For what it's worth I didn't get the questions either, and as far as I know my ISP has never withheld any real mail for any reason.  I just checked and they are not holding this message, so for some reason it never arrived.  This doesn't bother me, since my bird identification skills are minimal, just letting you know in the interests of investigation.

Roger, good to hear from you;  thanks again for your correction on the ?avionics?.  A few points here:
 
  1. I usually send email with Microsoft Outlook, usually ? and always if I include a picture file ? in HTML format (could that be a problem for some recipients?).  On both relevant occasions I followed the same process of ?insert?, ?picture?, ?from file?.
 
2
         My pictures are pre-edited to less than 100kb ?with predictable loss of quality, depending on the picture.  They are anti-virus scanned before transmission.
 
3
         I have noticed no inexplicable increase in a file size since that one occasion we discussed.

         If you are not getting messages this may be due to your filter settings.  Whenever I check the archive, my messages are always there. If you think you may be missing messages, you may wish to check the archive.   (Incidentally the signposts to the archive and other contacts seems to have dropped off recent messages progressively, although I noticed they reappeared on Terry Gourlay?s of a couple of days ago)
 
As to Philip?s concerns ?
 
In my original message (which I appreciate does not help you) I said I would allow a couple of days for mulling.  As to how birds are supposed to hold their wings, I can only say that the bird in question was a White-necked Heron.  It was one of 3 flying away from a farm dam.  By way of a test of the system, I enclose a fuller sequence.  Incidentally the small protuberance below the body (figs 2 & 3) that looks (misleadingly) like a bill is in fact the lower curve of the heron?s neck, which is extended and bobs up and down when the bird is in ?power? mode (see fig 1).
