The vultures were probably feasting on undigested bits that that cows ate and passed. Other birds do that as well.

Yes, we made it to the "Academy Awards." Mom embarrassed herself (and me) first by the dress she wore (left over from her 1919 prom but "repurposed" with various slits added and "modesty panels" removed), drinking what was on other people's tables when the waiters refused to serve her more drinks, and kicking and screaming when security was forced to remove her. There were damages from the last and I do hope that the kicks and blows she gave to the security people don't cause lasting damage but I am afraid that she's in for a bit of a jail spell. Calling "GLUON! GLUON! HELP!" didn't help her, but the screams of "What's humping my leg?" only added to the confusion.
