What is the maximum lift possible, or ever measured.....in a thunderstorm I would presume.
ie 10,000fpm?
This would be as it applies to very small objects...such as birds.
A&M report is suggesting the bird deaths may have been the bends, we are contemplating their analysis.

This NCAR plane might have found a good one or two, pretty close to 10,000 fpm.

"Updraft cores may be relatively undiluted in large High Plains thunderstorms; a study of a supercell storm investigated during CCOPE provides one example in which a huge updraft core (maximum updraft speed about 50 m/s) was relatively free of entrainment effects (Musil et al., 1986). "

Pretty sure I'm calling BS on that one - birds don't usually fly into thunderstorms, much less large groups of birds at night. On top of that the pressure differential (even if rapidly applied) from sea level to maybe 20,000' would not be enough to produce the bends. Hypoxia would be much more likely, but would still require a large flock of birds to be flying into a thunderstorm together in the first place. Pretty thin logic.

The bold text describes the average aggie fairly well!
