Seven Savi’s Warblers - Jubail

Recently there have been a number of reeling Savi’s Warblers around Jubail with three heard in late February and seven heard by Phil Roberts on 25 March 2016. Whilst ringing at Sabkhat Al Fasl ten Savi’s Warbler we have trapped and ringed in the last two years. Birds have occurred mainly in the spring with seven records from 20 March until 18 April and three in the autumn from 26 September until 24 October. Savi’s Warbler previously had a status until this ringing project as a scarce passage migrant but our ringing records show the species is in fact an uncommon passage migrant through the Eastern Province of the Kingdom at least. These seven birds reeling also indicate numbers are increasing in the region. The subspecies fuscus we get in the Eastern Province of Saudi Arabia is darker coloured, has more obvious under-tail covert tips and some streaking/spotting on the throat making it look more like a River Warbler than the nominate subspecies. The throat markings are not as dark and well defined and the undertail coverts more warm toned than in River Warbler though and the supercilium is more obvious behind the eye.
