Indeed a used Zeiss FL 7x42 does look like an excellent fit. Saw one recently on the LCEGroup site but, as you suggest, it wasn't there for long

. Someone gave a link further up to the Scopeviews review of the Trinovid 7x35. Here's the 7x42 Victory FL one :

The criticism there of the field curvature may not apply to woodland birding; in fact quite the reverse since it may give the impression of increased depth of field. Wonder if tinted light under a woodland canopy would reduce chromatic aberration issues for you. Then again I suppose looking up into canopy there's still the risk of fringed silhouettes...
The Kowa BDII 6.5x32 might be worth a look for its fabulous FOV; reports of decent control of false colour issues though maybe distortion at the periphery might bring attention to itself while panning.
If I knew how to send a pm I'd be asking BFer edwincjones how he's getting on with the Kowa for woodland birding. I've seen a post over on Cloudynights where he suggested he preferred the Zeiss FL 8x32 perhaps suggesting he's finding the 6.5 magnification a bit low.
