The fact that the emargination on P3 falls ''just'' within the bunched secondaries/tertials was a concern to me..however the pp (62.5%) of overlying tertials is..I believe outside the norm for A.scirpaceous?
Ken,
The primary projection does not look very long on this picture, that's true. However it should be noted that the way the bird holds its wings ("bent inwards" if that makes any sense) is perhaps misleading and render the estimation of the PP somewhat uncertain. In any case, the PP looks shorter than on an average Eurasian reed.
Yet, considering all the other features visible on this truly excellent photograph, namely:
- fairly prominent eye-ring
- richer rufous tones to the face, wings, uppertail and tighs (and lack of olive tones altogether)
- tertial pattern more contrasting than on Blyth's
- alula's dark even on the outer web
- position of the emargination on p3, compare:
http://www.pbase.com/image/98642769 (note emargination on p3/p4 and even slightly present on p5)
- lack of emargination on p4 (that's just a small notch on the outer web of the feather on the subject bird, not an emargination)
...I think it's a relatively straightforward
A.scirpaceus.
