A Siberian Chiffchaff photographed at Dayet Dar Bouazza, just south-west of Casablanca, on 8 December 2019 by Benoît Maire.
If accepted, this would be the third record for Morocco of this rare Asian vagrant. Only two records have been accepted so far by the Moroccan Rare Birds Committee (MRBC): the first was captured at Oued Massa on 16 March 1998 (MRBC report No 6: Bergier et al. 2000), and the second was also observed at Massa on 13 December 2007 (MRBC report No 16: Bergier et al. 2011).
The Siberian Chiffchaff is still considered as a subspecies of Common Chiffchaff (Phylloscopus collybita tristis) by the IOC World Bird List, but it’s split as a full species (Phylloscopus tristis) by others (e.g. HBW alive).
Dayet Dar Bouazza is a small wetland that’s endangered by development. Despite this, it attracted a good number of rare birds during the last few years. Just last October, two Nearctic waders (American Golden Plover and Pectoral Sandpiper) were photographed at the site. Also, Richard’s Pipit is now a regular winter visitor at the site.
