Mack closed the second set of doors and began to pound on them.
When a passerby asked him what he was doing, he replied, "I've got 2000 pigeons in the back and I think they're too heavy for this old bridge. I'm making the 'little buggers' fly around so they'll lighten the load 'till I get across".
Will Mack's idea lighten the load or will it be the same?

It will be the same.
The air pressure caused by the downward flapping of the wings will counter the benefit gained by the birds being in the air.
