for immigration from outside the UAE remains very high, as the breeding population in the wider Arabian Peninsula is likewise increasing. Therefore, the species's status has been adjusted down to Near Threatened at the national level.

Further information
History
The species was much less common in 1996, qualifying as Endangered, adjusted by one step to VU. The population increases for this species are likely a result of increased availability of artificial water sources.
