Because they're sea going birds, with wide beaks, that prefer to eat fish. Grains are grown in dry climates, such as grain farms. Although they might eat grains, if you ad it to some raw fish.

That's a new version of an age old question. Pretty much the same reason pigeons can't eat rice or alkasalzer. Birds will fill themselves to capacity and take off flying, rice and such materials expand in the birds stomach's and halt their flying by either blowing up their stomachs or just causing unbearable pain, either way, sending them to plummet to their deaths.

didnt know they couldnt! but i would guess either it gets caught in their pouch, or their stomachs cant process it somehow, missing whatever enzyme it takes to break it down. swells up in their digestive track? whatever the reason, pelicans are cool and awesome to watch gliding along the water line.

they eat til they are full and then the grain swells up and expands the stomach, sometimes causing it to explode.
bad idea.....why they throw bird seed now at weddings, too.
