Just watched a crow come into our garden where we had put some stale bread rolls. The 'early bird' (sorry) crow landed on our table and picked the biggest piece of bread. Compared to the AUW of the crow - it must have been a significant weight (notwithstanding that it had just rained so "contamination" was involved). Anyway, when the crow eventually organised the load, it got airborne and (just) made it over our fence , flew downwards along our sloping field, and eventually gained some altitude and flew away. As a human ex 744 operator, I was impressed that birds can do all those calcs without a computer anywhere.
I know - it could have dropped the bread but you know what - it didn't.
Well done Mr Crow without Perf "A".
