Identification d’une Hypolaïs rama capturée en Israël

Sykes’ Warbler, Iduna rama, is an Old World warbler in the tree warbler genus Iduna. It was formerly considered conspecific with Booted Warbler, but is now usually considered a separate species. Its breeding range is from the Caspian Sea area to Central Asia. It migrates winter in the Indian subcontinent as far south as Sri Lanka.
On the morning of the 21/9/08, Noam Weiss from IBRCE (Eilat) noticed a little brown bird in one of their mist nets. Arriving at the bird it looks confusing with a Phylloscopus jizz but the color of an Acrocephalus. Out of the net it became clear that this is a Iduna Warbler, but nothing like an Olivaceous Warbler. It looked very much like the Booted Warbler (Iduna caligata), but the head and bill were longer, the tail looked somewhat longer too and the shape was not as strikingly Phylloscopus like. After years of examining short winged Olivaceous Warblers that they occasionally catch at the IBRCE Ringing Station it was clear that this bird was actually a Syke’s Warbler.
