Hi everyone,
in my last visit to Morocco we saw two very distinctive forms of Southern Grey Shrike Lanius meridionalis. The first, mainly found north of the Antiatlas mountains, it's more greyish and has a distinctive white superciliar line. We initially identified it as L. m. algeriensis.
The second looks somewhat smaller and is much paler overall, with more white in the wing, and (as in the specimen of my photos) no white supercilium. It was found south of the Antiatlas, which seems to establish the border between the two forms. Initially we identify it as L. m. elegans, but the lack of white supercilium contradicts all the illustrations I've consulted. On the other hand, algeriensis is supposed to have very poorly defined supercilium, or none at all...
Any oppinions? You can see photos (clickable thumbnails) of both forms in http://www.iyufera.com/tr0-morocco/tr-morocco01.htm
Regards from Madrid,
Ignacio
