I immediately admit to no zoological knowledge on the subject whatsoever.

If you saw them, it wasn't soup...
My, probably useless, thought would be that birds fly at the most at something like 30 to 50 kts. So, they would stay out of the 100% solid peasoup, and just fly through the gaps in the rest, a luxury we humans do not have at 300 to 500 kts TAS....
As to the I in IFR (like Instrument... gettit?) I would think that while gliding, with a decent amount of lateral stability, they can probably feel they're level, they can certainly feel their speed, and in most cases they can probably see/perceive what's up and down. The anecdote about the WWII pigeons may well be accurate.

Brian,
Sorry, haven't explored your links yet, but will do.
