Ah. Thanks a lot, that was me:

If this is that way then he has completely misunderstood me. (I showed off
with my own work on the subject... maybe he hasn't even read the whole mail
before he forwarded it.) I was asking him for the reasons, if he has any,
why he flamed around so much on people's "ignorance". If he thinks that all
"bird-dinosaur" people are exactly the same then he is wrong, but likewise
he were wrong should he think BAND is a monolithic block. Of course he isn't
even alone in agreeing with Feduccia et al. (just nearly). Doesn't matter.

I see. But how are lift and thrust beneficial in grabbing prey?
