The National Red List Project

Please note, this National Red List website contains a subset of data whilst we transition to national focal point driven data uploads. We thank you for your patience with this and welcome national contributors to get in touch to update their national dataset. Terms of Use including citation guidance are found here.

The previous dataset is available via: https://archive.nationalredlist.org/. This site is no longer updated but can help with most enquiries whilst we focus on redevelopment.

Species
Taxon distribution as listed in assessment
This species is thought to be a common visitor to the country from August to April (Pedersen et al. 2017), occurring as a passage migrant and over-wintering species in the UAE.

Habitat
Habitat details as listed in assessment
This species prefers still or gently flowing water with plenty of small fish, and with reeds, rushes or shrubs on the banks for perches. Streams, small rivers, canals and ditches are favoured to open waterbodies, but it also uses lakes, ponds and flooded gravel pits. In winter it becomes more coastal, also using estuaries, harbours and rocky seashores. Although not recorded for UAE, in Europe, the main prey is fish but will also consume aquatic insects, flies (Diptera), butterflies and moths (Lepidoptera), amphibians (Rana), crayfish (Astacus), prawns (Palaemon), shrimps (Gammarus) and isopods in winter. Very occasionally it feeds on berries (Rubus, Sambucus) and stems of reed (Phragmites) (see del Hoyo et al. 2001).

Assessment status criteria
C2a(i,ii); D
Assessment rationale/justification
This species has an extremely small over-wintering population size within the UAE. This population is inferred to be in decline due to development, with artificial water sources appearing to attract fewer individuals than natural ones. Therefore, the species is assessed here as Critically Endangered under criteria C2a(i,ii); D.

Conservation
Threats listed in assessment
Changes in land-use and the possibility of oil pollution could affect this species in UAE, but the severity of these threats towards this species is unknown.;Individuals that visit the UAE are also likely to impacted by threats operating outside of the country. Long term declines in its global range (outside of the UAE) are thought to be due to chemical and biological river pollution. The two main sources of this are most likely industrial waste disposal and agricultural chemical runoff. Canalization of streams and clearance of emergent vegetation to improve drainage result in loss of feeding habitat and nesting habitat (although the latter is not relevant to the population in UAE), and declines in fish numbers (Tucker and Heath 1994). It is also at risk locally from persecution to protect fish stocks (Woodall 2016).

Further information
History
It is assessed that in 1996, the national Red List category of this species would have been the same as in this assessment, however, it is not certain that the species would have been inferred to be in decline, so the criteria string in 1996 would have been assessed as being Critically Endangered under criterion D alone.
