Last night whilst admiring Graham Catley's super image set of the Frampton Oriental Pratincole I was struck by the apparent prominence of the pale tips to secondaries forming a weak but nice trailing edge. It can be seen most clearly on the images taken against a dark background.
Whilst I don't meant to question the id at all of such a well documented bird, I was wondering if pale tips to the secondaries is particularly normal for Oriental Pratincole, especially in spring?
Having had a couple of 'scares' with Collard Pratincole in Israel, I looked into this feature quite a bit in 2003 and remember being told that Oriental Pratincole shouldn't show any pale whitish/buffy tips to the secondaries at all.
Does anyone have any thoughts, or experience, on the variation of this feature? I will confess to having no experience with the subject species.
Best to all,
