My anecdotal accounts derived from videos are no better than the anecdotes I

I have a LOT more confidence in the quality of a concrete binary observation, e.g., "...the bird could not fly (UNTIL he emptied his crop, or the wind started blowing, or he reached a steep slope, etc)...", than in a guess about whether the wind was blowing (and how hard) on the occasions when he did fly.

i don't get what you mean about failed launch data being unreliable (assuming enough observations).

By evolutionary logic I find the behavior compelling evidence, anyways -- the CA Condor and that general body style have been regressing in size a long time.
