Popis

Canada geese use four divisions of the Mark Twin NWR: Louisa, Delair, Cannon, and Calhoun. There was a shortage of cultivated crops, corn and soybeans, on all refuge units except the Delair which had crops approaching normal. Lack of food had little effect on Canada goose populations as three of the four units had significantly greater use than in 1968 when food supplies were abundant to the point of being surplus. The specific behavior of Canada geese on each division is outlined in this report.
