Thanks, I accept that explanation so no need for references. What I was a
"little bit skeptical" about is that being attributed as the best
explanation for any particular bird seen without feet. I apologise for not
making it clear. At the very least I think there are a number of plausible
ways a bird could lose feet, and not the data to make entanglement the
immediate best explanation. As I said in my initial email; "not to say it
couldn't happpen." I just think it's hasty to immediately put that forward
as the probable reason for podlessness (I made that word up!) in response
to somebody asking about seeing a bird in such condition.
