Its really just common sense and logic.
All migratory animals be they feathered, furred or finned migrate to and for a food response stimuli which centers around the need for nutrition and thus fecundity and overall survival of the species.
Mother nature and natural selection have installed premises which lead that the ones who find the best food source first and repetitively are selected for and as such will prosper while the others are selected against.
Food most certainly imprints and is a huge if not full part of the migratory instinct driver, such has been known since the beginning of animal behavioral sciences.

When I moved here in '83, the Klondike Volunteer Fire Department was touted as the statistical center of the greatest concentration of wintering white-fronts on the continent. Went to work for Doug's because you couldn't drive through Klondike on 14 without seeing thousands of them. That's over.
