Eastern or Western?
Juan Sagardia sent these photos from a couple of weeks ago. They were taken on Fuerteventura on the Canary Islands. This bird was a little over shadowed by a certain Abyssinian Roller and also an apparent Eastern Bonelli’s Warbler.
I have seen not seen Western Olivaceous Warbler (Iduna opaca). The question is whether this individual is a Western Olly, or a ‘Western…. Eastern’. That is to say, the reiseri form of Eastern Olivaceous Warbler (Iduna pallida reiseri), which occurs in NW Africa (close to /overlapping? with Western Olivaceous).
No information on dipping tail movement (present in Eastern Olivaceous, absent in Western Olivaceous). Opinion from those who know the subject welcome. Not easy!
and in case you missed it!
A couple more of Juan’s shot of the stunning Abyssinian Roller and that increasing familiar celebratory X men stand! :). All photos Juan Sagardia. See his Facebook Page.
